Abstract
(EN)
Provided, according to one embodiment, is an electrode comprising a current collector and an active substance-containing layer disposed on the current collector. The active substance-containing layer includes a first binder, first active substance particles, and second active substance particles. The first binder includes a first polymer material including a N-containing monomer containing a nitrogen atom. The first active substance particles include a lithium-containing manganese oxide, and have a first coverage by nitrogen atoms of 85-100%. The second active substance particles include a cobalt-containing compound, and have a second coverage by nitrogen atoms of 0-50%.
