Why are lithium dendrites a problem in a battery separator?

5. Mechanically Strengthened Separator Fabrication When lithium dendrites nucleate and grow inside the battery, due to the low elastic modulus of the traditional separator, lithium dendrites easily pass through the separator and cause an internal short circuit in the battery [103, 104].

Are cellulose separators good for lithium batteries?

Why does a lithium dendrite separator have a short circuit?

This is mainly due to the pore structure of the separator, determined by the porosity, pore size and pore curvature, which dictates the effectiveness of the separator in inhibiting dendrite diffusion [117, 118]. Excessive or insufficient porosity and pore size in the separator can result in short circuits caused by lithium dendrites .
