A salt-free medium facilitating electrode prelithiation towards fast-charging and high-energy lithium-ion batteries.

ABSTRACT: The substantial consumption of lithium ions and sluggish reaction kinetics at the anode detrimentally impact the deliverable energy and fast-charging capability of lithium-ion batteries with silicon-based anodes. The prevailing contact prelithiation method using an electrolyte medium can replenish the active lithium, but it may cause materials/electrode instability and bring barrier for lithium-ion transport. Here we explore a contact prelithiation methodology employing cyclic carbonate mediums that can enable spatially and temporally uniform prelithiation reaction. These mediums enable a delicate equilibrium between a lithium-ion diffusion and the intrinsic prelithiation reaction rate throughout the electrode depth. Not only does this prelithiation method serve the fundamental purpose of
