Yinlong New Energy settled in Chengdu in order to overcome five major problems

Peak recently experienced a job transfer. He came to Chengdu Xinjin County from Hebei Handan and served as the dean of Yinlong New Energy Chengdu Industrial Park Battery Technology Research Institute. This research institute, which was established on May 4, is the largest new energy battery production base among the eight major bases in the country for the layout of Yinlong New Energy. The research and development direction mainly includes lithium titanate batteries, ternary batteries, titanium iron lithium batteries, ternary Silicon carbon cells, solid electrolyte cells, and fuel cells. At present, under the same volume, lithium titanate batteries have achieved R&D and mass production from 25Ah capacity to 40Ah capacity. In the future, more "Chengdu made" new energy batteries will be sold around the world.

There will be more than 600 full-time researchers

Driving from Chengya Expressway, about 28 kilometers later, you can reach Yinlong New Energy Chengdu Industrial Park. After entering from the dark red gate, the first thing to see is the office building and advanced production workshop. It is also home to Yinlong New Energy Chengdu Industrial Park Battery Technology Research Institute. The existing office buildings and factories are selected as the basis for planning. The office buildings, R&D centers and laboratories cover a total area of about 16,000 square meters, focusing on the development of a new generation of high-safety, high-performance and low-cost lithium-ion batteries and new system batteries. Meet the requirements of the new energy field for battery high specific capacity, long cycle life, wide operating temperature range, rapid charging and discharge, high safety and environmental protection, and successfully applied to new energy fields such as electric vehicles and energy storage systems.

At about 9 o'clock in the morning, the peak reached the R&D center on time. More than 100 technicians are nervously organizing data, revising drawings, and testing samples. The high-end technical talents in the field of new energy batteries like the peak are being "assembled" from all over the country. Chengdu, "At present, Dozens of people have been brought from Handan Base. In the near future, there will be more than 600 full-time researchers here, and more than 60 undergraduate degrees. Master's degree accounts for more than 15 %. Some foreign experts are also included. "

"The products developed by the Institute will be sold around the world, in addition to supplying other bases across the country," Gao told Chengdu Evening News. In the future, there will be more 'Chengdu made' new energy batteries in everyone's view. "

Research and development technology to overcome the world's five major problems

When it comes to the direction of research and development, the most proud of the peak is the lithium titanate battery used for buses. "Although this battery is ordinary in appearance, we have overcome the five world problems recognized in the industry: safety, wide temperature, rapid charging and discharging, life span, and industrialization." According to him, due to the stable structure of lithium titanate, the surface does not form a solid-liquid interface passivation film, and the dynamic properties can still remain at room temperature at low temperatures. The reaction activity between lithium titanate and electrolyte is low, which improves the stability and safety of the battery. At very high temperatures, lithium titanate absorbs oxygen produced by positive decomposition, reducing the risk of thermal runaway and improving the safety of the battery.

Not only that, but based on lithium titanate batteries, they can be quickly charged and discharged, and can be used on buses to carry out random charging. You can use the bus to reach the terminal driver's rest time(10-20 minutes) to quickly recharge the battery. "It can achieve 6 minutes of fast charging and up to 25,000 cycles. "The goal of lithium titanate batteries this year is to achieve the development and mass production of 45Ah capacity, and the increase in energy density means that the mileage of buses has been improved," said Feng.
