Nanguang New Energy try to produce Lithium Battery ,Lithium Battery Special Carbon Negative Material is born.

15 Corda coal chemistry research institute learned that a high-capacity high-density lithium battery with pure carbon as the main component of the special carbon negative material was introduced in the hospital, the current, new electric vehicle lithium battery based on this material has been Chengdu Nanguang New Energy Company official trial production.

It is understood that in the power system of new energy electric vehicles, the capacity of lithium batteries(ie, the energy density of battery cells) depends entirely on the composition of lithium ion battery negative electrode materials. Dr Liuchangguo, chief engineer of Chengdu Nanguangxin Energy Company and inventor of the first new energy car lithium battery in China, said that since the localization of lithium batteries, negative materials have been mainly composed of natural graphite, with long charging time and low single capacity density. As a result, the range of new energy vehicles in our country is difficult to break the 300 km limit. From the experimental data and product performance test, this lithium battery prepared from all new materials can achieve a mileage of more than 600 kilometers.

The technology inventor and general manager of Yulin Kodak Coal Chemical Research Institute Co., Ltd., Hefeng, said that the energy storage materials of the new single battery have abandoned the traditional natural graphite in research and development, and pure carbon has been made into high-capacity and high-density lithium battery negative materials through physical and chemical methods.

Experiments have shown that this new negative material has a gram capacity of 2,200 mAh/g, a negative plate compaction density of more than 2.0 g/cm3, and a positive electrode with triplet material plus lithium cobalt. The mass energy density of a lithium battery can exceed 350 W/kg. "In addition, lithium batteries based on new materials do not take more than 15 minutes to charge, which is beyond the reach of conventional batteries. After testing, the temperature of the new material battery is always at room temperature during charging and use. " said Hefeng.

Liuchangguo said domestic experts in the field of new energy power batteries had expressed concern about whether domestic lithium batteries could achieve a single energy density of 350 Wh / kg by 2020, and the new batteries being tested have surpassed this goal.
