Japan uses titanium as a battery material to reduce the cost density

So far, in the development of high-performance batteries, cerium oxide is usually used as an electrode, but the application and promotion of electric vehicles and smart grids are difficult because of the high price of bismuth.

The research team at Tokyo Denki University in Japan used titanium metal to develop high-performance batteries, which are only one-tenth the price of metal crucibles. The team found that the cheaper titanium-manganese materials have an energy density of more than 1000 milliwatt-hours per gram, which is twice the amount of material used in current lithium-ion batteries for electric vehicles. Nagoya Institute of Technology and Ritsumeikan University also participated in joint research.

This achievement opens up a new path for further searching for other electrode materials with higher storage capacity, and also opens up the possibility of developing large-capacity lithium batteries, and is expected to promote the extended travel distance of electric vehicles. The research report was published in the British science journal NATURECOMMUNICATION.
