Lithium deposition in single-ion conducting polymer electrolytes

Lithium (Li)-metal is considered as promising anode material for high-energy-density rechargeable batteries, although its application hampered by inhomogeneous Li deposition and dendritic morphologies that could eventually result in contact losses of bulk deposited well cell short circuits. Based on theoretical investigations, recent works polymer electrolytes particularly focus the design single-ion conducting improvement Li+ transport properties, including enhanced transference numbers, ionic conductivity, mechanical stability, thereby affording safer potentially “dendrite-free” cycling Li-metal batteries. In present work, it revealed spatial microstructures, localized chemistry, corresponding distributions properties within electrolyte are also decisive achieving superior performances. Thus, targeted modification microstructures should be further critical parameters future development to actually control behavior longevity
