Abstract: Ministry of Science and Technology of the People’s Republic of China (MOST) initiates national new energy vehicles pilot project in 2015 for next 5 years. Totally 19 projects are announced in 2016. The project 1.2 is a 5-year fundamental research type project (2016—2020), aiming to increase the energy density of EV batteries and to promote the batteries into EV market further. Two targets are purposed: 300 W•h/kg for Li-ion batteries and more than 1000 EVs using the batteries in the market. After 3 rounds review and defense, a team led by Hefei Guoxuan High-tech Power Energy Co. Ltd. wins the project. The title of the project is “Development and Application of Lithium ion Batteries with High Specific Energy Density”. Scientific problems and technologies will be studied: system matching of high nickel cathode and Si-based anode to achieve more than 300 W•h/kg energy density with >1500 cycle life, multilevel security protection of the batteries during integrated application in EVs. This project includes 6 institutes and 6 companies as partners.

Key words: high energy density Li-ion batteries, 300 W•h/kg, multilevel security protection
