Tesla patents a new NCA electrode that is likely going to be used in its new battery cell built in-house, which is expected to be longer-lasting and cheaper. We previously reported on Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University, unveiling the impressive results of tests on e new battery cell […]

Researchers led by Prof. Jian Liu and Prof.Zhongshuai Wu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have developed Fe1-xS-decorated mesoporous carbon spheres as a cathode material for lithium-sulfur batteries. Fe1−xS‐NC has a high specific surface area (627 m2 g−1), large pore volume (0.41 cm3 g−1), and enhanced adsorption and electrocatalytic transition […]
