Advanced in modification of electrospun non-electrode materials for lithium-sulfur battery

The "shuttle effect" of polysulfides induces issues such as loss of active sulfur, corrosion and passivation of lithium anode, resulting in a decrease in the Coulombic efficiency and specific capacity during the process of charge-discharge of lithium-sulfur batteries (LSBs). Beside the sulfur carrier in cathode, the interlayer, separator, and solid/gel electrolyte as non-electrode materials for LSBs undertake the mainly role to restrain the "shuttle effect". In here, the research progress on the modification of functional membrane, interlayer and gel polymer electrolyte matrix by electrospinning for LSBs are reviewed. The general method and rules of interfacial modification and internal modification of non-electrode materials are summarized, and the application prospects of electrospinning in the preparation of non-electrode materials for LSBs are prospected.
