The phrase "battery cathode" refers to the part of a battery where chemical reactions occur during its operation. It is the negatively charged electrode that allows the flow of electric current out of the battery. Full definition
In a further statement to the FT, Bitran asserted that Tesla could, in the future, even manufacture battery cathodes in the South American nation, since Chile has some of the world's most affordable solar power. (teslarati.com)
A multi-institution team of scientists led by Texas A&M University chemist Sarbajit Banerjee has discovered an exceptional metal - oxide magnesium battery cathode material, moving researchers one step closer to delivering batteries that promise higher density of energy storage on top of transformative advances in safety, cost and performance in comparison to their ubiquitous lithium - ion (Li - ion) counterparts.
