Give full play to your cell phone battery

At a time when we buy a mobile phone is always concerned about the use of mobile phones and maintenance, while neglecting the maintenance of its parts, in effect, is also a need for maintenance parts, especially accessories origin. A battery life of origin for more than two years, if the misuse May cause shortened life expectancy to six months or less, but buy original battery will need more than 100 rooms, very profitable! Here are some basic cell phone batteries, their proper use.

   

Battery charger for mobile phone the best time to use the original or may affect the performance of batteries, lithium batteries can not EP (Expert Pormance) charger to use.

 

Battery Lithium load is normally shorter in the 1.5 to 4.5 hours between when the charger is better not to invest more than 224 hours. A new Laptop battery in the first 4 to 5 charge time by charging time should be preferably 14 to 15 hours but not more than 24 hours, each fully discharge and then recharge as much as possible, after such a cell after each use to get the best memories.

 

Charging and discharging of the ambient temperature should be close to room temperature (20 degrees), temperature will affect the battery charge and discharge capacity and talk time. Such as: battery exposed to extreme heat (40 degrees) when the battery capacity will be reduced by 40%, speaking time will be reduced by about 10%, the cell exposed to extremely cold places, the Dell Latitude D800 battery capacity will be reduced by 5%, call time is reduced to about 90%. Once the battery to restore and recharge at room temperature, but also back to normal.

 

Battery life depends on the number of repeated translation of power, he should try to avoid the battery still have some residual capacity along the way when the load is equivalent to shortening the life of the battery. Discharge may be mobile always-on, if the flow speed, may be the screen or the phone keypad, lighting open until the battery runs up to the automatic shutdown, it is preferable not to scavenger .

 

Improving the efficiency of the battery, first, require frequent cleaning of the contact points of the battery can be used Eraser point of contact should not be metallic conductors on the battery if the VGP-BPS10 battery short - circuit may cause harm. Plus the one hand, in a sacrifice of their lives alone should use a quieter approach, short of ringtones. To use the savings mode is the most mobile phones available in “non-DTX-power streaming saving mode so that the Director of talk time can be 30-50%.

How to choose an agent driver

How to choose an agent driver? This makes the battery design to address an important issue but to solve this problem, we must be clear user performance of lithium iron phosphate specific requirements applicable to electric vehicles on the iron phosphate lithium performance requirements of the Laptop battery and economic needs, for example, we must accurately understand the user for more than eight specific requirements, and use the data to be described. According to specific requirements of the user, we can design to meet the needs of user’s lithium iron phosphate, into the design process, how to use the official driver to improve battery performance is that each designer must address one of the problems.

 

1 by positive and negative active particle size and morphology of select agent driver. To effectively conducting electrodes to form networks, must be the same as above diagram network driver, it must be driver node, the node by the electrical conductivity of the graphite conductive to act as the particle size particle size in better and near active substances. Fulcrum must be conductive, they must be like octopus tentacles and the particles of active material, such as smoke two, they have a very fine size, there must be a string like morphology, which pivot from the SP -Li to act as the most appropriate. Pivot and the nodes must be a link between the sons, they have good conductivity, have a linear morphology, VGCF and carbon nanotubes specifically to meet these requirements. Therefore, to form positive and negative electrodes of conductive network effectively, you must attach the different morphologies with features different sizes of particles of the agent driver.

 

2, according to the performance requirements of VGP-BPS10 battery power to select the conducting agent. Depending on the use of lithium iron phosphate, the user must provide magnification different requirements, such as requiring the battery to discharge 10C continuous, 20C pulse discharge. At this time we are negative active material according to the conductivity of the powder (do not attach importance to these data before we can really be measured by four probe method, A123 in its patents and articles published in the first mention of this setting), the user of the battery capacity required to choose than the official driver. If you are negative active material conductivity is low, to achieve high magnification, you must choose a high conductivity of the agent driver. At the same time using several cases of conductive agents, we must improve the rate of high conductivity of the agent driver.

 

3, as the performance of battery power and high and low temperature performance requirements choose Agent driver. In the commonly used conductive agent, carbon nanotubes not only a good conductivity, but also has good thermal conductivity, but also the electric double layer effect. (Which is the role of lithium-ion batteries in other literature, have a very detailed description) in particular, thermal conductivity, and phosphate type of high power lithium iron when it is work d ’significant expansion of current payments, the VGP-BPS9/B battery internal resistance and polarization for the reasons for releasing lots of heat, heat the need for rapid dissemination of these, otherwise it will lead to incidents of battery safety. Therefore, often in great working condition magnification and high temperature, the professional status of lithium iron phosphate to improve the ratio of one officer conductive carbon nanotubes is necessary.

 

4, as the total cost of the battery must choose the agent driver. Commonly used agent in the drivers mentioned above, SP cheapest, followed by the electrical conductivity of graphite, and then followed by the super-350G conductive carbon black, is the most expensive carbon nanotubes and VGCF, up to 4000-5000 yuan per kg. Thus, the premise of meeting the needs of users, to minimize production costs of the battery, use low price as much as possible conductive agent.

 

5, depending on the ionic conductivity were asked to choose an official driver. To improve the ionic conductivity electrode, the electrode must have a good ability to absorb liquids and appropriate porosity. This requires us to use large area, porosity, high conductive agent. Agent driver common table above we can see the technical specification, SP-Li and the carbon nanotubes have all these characteristics.

 

6, to reasonably determine the amount of conductive agent to join. Agent driver in improving the performance of the battery power is concerned, although an important but not join the more the better performance of the battery power. Mi Gao Rui Shite company was adding up the amount of conductive agent specialized experience, experiments show that: when the officer conducting electrode joining reached 8%, then add the agent conduction, the battery of improving the power output is not produced visible results.

Talk about photovoltaic battery

Photovoltaic battery works:

Solar batteries through the photoelectric effect or photochemical effects of light energy into electrical energy directly to the camera. The photoelectric effect to work in thin film solar batteries solar for the general public, the working principle of photochemical effects of solar VGP-BPS9 batteries is still embryonic. Solar radiation in the pn junction semiconductors, the formation of new hole - electron pairs.

Photovoltaic batteries Introduction:

The solar photovoltaic batteries (PV batteries for short) are used for the sun’s light energy directly into electrical energy. Currently a large number of terrestrial PV systems based on silicon substrate using silicon solar batteries can be divided into monocrystalline silicon, polycrystalline silicon solar batteries in amorphous silicon. In the performance of energy conversion and the lifetime of an overall performance, monocrystalline silicon and polycrystalline silicon batteries are better than amorphous silicon batteries. Below conversion efficiency of polycrystalline silicon, but the price cheaper.

 

As required by the application after a certain combination of solar batteries to achieve a certain level of output and nominal output voltage of a group of photovoltaic VGP-BPS10 batteries, called PV modules. Depending on the size and scale photovoltaic power plants, a variety of PV modules can be composed of a variety of sizes.

 

PV modules using monocrystalline high-performance photovoltaic batteries or polycrystalline silicon, high transmission tempered glass, Tedlar, more corrosion resistant alloy chassis and other aluminum materials, the use of processes leading to vacuum lamination process and welding pulse. Even in the harshest environments can ensure a long life.

 

The installation of set up is very convenient. Components installed in the north watertight junction box, through which it can be easily connected with the external circuit. For each piece of solar Laptop battery components, are guaranteed over 20 years of life.
