Polymeric microsphere-coated anode

Abstract

A lithium-ion battery cell includes a positive electrode including a positive electrode active material, a negative electrode including a negative electrode active material, a polymer-containing layer interposed between the positive electrode and the negative electrode, and an electrolyte contacting the positive electrode and the negative electrode. The polymer-containing layer includes a polymeric composition having a melting point from about 80° C. to about 170° C. The electrolyte includes lithium ions that are transported between the negative electrode and the positive electrode, Advantageously, lithium ion transport is stopped upon melting of the polymeric composition. A method for forming the lithium-ion battery cell is also provided.
