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 1.1 is a 5-year fundamental research type project (2016—2020) with a 32M￥ budget，aiming to increase the energy density of EV batteries. Two targets are purposed: 400 W•h/kg for Li-ion batteries and 500 W•h/kg for new batteries. After 3 rounds review and defense, a team led by Institute of Physics, CAS wins the project. The title of the project is “High energy density lithium batteries for long range EV”. Scientific problems and technologies of three types batteries will be studied: 400 W•h/kg lithium ion batteries, 500 W•h/kg half-solid Li-S batteries and 600 W•h/kg solid Li-air batteries. This project includes 11 CAS institutes and one company BJEV as partners.

Key words: high energy density Li-ion batteries, half-solid Li-S batteries, solid-state Li-air batteries, electric vehicles
