In order to develop a new generation of electric cars, solar battery systems and other clean energy technologies, researchers need an effective way to store energy. There is a key energy storage devices for these applications and other applications, that is, super capacitors, also known as electric double layer capacitors.

Unique three-dimensional array of holes carved in the zeolite nano-carbon in the template so that it can be used as electrodes to fabricate high-performance super-capacitors, such capacitors have a high capacity and fast charge time .

In a recent study, scientists have investigated the possible use of a material that is called zeolite template carbon , can be used as electrodes for capacitors of this type, they found This unique porous structure of materials has greatly enhanced the overall performance of battery capacitor.

Researchers Hiroyuki Howard , West of the original Bo Friends , Tai Chi Kogure , Jing Gu Long from Japan Sendai Tohoku University, they have published results is a study of high-performance electric double layer capacitors, published in the latest Journal of the American Chemical Society .

Oak Ridge National Laboratory in the use of new technology, the relatively poor efficiency of a photoelectric conversion efficiency of solar cells increased by 80%, from 1.8% to 3.2%. Jun Xu’s research team created a three-dimensional cone-based solar cell platform to address the charge generated by the solar photon transport problems.

Defects in materials due to the battery, negative electrons and positive holes are trapped and lead to decreased conversion efficiency. The new technology can improve the charge collection efficiency. Using the same materials and new nano-cone structure of the conversion efficiency of solar battery more efficient than the traditional structure of 80%.

Many people fly with lighters and other items that can not, but you know, like computers, mobile phones etc. The lithium battery must be taken on board, there are many restrictions?

According to the provisions of the Civil Aviation Department to carry lithium batteries by air is limited. Containing lithium batteries to the personal use of consumer electronics devices (such as watches, calculators, cameras, mobile phones, portable computers, camcorders, etc.) and spare batteries can be placed in luggage to bring their own aircraft, or commissioned to assist the crew Treatment.

However, the number of spare batteries with the provisions of the civil aviation sector. Of which no more than 2g lithium content for lithium metal batteries and energy rating of not more than 100Wh, and the number of spare batteries required to meet the equipment standards for judging. For the nominal energy 100Wh to 160Wh large lithium-ion battery, approved by the airline, the number of spare batteries per person no more than 2 blocks. Devices containing lithium batteries may be placed in checked baggage or hand luggage, spare lithium batteries can only be placed in hand luggage.

Jiangsu coastal super wei company’s lead pollution report event, once a year last proof is merely a farce. And for super, super willy for Wisconsin battery for this incident more show leadership, they say will continue to rationally increasing performance action to eliminate the pollution image of lead-acid batteries. The traditional profession in the domestic for a very long time, have not been standardized management, so in reality, a lot of people take lead pollution comes down to me, because of lead-acid batteries lead acid battery industry consumes nearly 50% of the finished product lead.

But also understand people’s psychology, due to the traditional lead-acid batteries before entering the threshold is extremely low, so in the past years, China was born greatly small lead-acid batteries enterprise. But didn’t industry standard, most enterprise production process rather casual, for wastewater treatment had done almost consideration, causing serious pollution, so people lead mentioned lead pollution will be thought of lead acid battery, and this is super b&w suspected source of pollution. As China’s power battery leading enterprises, the production scale of lead-acid batteries is relatively large, was suspected of sensible.

Actually, battery production technology development so far, pollution control technology has also become increasingly perfect. Xiamen university majoring in chemistry professor Chen body bit pointed out that after continuous improvement, in use process of lead-acid batteries already won’t produce lead pollution, and manufacturing process control lead pollution is also can be done. Shandong university professor of chemistry and chemical engineering institute, said HuaShou south of lead-acid batteries already was the production process, according to the American statistical data, lead-acid batteries produced lead pollution industry already far less aviation industry, steel-making and boiler heating, power generation, etc. The name of the pollution of lead-acid batteries entirely from those non-standard little mill caused the production enterprise.

But those polluting of small and medium-sized enterprises at present the production has been largely containment, all over the country to shut in the scale of lead-acid batteries of poor small-scale production enterprise qualification. Only the most concentrated battery enterprises in zhejiang changxing, enterprise number has the original nearly 200 enterprises reduced 50 home. With the strength, cost of lead-acid batteries industry ongoing resources integration, like super wei such enterprise industry status, and to further consolidate these large enterprise will also lead acid battery industry out of China’s image and the pollution of themselves and shadow .
