Nanguang New Energy Trial Production Lithium Battery, Lithium Battery Special Carbon Negative Material

It is understood that in the power system of new energy electric vehicles, the capacity of lithium battery (that is, the energy density of battery monomer), completely depends on the composition of lithium ion battery cathode material synthesis. The first piece of new energy vehicles in China lithium battery inventor, chengdu nanguang new energy company chief engineer, said Dr Liu Changguo localization of lithium-ion batteries, natural graphite anode materials have been as main ingredients, charging time is long, the density of single capacity low technology bottleneck, cause of China's new energy vehicles 300 km range difficult to break the limit. According to the experimental data and product performance tests, the lithium battery made of new materials can achieve a range of more than 600 kilometers.

He feng, general manager of yulin keda coal chemical research institute co., LTD., the inventor of the technology, said that the energy storage material of the new single battery abandoned the traditional natural graphite in research and development, and made pure carbon into high-capacity and high-density lithium battery cathode material by physical and chemical methods.

The experimental results show that the new cathode material has a capacity of up to 2200mAh/g in grams, and the compacted density of the anode sheet exceeds 2. The mass energy density of lithium battery can exceed 350Wh/kg. "In addition, a lithium battery based on the new material takes less than 15 minutes to charge, which is beyond the reach of conventional batteries. After tests, the new material battery charging and use process, the temperature is always room temperature. Martin ho said.

According to liu, experts in the field of domestic new-energy power batteries have expressed concerns about whether domestic lithium batteries can achieve a single energy density of 350Wh/kg by 2020, and the new battery in trial production has surpassed this goal.
