Rechargeable notebook batteries could explode

Rechargeable notebook batteries could explode

With simple maintenance procedures, notebook battery the cost of re-work cost only one-eighth of the purchase of new batteries. Yesterday, the reporter visited the Zhongguancun learned the insider sales. Professionals to remind consumers that this kind of “core exchange” battery There is a certain security risk.

Vote in the country and in the sea of electronic markets, to engage in second-hand notebook business transactions are that they can provide such as “for the core” of maintenance services. IBM600E as an example to the original battery, “for the core” cost about 300-400 yuan, and its process is very simple, just have a basic spot welding equipment and technology can be completed. In the repair site, the repair personnel to break open the original battery, will the old batteries (similar to common rechargeable batteries) out, and then as it will be in accordance with the new batteries will be followed by spot welding to connect the success of the whole when there is no more than 30 minutes. “In fact, most of the laptop dell battery, dell inspiron e1505 battery can not recharge batteries as a result of aging are caused by the battery as long as the control board did not let the bad, the maintenance of nearly 100% success rate.” The businessmen explained that the business also revealed that At present, batteries are in circulation are from the South to buy large quantities. Electronic market in the South, “for the core,” has long been no secret, just before the beginning of this year a large number of emerging electronic markets in Beijing, but also popular. “In the ‘Blue Express’ where to buy a piece of the price of a new battery at least 1,000 yuan more than that many clients are it’s cheaper to come.”

“Blue Express” the technical staff, told reporters that private “for the core,” there is a big security risk, some testing batteries without charge even after the bursting of short-circuit phenomenon, ranging from damage to the host, then re-explosion .

A staff member confirmed that the purchase of new 600E battery takes about 2,400 yuan. The difference between the prices, “Blue Express” the Propaganda Department of the Miss Yu said, IBM has its own pricing strategy worldwide, the company did not modify the permissions, and whether the choice to repair the battery is the client’s freedom.

Microbial fuel cell

Microbial fuel cell

Since the industrial revolution, has been plagued sewage treatment in developed and developing countries a major problem-laptop battery, because it expensive, is only of inputs, not outputs of the industry. And new microbial fuel cell can not only purify the water, but also for power generation, the emergence of its sewage treatment is expected to become a profitable industry. Although still in the continuous improvement of the product has not yet put into commercial production, but we have every reason to believe it has broad prospects for development.

Recently, by the United States Pennsylvania State University scientists, led by Logan, a research and development team announced that they have developed a new type of microbial fuel cell can be of untreated sewage into clean water and power.

Microbial fuel cell (MicrobiologicalFuelCells) there is not just a technology. As early as 1910, the British botanist discovered for the first time Mark bits of bacteria in culture medium to produce current, therefore, he made use of platinum electrodes, put it into E. coli and general yeast culture medium-dell battery, the successful production of a the world’s first microbial fuel cell; in 1984, the United States to create a space for use in microbial fuel cell, which fuel for the astronauts of the urine and live bacteria, but it’s a very low discharge rate; In recent years, the use of Microbial generation of technology breakthroughs have emerged more, Pennsylvania State University environmental engineering professor Bruce Logan is a new microbial fuel cell development team, he said, “the traditional is the use of hydrogen fuel cell power generation, but no one try to use organic-rich water to generate electricity. ”

A major innovation: a single slot design

Logan designed the battery and hydrogen fuel cell device to be somewhat similar, is a sealed cylindrical glass tank of resin, looks like a soda bottle. And hydrogen fuel cells, however different, the microbial fuel cell is a single reaction tank, containing eight graphite anode rod, and they stick around a cathode, confined to the middle slot between proton exchange membrane. Confined to the external tank of the closed circuit composed of copper, used for electronic flow path. When water was injected into reaction tank, the bacterial enzyme to break down organic matter in sewage, in the process of releasing electrons and protons. Among them, the electronic flow of the anode, and protons through the proton exchange membrane inside the flow of anode, where oxygen and air as well as the electronic generation of clean water combined. Thus completion of the sewage disposal. At the same time, the reaction bed is the electronic exchange between the cathode produced a voltage, so that the equipment can supply to the external circuit.

Reaction is a single slot design of microbial fuel cell innovation. Logan pointed out that most of the design of fuel cell response to the two slot-oriented — were anode and cathode slot slot, slot in the anode in order to maintain anaerobic microbial growth; cathode tank should be maintained at aerobic environment to enable electronic and oxygen combine with protons to form water molecules. And a single reaction tank in order to proton exchange membrane to link the two slot, and its function not only in aqueous solution can be divided into two slots, but also to avoid spread to another tank of oxygen. Electrobath trough of the two, other than the force required to provide dissolved oxygen to the cathode, and a single tank of fuel cell micro-organisms can be the way to continuous injection of air into the cathode, thereby reducing the cost of oxygen equipment.

Samples will be completed six months after

In generating capacity, according to Logan said, in the laboratory, the device can generate 72 kilowatts of current, you can drive a small fan. Although the current generated by small, but the equipment is much room for improvement. Invention from the report submitted to the present, Logan’s R & D team has the fuel cell power generation capacity to 350 watts, but Logan would like this value to achieve the ultimate 500-1000 watts. Such as maturity of the technology can be mass-produced microbial fuel cell power generation capacity will be greatly improved, and Logan believes that it can generate 500 kilowatts of the stability of current, about 300 family’s electricity consumption. Logan plans to build a large-scale microbial fuel cell sample, is expected to be completed six months later.

Application prospects

Although the device’s energy output is relatively low, but Logan said they are continually improving the technology, I believe that it can be used in small-scale sewage treatment factory. It is said that the device can also be used to deal with livestock waste water and waste plants, but also can be used in food-processing plants and even manned space inside.

Logan pointed out that as long as it is a place rich in organic matter can be the use of such dell inspiron 600m battery, dell latitude d500 battery. However, the microbial fuel cell is the best use of sewage treatment, sewage treatment plant if the use of such equipment, so they can waste water treatment side of the side of power generation, and thus greatly reduce the cost of sewage treatment. Wastewater treatment plant to maintain the normal operation is a very high cost of things. Both developing countries and industrialized countries, wastewater treatment at the same time, the new generation fuel cell technology is very attractive. According to statistics of the U.S. National Development Committee, the United States need to address each of the 33 billion gallons of domestic sewage, the treatment cost about 25 billion U.S. dollars. Most of the cost of almost all spent on the maintenance of treatment plant operation of the energy required, so that if the microbial fuel cell can reduce costs and improve efficiency of electricity generation will be a huge savings for the wastewater treatment expenses.

For the majority of serious pollution of the developing countries, this technology is particularly useful because it can not only purify the water quality, disposal of refuse, while the power generated. Separate from the power this context, the Government has sufficient reason to retain the building and a sewage treatment plant. If the technology can promote the commercialization, waste or sewage treatment will be the country’s money-spinner rather than a heavy burden.

University of Toronto is a scientist, he estimated the energy potential in wastewater is 10 times the cost of processing. Logan believes that as long as they can use the potential power of 1 / 20, a sewage treatment plant can be resolved on the cost of sewage treatment.

Microbial fuel cell can also be used to deal with food-processing plants and farms, especially pig farms in the wastewater, in the past, to deal with these unpleasant stench of sewage expensive. NASA also is developing a similar technology, manned space flight in astronauts living in the garbage into energy.

Sony liquid crystal display speed charger experience

Sony liquid crystal display speed charger experience

As the market brand rechargeable batteries and chargers messy, mixed, consumer products also do not know much about technology, it is prone to blindly purchase price or even to measure only the phenomenon of choice. Recently, I have to buy liquid crystal display Chargers (Super Quick Charger with LCD) there are good things and we naturally want to share a piece has been fuss even today-laptop battery, finally finishing it up, we hope that they will be charging equipment in the selection of some small revelation. The appearance of this charger with a “beautiful” to describe is not excessive, the “11″ to bring it out, it is a good feeling. Weighing only 110 grams of chargers, and are offered in compact form, it seems on the bags can be ignored. Sony LCD new charger on the domestic market is currently the only state-of-charge function liquid crystal display products, this unique feature allows the user-friendly products Sony has once again proven advantages.

The charger is a clamshell design, the look is not only beautiful, but also, cover the exposed cells, in time to carry out, in addition to moisture can dust it waterproof shockproof. Moreover, It is said that in the event of an accident such circumstances, can effectively reduce the extent of the harm people. Charger with other difference is that the bottom of the clamshell has a LCD screen, thought it is just window dressing decoration, never thought it a good “intelligence”, the charger has an orange backlit LCD screen, even in the dark can also be easy to see, regardless of charge or discharge can be displayed on the screen. Very sensitive to the heavy travel, and as a digital essential accessories, charger package should have all the equipment to meet the supply capacity of the charge. According to experience some of the previous discovery, or to use the original package and battery chargers, chargers suit for their support of a good brand of battery, charging effect, and maintenance of batteries and more to help. Poor quality of the charger, it will not only accelerate the aging batteries, and use of low-grade rechargeable dell battery charger, it will cause damage to electrical equipment. Therefore, from this point is important.

Sony LCD charger with the greatest degree of compatibility and ease of use, very inclusive, to Paul and I travel in the demand for electricity, and easy to use. At the same time, it on the 5th and the 7th for charging rechargeable batteries and battery on the 7th position is independent, to ensure good contact. Digital equipment so that I have adequate access to the electricity.

Travel the least and endure long hours of charging, and so will miss a lot of good scenery, and may also result in regret. I think the choice of the Chargers the most important factor is to look at the speed of its charge, so I have to choose smart rapid charger. General quality of the market the brand better able to do six hours to complete the charge, while the Sony LCD charger speed charger with two hours to two full-capacity 2100mAh battery on the 5th, 4 hours 4 full, if it is on the 7th of 800mAh battery, it only needs one hours and at such a pace on the road can meet the demand, and want to make the shot.

Of course, a good rechargeable batteries but also more time to meet the needs of the application, if the fast charge time, continuing the time lost by the wayside quickly, then on the. We know from the packaging of rechargeable batteries can see “xxx mAh” such a standard code, which is battery power, td347 battery capacity can indicate the size, the greater the value, the longer durability. Typically 2100 mAh Ni-MH battery has sufficient capacity to meet the demand of the. Sony LCD Speed Charger is equipped with four of the 2100mAh capacity for AA (5 #) batteries, from the capacity and reliability of brand point of view, are an excellent choice.

Usually we are not fully aware of all battery depletion charge on the circumstances, and in fact there is often remaining battery power, which after repeated use, rechargeable battery memory effect can occur as a result of available capacity to reduce the phenomenon, according to the report the relevant information, which will reduce the battery power to support the reduction in the number of photographs of about 13%. To solve this problem is in the best way to recharge before the batteries discharge, so that there is no battery power remaining after charge. Sony LCD new speed charger on with such a function, discharge function, but can also be displayed in the LCD screen on the case of a discharge.

The protection of the battery the most important thing is to prevent over-charging, if the charger can not provide protection in this area, we had no choice but to use the timer to control the charging time, in estimating the power to artificially stop after a charge, but usually can not be easily the notes, but also difficult to control, if not careful will cause battery explosion occurred, I have been looking forward to have an automatic monitoring of the charge, after all, you safety first.

Sony liquid crystal display speed charger with voltage detection device that can automatically complete the power-off charge, to avoid over-charging, when the charge temperature anomalies, the protection circuit will automatically cut off power to prevent accidents. Not always as it was before the charge to be concerned about the time, so that the battery will be able to automatic protection.

NDS compatible with GBA SP console dedicated lithium-ion battery

A few days ago a well-known IT hardware network ‘Lik Sang’ for the Nintendo DS battery made a comprehensive evaluation that will be compatible with NDS host a special GBA SP Li-ion battery, attached to the 3 pictures to show contrast, we can see the special lithium dell latitude d610 battery and dell gd761 battery NDS interface with the GBA SP Li-ion battery interface is basically the same, and have to buy a GBA SP and NDS players can purchase back-up battery to save a sum of money, Nintendo in this regard is quite user-friendly design.

Will lose something, some unscrupulous traders already making a greater profit for the renovation of the old GBA SP battery to sell new, I believe that this phenomenon will also appear in the NDS.
