Nissan develops world first analysis technique for better li-ion battery durability » Automotive World

Can the battery performance of electric vehicles be improved by observing electrons? Nissan sought an answer to this question through an advanced research project in partnership with universities in Japan. The result: Nissan Motor Company and its affiliate Nissan Arc Ltd. today announced the development of the world’s first analysis method that enables direct observation of electron activity in the cathode material of lithium ion batteries during charging and discharging. Applying this analysis technique to future research and design of battery materials could enable Nissan researchers to develop high-capacity and high-durability batteries that may extend the driving distance of zero emission EVs and improve their durability.

Nissan Arc Ltd., a 100-percent subsidiary of Nissan Motor Company, developed the analysis method in a joint R&D effort with Tokyo University, Kyoto University and Osaka Prefecture University. The newly-developed technique provides an accurate depiction of how electrons are emitted from certain elements that constitute the cathode material of lithium ion batteries when charging and discharging.
