The principles of the battery

The VGP-BPS8 VGP-BPS8A battery is a kind of energy conversion and storage devices. She is a physical or chemical reaction can be converted into electrical energy. Battery is a source of chemical energy, which consists of two different elements of the electrochemical activity of the composition of positive and negative electrodes, respectively, the two electrodes immersed in the media to provide conduction of the electrolyte, when it is connected to an external carrier, through its conversion to provide internal chemical energy can be. As an electrical storage device, when the two metals (usually a difference in the metal) are immersed in the electrolyte, they can be conductive, and the “plates” have a certain electromotive force between two. Size of the emf (or voltage) with the use of metal on different types of batteries for its electromotive force is also different.

Batteries chemical practices can be divided into two types: batteries. Made after the original battery can generate current, but the discharge is completed Jibei abandoned. Battery also known as secondary batteries before use should proceed to charge fees for use after discharge, the discharge can also be loaded after the re-use. Battery charging, the energy converted into chemical energy, the discharge of converting chemical energy into electricity. Dell Inspiron B120 battery  Dell Inspiron B130 battery

In cell chemical chemical energy directly into electricity by the battery is carried out within the spontaneous oxidation, reduction and other chemical reactions the result of the reaction was conducted in two electrodes. Negative active material of the more negative potential and an agent of the stable reduction in the composition of electrolytes, such as zinc, cadmium, lead active metals and hydrogen or hydrocarbons. Positive active material for a more positive potential on the composition of the electrolyte of a stable oxidizing agent as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or the air, halogens and their salts, oxygen-containing acid and its salts, etc.. Electrolyte is a good ionic conductivity material such as acids, alkalis, saline, organic or inorganic non-aqueous solutions, molten salts or solid electrolytes. When the external circuit disconnected, although there is potential difference between the two poles (open circuit voltage), but there is no current, stored in batteries are not converted to chemical energy into electrical energy. When the external circuit is closed, the two electrodes under the effect of potential difference there is current flowing through the external circuit. The same time, the battery inside the electrolyte are not due to free electrons, charge transfer must be accompanied by two poles of active material and electrolyte interface, the reactions of oxidation or reduction, and reagents and reaction products of mass transfer. Charge transfer in the electrolyte, but also by the migration of ions to complete. Thus, in the normal transfer of battery charge and the process of mass transfer is to ensure that the conditions necessary for normal production of electricity. When charging, the PB994A PP2182D battery inside the transmitter power and direction of mass transfer and discharge exactly the opposite reaction of the electrode must be reversible to ensure the opposite direction to the mass transfer and mass of normal electrical processes.

Therefore, the electrode reaction is reversible, a necessary condition for the batteries. Reaction of the Gibbs free energy (coke) F is the Faraday constant = 96,500 basis = 26.8 ampere-hour n the equivalent number of the cellular response. It is the reaction of the battery and the emf of the battery between the basic thermodynamic relations, but also calculate the energy conversion efficiency of cells of the basic thermodynamic equation. Indeed, when current flows through the electrodes, the electrode potential must deviate from the equilibrium thermodynamic potential of the electrode, a phenomenon known as polarization. Current density (electrode surface unit adopted by the current), more polarization worse. Polarization is caused by the energy loss of the battery of important reasons. Polarization for three reasons: ① from the cells caused by different parts of the polarization resistance is called Ohm polarization; ② electrode - interface layer caused by electrolyte charge transfer blocked the process of polarization is Name polarization activation; ③ electrode - electrolyte interface layer caused by the slow mass transfer of polarization is called concentration polarization. Reduce the method of polarization is to increase the reaction zone to the electrode, which reduces the current density, increasing reaction temperature and improve the catalytic activity of the electrode surface.

Seven points to keep in mind about car batteries maintenance

Car battery is important, its function is to provide an electric starter, the engine starting or operating at low speed for the ignition system of motor and other electrical equipment. High-speed operation when the engine when the generator enough, the VGP-BPS8 battery can store excess energy. Unfortunately, it is generally ignored by most people. I do not know the proper maintenance of batteries to keep it plenty of power, is an important part of vehicle maintenance. The following will introduce the conservation of car battery connected to knowledge and common sense, to help you better understands the use and maintenance of the battery to extend battery life.

Car battery car battery works the vast majority of lead acid batteries. In simple terms, it is a chemical energy into electrical energy capable of electrochemical devices. Lead acid battery in the positive and negative plates, bulkheads, shell, etc. electrolyte and wiring trailer hitch and the discharge of chemical reactions depend on the active positive plate (lead dioxide PbO2) and the negative active material (sponge of pure lead, Pb) in the electrolyte (sulfuric acid composition of H2SO4 and H2O water) and as a result. A standard 12V lead-acid VGP-BPS8B battery contains six modules, each of the power of electricity is about 2V (one for each power supply has a positive and negative column: column is entered the positive sign “+”, dark brown negative column when a “-” sign in pale gray).

Traditional batteries will occur in the electrolyte is in decline is because the frame plate door with traditional batteries lead alloy of antimony, antimony will pollute the negative plate of pure lead sponge, weakened after the battery is fully charged in a Counter electromotive force resulting from the decomposition of excess water, a large number of oxygen and hydrogen, respectively, escaped from the positive plate and negative, so the reduction electrolyte.

Without maintenance (maintenance free) batteries into the design principles and traditions of the battery on a coherent strategy, the use of thicker plate materials, important difference is that the plate is consistent with lead calcium alloy. In the electrolysis reaction, it can reduce the flow of excessive burden, reduce the rate of vaporization of liquid, thus reducing the loss of electrolyte, compared to prolong battery life.

Discharge and load

In the year (discharge) process dioxide very edge of lead (positive), the spongy lead (negative), and sulfuric acid electrolyte chemical reaction occurs to produce the discharge of lead sulfate (PbSO 4) and d water (H2O), positive and negative plate the difference between reduced. Because the battery voltage depends on different electrode materials and electrolyte concentration, so the reaction after discharge, the battery loses power. Charging process (charge) and discharge process to the contrary. Current in the generator under the action of sulphate of lead and water lead dioxide (positive), the spongy lead (negative) and sulfuric acid, plates, electrolyte concentration restored, the acer-batcl50l-battery-p-17203.html”>BATCL50L battery of energy.

Caution

1 to start the car every time startup should not exceed 3-5 seconds after starting interval of at least 10 seconds.

2 vehicles often short driving distance open-window open will result in a prolonged state of battery charge less to shorten the lifespan. On the highway driving at a constant rate of 20? 30 minutes, may give enough time to recharge the battery.

3, driving a day before leaving the car, check and ensure that all lights and other electrical appliances (such as radios, CD) has been closed. Because it may drain your battery.

4, if the battery runs out, to ask the fire (Jump-Start, also known as tie-lines) to begin immediately possible a constant speed (such as highway speed) drive at least 20? 30 minutes to fully charge the VGP-BPS11 battery.

5, in the full discharge of the battery case, ask the fire may be unable to help you start your car. In this case, you must use a dedicated battery charger for slow charging.

6, where cars are not long-term investment should first fully charge the car. At the same time every month, launched his car, operation at medium speed for about 20 minutes. Otherwise, place too long, it would be difficult to start.

7 to understand the life of the battery. Using more than 4 years, the recommended replacement.

Waste batteries repair is necessary

In recent years, people blindly focused on economic development at the expense of environmental protection to the environment have had an undeniable impact. While environmental issues and livelihoods in this regard would be of concern to all the specific details of our lives, on drums, for example, domestic civil society over 20 billion batteries a year, consumption of 6 billion, coupled with other types of cells, their number is very striking. Then we often use VGP-BPS8B battery electric vehicles, many people are not very expensive.

The advent of electric cars and pop will also be the standard with a large number of battery electric vehicles will be used. As the batteries of electric vehicles as a result inevitably bad, then the batteries of electric vehicles is necessary to lay broken VGP-BPS8 Mody? Is this not the case? Reuse of waste batteries will be repaired or if it is the resource for the environment would be very beneficial. Of course, this would undoubtedly promote the formation of piles of the waste industry to repair, and become industry leaders in the industry chain.

Batteries food waste is a high technology, why should we spend the effort to study the batteries Fix It? To return used batteries in the restoration work that we do not want to be as simple as that. Waste batteries need to have a professional repair equipment repair, and repair personnel professional, such a procedure is not telling the truth, like a VGP-BPS10 battery to change it. But from the standpoint of environment and resources is not the case. So how can we understand the specific terms used batteries repair industry? While speaking briefly about restoring the bar normal cell into repair mode.

The repair process of the battery in the operation of wastewater from the battery is over, so that positive and negative aspects of the machine are correct, the machine entered the charge state of repair, repair cycle 10AH is 5-8 hours, and 20Ah need 8-12 hours to get to the battery terminal voltage to 16V or more to stop the repair. Just for the initial discharge time allowed, are renewing a test discharge of the battery can. Then you will find restored before the discharge time much longer than the repair, indicating that the VGP-BPS11 battery has a positive effect repairs, as the ability to reach more than 70% of the plant can be operated.

Talking about battery temperature

Temperature characteristics: When the rechargeable battery in the electrolyte and the electrode body rate of migration of film and temperature are closely related, if the temperature fluctuations significantly influence the technical performance of rechargeable batteries.

Storage temperature: Under normal circumstances, the VGP-BPS9A battery due to internal fluid, and low temperature will destroy the long-term storage of chemicals inside the battery, it is proposed conditional case, the temperature Storage is not lower than -20 ℃, while the high temperature also the battery can not achieve its rated capacity, the storage temperature generally not exceeding 40 ℃. Normal storage temperature of the rechargeable battery of -20 ℃ ~ 65 ℃ when the temperature dropped below -20 ℃, the battery will be consolidated into the electrolyte, the internal resistance of the battery becomes infinite, the battery will not be available. When the temperature exceeds 65 ℃, the electrolyte side reactions occur which produce large quantities of gas, electrode deterioration of the film adhesive resin can occur, causing the entire cell aging and declining, even short-term break.

Charging temperature: In general, accusing a temperature of 0 ℃ ~ 45 ℃. Discharge temperature: In general, the discharge temperature of -20 ℃ ~ 65 ℃, but in some cases, can use batteries at low temperature and high temperature VGP-BPS8A battery. Battery before leaving the treatment plant after a general discharge, to prevent the transit due to vibration or other causes of short circuit, usually a new battery is not charged or containing only about 20% of electricity. A new battery or long-term unused because the battery may not fully activate the active substance before use usually takes two or three cycles through the small streams (0.1C) charge and waste treatment, in order to reach the rated capacity. A long time not to use the state of the battery must be stored and can be pre-filled 50% to 100% of electricity after storage, has proposed to charge the battery once every three months to restore the capacity of saturation.

Battery Caution: 1.Do not incinerates or disassembles the VGP-BPS8 battery, in which chemicals are corrosive, will damage the skin and eyes. 2. Do not pull on the drum tracks or connectors; solder joints, and joints to prevent injuries. 3. Different types of batteries can not be mixed. 4. Different types of welding of the battery, welding, etc., you must use the connection piece. 5. First before use with a small current is fully charged. 6. Parallel does not charge, or they will produce irregular charging currents. 7. can not be used in reverse, short-circuit the battery or do. 8. Fully discharge the battery; it should be to extend the charging time to reach power saturation. Please 9. batteries stored in a cool, dry, ventilated, temperature does not exceed 45 ℃ environment. 10. in the battery is fully charged or half-full situation; do not store a large number of batteries at high intensity. 11. Do not contact the acid gas to prevent the fire near the source.

What is microbial cell?

Coal, oil, natural gas, is currently the main source of energy in human life. With the development of human society and the improvement of living standards rise, the energy consumption. However, this natural gift of VGP-BPS13/S energy through the major changes in the earth’s crust millions of years, gradually accumulated quantity are numerous, but limited after all. Therefore, it is finally overcome with an energy crisis in one day.

Of course, you can recharge your batteries on many aspects. As solar energy is a major source of energy. In addition, such as geothermal, hydroelectric, nuclear fission can emit a lot of heat. Experimental studies have shown that demonstrate the use of micro-power generation, the people a better future.

There are many types of batteries, fuel cells are a rising star in this family. The Laptop battery is generally positive, the negative electrode, electrolyte composed of three parts, is fuel cells, is also true: Let the fuel in a negative chemical reaction, loss of electron oxidant to enable running in a cathode reaction, from the cathode through the wire received via the electronic. As with conventional batteries, this time, where it through the wire current.

Fuel cells with hydrogen, hydrazine, methanol, formaldehyde, methane, ethane, etc., as fuel and oxygen, air and hydrogen peroxide as an oxidant, and so on. Now we can the life of the microbial activity of the so-called “electrode active material, such as fuel cells, and then much like the fuel cell to convert chemical energy into electrical energy of microbial cells.

As a micro-VGP-BPS8 battery-electrode active material, mainly hydrogen, formic acid, ammonia and so on. For example, it was found that many bacteria is hydrogen, the heterotrophic bacteria are targeted more than 30 species, they are absorbed in a position to ferment sugars, alcohols, organic acids and other organic material, a chemical energy, perform the activities of their own lives, it is necessary, while the other part of the energy in the form of hydrogen released. With this hydrogen as a fuel it can produce hydrogen-based micro-batteries.

In a closed space vehicles, the astronauts how to get urine discharge? NASA developed a clever solution: use of micro-organisms Bacillus urine much ammonia to produce ammonia as an electrode active material was micro-battery, then treat it with urine, also won the power. As a rule, in the space under the conditions of 22 grams per person per day of urine, can be 47 watts power. Were for the same reason, also allows micro-organisms from the VGP-BPS9 wastewater nutrients and energy needed to get to produce the fuel cells.

Although the microbial cell is still in the pilot study stage, but it shows that the near future of humanity is more energy available.
