The Hyundai Motor vice President LiangXiongZhe said recently, Hyundai car has no intention of batch production electric cars in the future, will focus on the power to develop hybrid cars and hydrogen fuel cars battery.Hyundai car also decided that in the future the its kia by car is responsible for the production of the electric car.
LiangXiongZhe think, electric car battery technology has the reaching of the limit, its infrastructure push very difficult, it is difficult to replace the existing internal-combustion engine car, so should be as an alternative for motorcycle and electric bike models to research and development. Hydrogen fuel cell vehicles on the development of new technology, the company has now by Mercedes, but modern car in recent 10 years has been in the field have faith in investment, hydrogen fuel battery field contribute.

Ohio, USA Nanotek Instruments researchers have used lithium ion electrode in the graphene surface and a large number of shuttling between the rapid movement of features to develop a new energy storage device, the charging time can be from the past several hours down to less than a minute. The study published recently in the “Nano Letters” on.
Present mainly in battery technology is lithium battery and super capacitor technology, lithium battery and super capacitor mixed. Lithium-ion battery energy storage density, 120 W / kg to 150 W / kg, the super capacitor energy storage density is low, 5 W / kg. However, low-power density lithium batteries, to 1 kW / kg, while the super-capacitor power density of 10 kW / kg. Currently much research work has focused on improving the power density of lithium-ion battery or super capacitor energy storage to increase the density of these two areas, but the challenge is enormous.
New energy storage devices, also known as graphene surface lithium-ion replacement battery, or referred to as surface-mediated cell (SMCS), which focused on the advantages of lithium batteries and super capacitors, while both high power density and high energy storage density of features . Although the energy storage device is not used to optimize the materials and structures, but the performance has exceeded the lithium-ion batteries and super capacitors

According to the U.S. “Popular Science” Web site reported that the United States a 13-year-old boy beaten track, to the trees as prototypes invented a new type of solar battery panels, energy efficiency than traditional solar panels more than 50%.
The 13-year-old boy who lives in New York this year, Aidan Dwyer junior high schools. Last year, the depths of winter hiking trip to the mountains, Aidan inadvertently noticed very regular distribution of branches of trees, tree branches and immediately concluded that according to the Fibonacci mathematical sequence arrangement.
Aidan think this is necessarily related with photosynthesis, trees, and began to boldly experiment. First, he produced their own design with a cylindrical double-oblique protractor measure the distribution ratio of spiral foliage of trees. After that, he will be the proportion being copied to the computer program and create a control with a PVC solar battery shaped like oak group.

According to Kyodo News agency reported that Japanese research firm Techno Systems Research1 announced the second quarter of 2011 worldwide shipments of lithium-ion batteries show that the share of South Korean companies has surpassed Japan for the first time ranked first. East Japan earthquake caused the biggest reason for the Japanese manufacturers cut production.
Sanyo Electric, Sony and other Japanese manufacturers share, compared with the previous quarter, down 4.3 percentage points to 33.7%. Samsung SDI and LG Chem and other South Korean companies are jumped up to 42.6%.
Sub-brand watch, Samsung SDI ranked first with 25.3%, significantly ahead of second place Sanyo (18.4%).
Lithium-ion batteries for mobile phones and other popular demand, the share of Japanese manufacturers fell for a large earthquake.

University of Southern California scientists have developed a safe, effective method to extract and store hydrogen for fuel battery, promote the use of hydrogen to remove the obstacles. Research published in the new issue of “American Chemical Society’s Journal”.
Responsible for developing the technology, Associate Professor University of Southern California Travis Williams said: “We have found a way to grab and store the hydrogen chemical method This method can be done to extract ammonia borane from the gaseous hydrogen, and then gaseous hydrogen into ammonia borane to store the complete process, which is made in the field of hydrogen storage breakthrough has practical significance. ”
Hydrogen is an important fuel, hydrogen fuel cell easily converted into electricity, and does not emit carbon dioxide. But as gas, hydrogen can only be stored in high pressure or low temperature container.
Associate Professor University of Southern California, said Travis Williams, improper storage of hydrogen will be a huge risk. If you enter a scene, which is full of hydrogen vehicles within the jar, then it will be a very dangerous thing. One solution is to use a safe chemical hydrogen form of storage. Earlier this year, Williams and colleagues found a way to use a harmless chemicals - nitrogen - boron compounds, ammonia borane complex as a hydrogen source, allowed the release of hydrogen, ammonia borane complex can be stored in a stable solid form.

Batteries usually can be used for 3 to 5 years. Life expectancy depends on many factors, including the use of (equipment must be in the number of battery-powered mode), and other environmental factors. Here are some of your equipment to ensure optimum use of the principle of life expectancy:
1 Make sure your APC UPS placed in a cool, dry and ventilated place. Ideally, UPS placed where the temperature should not exceed 24 degrees Celsius. Meanwhile, for ventilation purposes, are set aside on each side about 1-2 inches of space for air ventilation.
2 year only if necessary 1 to 2 times a UPS runtime calibration. Sometimes, you can run your run-time calibration to verify whether the running time is sufficient. However, frequently perform run-time calibration will reduce the APC battery life expectancy.
3. Do not store the APC battery long time. New batteries can be stored for 6-12 months. After this time, they should use the battery as soon as possible, otherwise it will lose its large storage capacity. Not recommended for storage of used batteries.
4 Do not over load the UPS rated capacity of 80%, as this will result in reduced run time. Load increases, the running time will be reduced accordingly. If the power can not supply full load of the UPS will soon run out and release the battery power, this will reduce battery life expectancy. Note: To ensure longer battery run time, do the laser printer connected to the UPS battery backup outlets. To ensure that laser printers use the “Surge only” outlet (using the appropriate model). For those who do not “Surge only” outlet of the UPS, recommended laser printer connected to a separate APC surge suppressor.
