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.

Positive electrode composition, a positive electrode of a lithiumion electrochemical cell, and a method of forming the positive electrode

A lithium ion battery component includes a support selected from the group consisting of a current collector, a negative electrode, and a porous polymer separator. A lithium donor is present i) as an additive with a non-lithium active material in a negative electrode on the current collector, or ii) as a coating on at least a portion of the negative electrode, or iii) as a coating on at least a portion of the porous polymer separator. The lithium donor has a formula selected from the group consisting of LiMP, wherein M is Fe, V, or Mn and wherein y ranges from 1 to 4; LiTiP, wherein y ranges from 1 to 2; LiP, wherein 0&#x3c;x&#x2264;3; and LiCuP.
