Gree wants to acquire the news of Zhuhai Yinlong, the financial media of Zhuhai Yinlong, the lithium titanate battery of Zhuhai is fast charging in 6 minutes, the number of cycles is 30,000 times, and the life span is 30 years.


Do not think that Zhuhai Yinlong's lithium titanate battery technology is the best, how can the best technology be easily acquired by Gree?


There are three major lithium titanate battery manufacturers in China: Zhuhai Yinlong, Sichuan Xingneng, and Weihong Power. Among them, Zhuhai Yinlong's lithium titanate battery has the lowest energy density. Look at the comparison of the three.


Sichuan Xingneng lithium titanate battery energy density 200Wh / kg, bulk density 800Wh / L (data from its official website)


Yinlong lithium titanate battery has an energy density of 91Wh/kg and a bulk density of 182Wh/L (data from its official website)


The micro-power lithium titanate battery energy density is 85-110wh / kg (data from the article lithium titanate battery market heating?? Yinlong, micro-macro, etc. can counterattack?)


Why is Gree buying the worst lithium titanate battery factory? Because it is difficult to buy, it is difficult to buy, and then the investment will be greatly increased, and the technology can be pursued to improve the technical level. Gree spent 13 billion to buy a poor lithium titanate battery manufacturer. The lithium titanate battery is the development direction of the battery. The application of graphene in the battery has not been favored by experts. In fact, the lithium titanate battery and Graphene batteries can be quickly charged, but the cycle number of lithium titanate battery is 30,000 times, while the graphene battery is only 3,500 times, the energy density lithium titanate battery reaches 200Wh/kg, and the energy density of the graphene lithium battery and ordinary lithium Like batteries, graphene does not increase the energy density of lithium batteries. Dongxu Optoelectronics itself has admitted that the highest energy density of lithium batteries is only 150wh / kg.


The perspective of graphene lithium titanate battery cycles is much lower than lithium-ion batteries. The energy density is lower than that of titanate lithium-ion batteries basically have no continue to research and development value.
