ABSTRACT:
Heat and pressure can be used to re-flow active material at the edges of an electrode section to coat burrs at the edges of the electrode section. These burrs are typically formed in the cutting of the current collector and active material to form the electrode sections. By coating the burrs with the active material, shorts are prevented when the electrode sections are laminated with the other battery sections to form a battery stack.
