Currently, the most commonly used battery separators are polymeric separators, mainly made of polypropylene (PP) or polyethylene (PE).

This copper foil is an indispensable component of modern lithium-ion batteries. It serves as the substrate and current conduction pathway for the battery's negative electrode (typically graphite or other active materials).

battery separator ​play a silent yet critical role: they physically isolate the anode and cathode while enabling ion transport, a balance that directly impacts safety

A sodium-ion battery is mainly composed of a positive electrode, a negative electrode, an electrolyte, a separator, and a current collector.

Manual Coin Cell Electrode Disc Cutter is a precise tool specially designed for the preparation of coin battery electrode.
