The new battery has a decay of less than 10% in 6 years, and the bus is charged by more than 60% in 8 minutes

Currently, for electric vehicles, the biggest limiting factor is still the battery. And if the battery can solve the disadvantages of slow charging speed, short battery life, and degraded charge and discharge performance, the popularity of electric vehicles will also be greatly accelerated. According to CCTV Finance and Economics, during the '13th Five-Year Plan' period, my country's new energy vehicles have shown an explosive rise. At the same time, my country has also continued to send good news in the core technology of new energy batteries. With his team, he developed a new type of battery material. Chen Liquan, an 80-year-old academician of the Chinese Academy of Engineering, is the founder of my country’s lithium battery industry. In 1996, he led a scientific research team to develop lithium-ion batteries first in China, and took the lead in solving the scientific, technological and engineering problems of the large-scale production of lithium-ion batteries in China. Industrialization of domestic lithium-ion batteries. In Liyang, Jiangsu, Li Hong, a protégé of Academician Chen Liquan, led the team to achieve a breakthrough in a key raw material for lithium-ion batteries after more than 20 years of technical research, and mass production was carried out in 2017. According to reports, the Institute of Physics of the Chinese Academy of Sciences has been researching nano-silicon since 1996. The nano-silicon anode material is a new material they independently developed. The button battery made from it has 5 times the capacity of traditional graphite lithium-ion batteries. At the same time, the new solid-state battery developed by Professor Li Hong and the drone using this battery will increase the battery life by 20%. The mystery lies in the solid-state cathode material of this battery. In 2018, the design and development of a 300Wh/kg solid-state power lithium battery system has been completed here. After being installed on the vehicle, it can double the mileage of the vehicle. In May of this year, such solid-state batteries have begun to be used in consumer electronic products. In addition, not only the Institute of Physics of the Chinese Academy of Sciences, but many companies are also exploring new energy battery technologies and new materials. At Yinlong New Energy Energy Storage System Research Institute in Zhuhai, Guangdong, a pure electric bus is being charged. According to the engineer, the bus equipped with lithium titanate battery charged for three minutes, and the power was charged from 33% to more than 60%. In just 8 minutes, the bus was fully charged and the power level showed 99%. Moreover, the bus line is fixed. Generally, the number of kilometers for a round trip will not exceed 100 kilometers. By using the neutral position of the bus driver to rest, the advantage of fast charging of lithium titanate battery can be fully utilized. And the working temperature is wide, in the environment of minus 50 ℃, it can still charge and discharge normally. At the same time, the battery has a long cycle and discharge life. This research institute has a lithium titanate battery that has been charged and discharged cycle tests since 2014. Now it has been six years and has been charged and discharged more than 30,000 times. The battery capacity has only decayed by less than 10%, and the performance is very excellent. What is more noteworthy is that the thermal runaway protection performance of this battery is even more amazing. The technicians demonstrated the drop, acupuncture and cutting tests of the lithium titanate battery on site. Especially after the steel needle pierced the battery, there was no burning or smoking, and the battery could still be used normally. However, although the lithium titanate battery has so many advantages, the energy density is not high enough, only about half of the lithium ion battery. Therefore, they divided the battery's target market into application scenarios that do not require high energy density, such as buses, special vehicles, and energy storage power stations.
