Chinese lead-acid battery technology for electric vehicles Seminar was held in Long

The three-day China’s first electric vehicle lead-acid Digital Camcorder Battery technology training classes in the county has a successful conclusion. From the province hundred battery business executives and technical staff to attend the training, the Deputy Mayor Ding Quan concept of a training course graduation ceremony.

In recent years, with the popularity of China’s electric bicycle, electric bicycle with lead-acid battery production to an annual rate of 35% of rapid growth. In order to enable the battery manufacturer to acquire new technologies, adopt new technology, steadily improve product quality, Harbin Institute of Technology and Zhejiang Battery Industry Association co-sponsored by the Chinese lead-acid Digital Camera Battery technology for electric vehicle training classes.

After a county standard battery industry, the constant renovation has been formed from the raw and auxiliary materials storage battery manufacturing, battery assembly, vehicle production to waste battery recycling the whole industry chain, with a clear cluster advantage in the national battery market market share and industry influence in important, and to become the country’s green power supply production base.

Battery industry as the country’s leading experts, Harbin Institute of Technology professor, doctoral tutor SHI Peng-fei said that the Seminar will be held on the further development of the Casio Battery business will play a significant role in promoting.

New plastic solar cell conversion efficiency to create a world record

Wake Forest scientists at the University of the latest research results, enabling mankind to find solutions to the energy issues a big step, the school Nanotechnology and Molecular Materials Center, scientists will be the efficiency of plastic solar cells increased to more than 6%.

In the latest issue of “Applied Physics Letters” (Applied Physics Letters) will be published article, scientists describe how they achieve this record-breaking efficiency. Leaves by using a similar optical absorption lines of the plastic, they are made of nano-filaments. The Panel applied in Casio NP-100 battery thicker absorption layer, which can capture more sunlight.

As the price low, and very light, so efficient plastic solar cells are extremely desirable, especially when compared to traditional silicon solar cells. Traditional batteries are heavy and bulky, and can only receive 12% of light into electrical energy. Over the years scientists have been looking for curly, covering the flexible organic solar cells.

In 2005 years ago, plastic solar cells with maximum efficiency is only 3%, while after the Wake Forest nanotechnology center director David Carroll announced that they will increase that figure to 5%. Then about a year later, Carroll said his team beyond the 6% mark.

Carroll said: “In two years, we have to make efficiency more than doubled. I look forward to the next two years to achieve greater efficiency, make plastic devices to become truly one of the options.” In order to achieve commercialization requirements, must have at least 8% of solar energy into electricity. Wake Forest University team hope the next year to 10% efficiency.

As the folding, so plastic solar cells can replace roofing materials, and integrated into the wall. They also can be used in automotive, plastics batteries lighter, so no additional support equipment.

Canada “hydrogen-powered bicycle” is expected by the end of Sheung Casio NP-20

“Hydrogen-powered bicycle” – sounds like the future of technology. However, this bike at the end of this year will be in Canada or China may Sheung.

Horizon Fuel Cell Technology, Inc. founder Taras Wankewycz said that they have developed a bike, its power comes from hydrogen fuel cells, rather than ordinary rechargeable batteries. The company is currently working with officials in the negotiations between China and the Government of Canada to win the new bike coming year, Sheung.

Wankewycz said: “China has 10 million electric bikes a year to sell, the use of lead-acid batteries may be abandoned at any time.”

Horizon is also developing hydrogen-powered fishing boats, miniature cars, Casio NP-30 golf cars and toys.

At present, the hydrogen battery technology, there are still some problems to be resolved. First, the hydrogen production is more expensive, the production of hydrogen to create large quantities of carbon dioxide greenhouse gases. Although the chemical reaction, or solar energy can produce hydrogen cleanly, but their costs are very high. In addition, the hydrogen battery charging solar cell efficiency is not high.

Nevertheless, the hydrogen battery or the battery does not have other advantages: environmental protection; filling gas cylinders only takes a few minutes, while other electric vehicles to spend a few hours of charging.

Currently, fuel cell and hydrogen storage systems costly. Such as fuel prices of bicycles around 1000 U.S. dollars, of which the cost of power systems accounted for 600 dollars. In China, a lead-acid battery-powered electric bicycle prices generally 200 U.S. dollars. Therefore, the beginning of the new electric bike can only be sold to the bike rental companies and other corporate clients.

The high prices, making the new bike could not be with the general bike in the same breath. But the government’s requirement may make the new bike to be universal. Some cities in China and India have banned diesel two-wheelers Casio NP-40, Casio NP-L7 Sheung.
