The primary objectives of our recent work are to markedly accelerate the practical applications of lithium-metal batteries and offer deep mechanistic understandings of this complicated system.
Li-metal batteries are the holy grail of the battery field and viewed as a promising next-generation battery technique, because they have ultra-high energy density, theoretically >500 Wh/kg.
Lithium-metal batteries introduced to date have a highly limited cycle life of approximately 50 cycles, significantly lower than that of commercial lithium-ion batteries, which usually retain good performance for approximately 1,000 cycles.
The new electrolyte design with a unique nanometer-scale solvation structure may enable the development of highly performing lithium-metal pouch cells with longer lifespans.
