An anion-immobilized composite electrolyte for dendrite-free lithium metal anodes
Tsinghua University · Beijing Institute of Technology
Abstract
Significance The Li metal electrode is regarded as a “Holy Grail” anode for next-generation batteries due to its extremely high theoretical capacity and lowest reduction potential. Unfortunately, uncontrolled dendrite growth leads to serious safety issues. This work realizes a dendrite-free Li metal anode by introducing an anion-immobilized composite solid electrolyte, where anions are tethered to polymer chains and ceramic particles. Immobilized anions contribute to uniform distribution of Li ions and dendrite-free Li deposition. The flexible electrolyte can be applied in all–solid-state Li metal batteries with excellent specific capacities. This work demonstrates a concept to adjust ion distribution based on…
