Chuangyuntian and Yinlong jointly developed lithium nickel-manganese acid batteries，which is expected to be launched in the second half of the year

Recent news shows that Shenzhen Jichuangyuntian New Energy Co., Ltd.(hereinafter referred to as "Jichuangyuntian New Energy") and Yinlong New Energy Co., Ltd.(hereinafter referred to as "Yinlong") signed a strategic cooperation agreement, and the two sides are committed to the industrial chain. All aspects of comprehensive cooperation.

Among them, the two sides have taken the lead in setting up a joint research institute on the development and production of a new generation of lithium nickel-manganese acid batteries, and have carried out in-depth cooperation in technical research and development, information sharing, and personnel training. Major breakthroughs have been made in key technologies for lithium nickel-manganese and lithium nickel-manganese manganese and graphite batteries. The new generation of lithium-ni-manganate batteries is expected to be available in the second half of this year, with larger capacity, faster charging, wider temperature resistance, higher safety, longer service life and lower cost.

According to the data, Jichuangyuntian New Energy Co., Ltd.(hereinafter referred to as "Jichuangyuntian New Materials"). In October 2017, the new generation of Lithium Nickel-Manganese Battery Positive Materials Project, which was invested and constructed by Gaodianya and Hong 'an County, was officially started in Hong' an County. The total investment of the project is 650 million yuan, and it plans to build six automatic production lines for new energy materials. The first production line will be completed and put into production by the middle of this year.

It is worth mentioning that the force on the lithium nickel manganese acid material is not only the collection of Yuntian new materials, but also Chengdu Xingeng. It is understood that the high-potential and long-life positive material lithium nickel-manganate developed by Sichuan Xingneng New Materials Co., Ltd., a subsidiary of Chengdu Xingneng, passed the scientific and technological achievement appraisal organized by the Sichuan Provincial Office of Science and Technology in 2013. The scientific and technological achievements reached the international leading level. Get 1 million yuan in funding support. The material has now been industrialized, and the company has an annual production capacity of 1,000 tons of Gaodianya.

However, it is easy to achieve mass production of lithium nickel-manganese acid materials, and it is difficult to realize the industrialization of lithium nickel-manganese acid batteries.

lithium titanate batteries made of lithium nickel manganese as a positive electrode have a higher energy density and lower cost than lithium titanate batteries, according to one industry insider. However, the voltage is relatively high when applied, 4.7-4 .9 V when charging, and 5.2 V when full. This requires a new material system, especially new electrolytes and diaphragm.

Therefore, although the lithium nickel-manganese acid material has a relatively stable spinel structure and is currently capable of mass production, the mature Gaodianya electrolyte that is used in conjunction with it has not yet been developed on the market, which has affected the market application of lithium nickel-manganese acid by Gaodianya..

Fan Weifeng of Chengdu Xingneng New Materials Co., Ltd. told Gaogong Lithium that at present, Chengdu Xingneng has achieved the mass production of Gaodianya, and at the same time has conducted experimental verification studies with different negative electrode materials. This product will become the company's future. The key development products in the years.

It is good news for the lithium ion battery industry to set up a joint research institute to accelerate the process of research and industrialization. How to overcome the problem of imperfect supporting materials, and when the lithium nickel-manganese acid battery can be applied on a large scale, high-grade lithium will continue to track the report.
