Hitachi achieved a breakthrough in the design of a lithium-ion battery. The breakthrough will reduce production costs and extend battery life to 10 years.
Hitachi's researchers have proposed a new negative design that combines manganese and cobalt with other substances. The electrolyte in the battery has been improved to extend the battery's service life. Hitachi is studying other changes to the electrolyte to further extend battery life.
However, Hitachi says laptop and mobile phone users will not be the first to see this improvement, because Hitachi's focus is primarily on industrial-grade batteries and storage.
The new technology was developed by Hitachi in conjunction with the new energy and industrial technology development agency established by the Japanese government to invest in electricity research.
