As the vital roles such as electrodes, interlayers, separators, and electrolytes in the battery systems, regulating the membrane porous structures and selecting appropriate membrane materials are significant for realizing high energy density, excellent rate capability, and long cycling stability of lithium rechargeable batteries (LRBs).
Membrane electrode assembly (MEA) with PEO-based electrolyte and LiFePO 4 electrode operates in polymer lithium cell at 70 °C. The cell delivers 155 mAh g −1 at 3.4 V for over 100 cycles without signs of decay. The all-in-one approach is suited for scaling up polymer lithium cells with high cathode loading to the pouch cell configuration.
Overall, persistent challenges pertaining to the unsatisfactory thermal stability of lithium battery separator membranes, insufficient shutdown functionality, and suboptimal ion conductivity present pressing areas of inquiry that necessitate meticulous analysis and dedicated investigation.
More importantly, the asymmetric porous structured membrane with a dense layer can act as an active material and current collector, avoiding the use of separate current collectors, even conductive agents and binders in lithium-ion battery, which is beneficial for superior electrochemical performances in terms of high reversible capacity.
Moreover, the membranes can serve as separators in conventional battery systems, as well as electrodes and electrolytes in advancing research. Regulating the membrane structure and selecting appropriate membrane materials are significant for realizing a high energy density, excellent rate capability, and safety of LRBs.
