Currently, the primary material utilized for diaphragm construction is polyolefin film, primarily polypropylene (PP) or polyethylene (PE). Although the employment of thinner diaphragms has the potential to enhance the battery's mass ratio and bulk density, this reduction also carries an increased risk of compromising safety.
The overall reaction is the sum of these two half-reactions, representing the flow of lithium ions from the negative electrode to the positive electrode and the concurrent flow of electrons through the external circuit, thus releasing the stored energy from the battery.
