The pore size of the LPS-Separator significantly exceeds the requirement of lithium-ion battery separators (<1μm) [], making it susceptible to puncturing by dendrites during cycling. As depicted in Fig. 2 a, the overpotential of the Li-symmetric cell employing an LPS-Separator during galvanostatic cycling is negligibly small, close to …
Lithium metal is considered a promising anode material for lithium secondary batteries by virtue of its ultra-high theoretical specific capacity, low redox potential, and low density, while the application of lithium is still challenging due to its high activity. Lithium metal easily reacts with the electrolyte during the cycling process, …
