Smart Energy revealed that 220Wh / kg ternary batteries have been mass-produced

Recently, smart energy held a meeting of investors to communicate on the main issues of concern to investors. Among them, in the power battery business, smart energy revealed that the 18650 ternary battery with an energy density of 220 Wh / kg has been mass-produced, and the system energy density has reached 140 Wh / kg; It is expected that most of the two rounds of markets will use cylindrical lithium batteries such as 18650 and 21700.

The company will continue to build a battery industry with a total capacity of over 12 GWh, including cylindrical batteries, soft package cores and square aluminum shell lithium batteries, in Yichun, Jiangxi Province and Yixing, Jiangsu Province this year, according to smart energy. It also reached a strategic cooperation agreement with Nanshi, a lithium carbonate producer established in Yichun, which has the largest reserves of lithium mica in China. Nanshi plans to have a capacity of 60,000 tons of lithium carbonate in 2020, effectively ensuring the supply of raw materials for upstream batteries. In addition, this year, the company will also expand its development in the digital, two-wheeled, low-speed four-wheeler, especially the first-line brand car market.

Based on the production capacity layout of Zigongsiyuandongfusite's 21700 battery, Smart Energy established Far East Foster New Energy Jiangsu Co., Ltd., settled in Yixing Smart Energy Industrial Park in Jiangsu Province, planning more than 1,000 acres of land, and will invest 5 billion yuan to build China's leading and world-class automation. Intelligent soft package core and square aluminum shell lithium battery production base. The first phase of the project was inaugurated in the third quarter of 2017 and is expected to reach production by the end of December 2018.

Yuandongfusite is the leader of the domestic three-yuan 18650 lithium battery and is now upgrading to a new 21700 battery manufacturer. Technically, smart energy improves the single core capacity by improving the performance of positive-negative materials, adopting lightweight materials, and structural optimization, resulting in a single core energy density of more than 220 W/kg. At present, the 220Wh / kg 18650 ternary battery has been mass-produced, and the energy density of the system has reached 140Wh / kg through lightweight design.

Smart Energy also stated that due to the advantages of cylindrical lithium batteries in terms of technology, economy, and preservation, it is expected that most of the two rounds of markets will use cylindrical lithium batteries such as 18650 and 21700.
