Report: Sumitomo and Kyoto University developing lower temperature molten-salt battery; about 10% the cost of Li-ion

Green Car Congress

in partnership with Kyoto University, has developed a lower temperature molten-salt rechargeable battery that promises to cost only about 10% as much as lithium ion batteries. Molten-salt batteries use highly conductive molten salts as an electrolyte, and can offer high energy and power densities.

AIST researchers synthesize new class of high-voltage, high-capacity cathode materials for Li-ion batteries

Green Car Congress

Since the commercialization of Li-ion batteries by Sony in 1991, lithium cobalt oxide (LiCoO 2 ) has been extensively studied as a positive electrode material in rechargeable lithium batteries. A paper on their work is published in the Journal of Power Sources. Recently, a lithium-deficient nickel manganese oxide Li 0.7 However, O3-Li 0.7

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. They gradually lose capacity with each discharge and recharge cycle, and they can be fire hazards.
