Development of positive electrode materials for low-cost and high-performance lithium-ion secondary batteries
Mitsuharu Tabuchi (Senior Researcher), Ionics Research Group, the Research Institute for Ubiquitous Energy Devices (Director: Tetsuhiko Kobayashi) of the National Institute of Advanced Industrial Science and Technology (AIST; President: Tamotsu Nomakuchi), has developed two types of new oxide material (namely, Li1+x(Fe0.3Mn0.7)1-xO2 and Li1+x(Fe0.3Mn0.5Ti0.2)1-xO2) for the positive electrode of lithium-ion secondary batteries in collaboration with Junji Akimoto (Leader), Crystal and Materials Processes Group, the Advanced Manufacturing Research Institute (Director: Nobumitsu Murayama) of AIST and Junichi Imaizumi (Manager), Technology Development Team 5, Technology Development Department of Tanaka Chemical Corporation (Tanaka Chemical; President: Tamotsu Tanaka). Approximately 30 % of the total amount of transition metals in these newly developed oxide materials is made up of iron, which is a low-cost and resource-wise abundant metal....
