Hitachi Zosen, development of all solid state lithium ion secondary battery
– superior in durability and safety compared with conventional lithium ion battery using liquid
All solid-state lithium-ion secondary batteries under development by Hitachi Zosen are superior in durability and safety as compared with lithium ion batteries using conventional liquid by solidifying the electrolyte filling between the positive electrode and the negative electrode, Overcoming the problem of liquid leakage and miniaturization, deterioration in performance in heat and cold and deterioration due to charge and discharge, which was a problem. Using the company’s press technology to form powdered materials into batteries, established technologies with performance equal to or higher than that of liquid batteries. It manufactures sample products with domestic battery manufacturers and also receives performance evaluation of Honda R & D Laboratories for EV. Bloomberg
