A method of making a positive electrode includes forming a slurry of particles using an electrode formulation, a diluent, and oxalic acid, coating the slurry on a collector and drying the coating on the collector to form the positive electrode. The electrode formulation includes an electrode active material, a conductive carbon source, an organic polymeric binder, and a water soluble polymer. The diluent consists essentially of water.

Aqueous cathode slurry

Electrolyte solutions including additives or combinations of additives that provide low temperature performance and high temperature stability in lithium ion battery cells.

Electrolyte formulations for lithium ion batteries

In one embodiment, a positive electrode is formed by a process that includes forming a slurry including particles dispersed within a liquid from a electrode formulation and the liquid such that the particles have a particle size distribution Dof 15 microns or less, coating the slurry on a collector; and drying the coated collector to form the positive electrode. The electrode formulation includes an electrode active material, a conductive carbon source, an organic polymeric binder, and a water-soluble polymer. The liquid consists essentially of water or a mixture of water and an alcohol. When the liquid consists essentially of the mixture, the alcohol is present in an amount of less than 10% by weight, based on the weight of the slurry. When the liquid consists essentially of water, the slurry is formed from the electrode formulation, the liquid, and an arene-capped polyoxoethylene surfactant.
