Abstract: Cathodes for a fast charging lithium ion battery, processes for manufacturing thereof and corresponding batteries are provided. Cathode formulations comprise spinel and/or layered structure cathode material with 5-10% of cathode material having an olivine-based structure as polymerization initiator, binder material, and monomer and/or oligomer material selected to polymerize into a conductive polymer upon partial delithiation of the olivine-based structure cathode material during at least a first charging cycle of a cell having a cathode made of the cathode formulation. When the cathode is used in a battery, polymerization is induced in-situ (in-cell) during first charging cycle(s) of the battery to provide a polymer matrix which is evenly dispersed throughout the cathode.
