Positive electrode composition, a positive electrode of a lithiumion electrochemical cell, and a method of forming the positive electrode
A positive electrode composition includes a binder material; an electrically conductive material dispersible in the binder material and comprising a plurality of conductive carbon particles; an active material dispersible in the binder material and comprising a plurality of active particles; and a coating agent comprising one of a non-lithiated polymer, an at least partially-lithiated polymer, and a fully-lithiated polymer. The coating agent is disposed on and at least partially encapsulates at least one of: each of the plurality of conductive carbon particles and each of the plurality of active particles. A positive electrode of a lithium ion electrochemical cell includes a current collector comprising aluminum and a layer formed from the positive electrode composition and disposed on the current collector. A method of forming the positive electrode is also disclosed.
