Nissan has introduced a lot of electric vehicle such as BEV to the market to become ZEV leadership.In the electric vehicle, Li-ion batteries is regarded as key component in determining the vehicle performance and cost, and we have been carrying out battery research for many years. For automobile use, the Li-ion battery are required to achieve high level balance between energy density, power density and environmental robustness, and for this purpose, an approach based on a fundamental understandings such as numerical modeling, diagnostic technology and material science are important. In this speech, our fundamental research on Li-ion battery and expectations to future battery system will be introduced.
