Ball Milling Battery

Ball Milling Battery

Ballmilling for a sufficient period of time of lithium−manganese oxide spinels prepared either by a sol−gel method or by solidstate reaction gave cathode materials of a lithium cell with excellent capacity retention in the 3v range at room temperature and elevated temperatures despite an apparent jahn−teller distortion in a 50cycle test
