What is the best strategy for the mechanical reinforcement of soft SPEs in Lithium metal batteries?

Jannik published a Comparative Study of the Mechanical Reinforcement by Blending, Filling, and Block Copolymerization in Bottlebrush Polymer Electrolytes in ACS Appl. Polym. Mater. Both Filling and block copolymerization improves the reinforcement, but block copolymer approach has some additional advantages. https://doi.org/10.1021/acsapm.4c00161
