Lithium battery with new capacitor

　　Relevant personnel learned from the press conference on the scientific and technological achievements of the "capacitive lithium-ion battery" held in Beijing that Chaoyang Liyuan New Energy Co., Ltd. has successfully developed the first batch of organic capacitive lithium-ion batteries in the world.

　　It is reported that this product can greatly improve the power characteristics, temperature characteristics, cycle life, charging and discharging speed, safety characteristics and other key performance indicators of traditional lithium-ion batteries, and play a positive role in solving the bottleneck problem that restricts the development of electric vehicles in China.

　　Yang Yusheng, an academician of the CAE Member, said that the capacitive lithium-ion battery independently developed by Liyuan is a combination of the working principle of super capacitor double electric layer and the working principle of lithium-ion battery embedding and de embedding to achieve complementary advantages, so as to meet the requirements of electric vehicles, electric special vehicles, electric engineering vehicles, heavy machinery and other power systems and energy storage systems in high energy density, high power density, high cycle life The urgent need for high security.

　　For many years, the development of electric vehicles in China has been hindered by the failure of power lithium batteries. The traditional lithium ion battery has high energy density, but low power density and short life; Although supercapacitor has the advantages of high power density and long life, its energy density is relatively small. The capacitive lithium-ion battery of Liyuan Company has both of the above advantages, realizing the complementary advantages of the high power, high cycle life, excellent temperature characteristics, safety performance of the supercapacitor and the high energy characteristics of the lithium-ion battery. Experts said that from the existing research and industrialization, the combination of supercapacitor and battery has become an important research direction in the field of energy storage devices. In the process of R&D, 35 national patents have been applied and 27 have been authorized.
