High-performance Li-ion/metal batteries working at a low temperature (i.e., <-20 °C) are desired but hindered by the sluggish kinetics associated with Li+ transport and charge transfer. Herein, temperature-dependent behavior during Li plating is profiled various characterization techniques, suggesting that diffusion through solid electrolyte interface (SEI) layer key rate-determining step. Lowering not only slows down transport, also alters thermodynamic reaction of decomposition, resulting...
Enhancing the stability of interface between electrode and electrolyte at high voltages is crucial concerning development Li-ion batteries with energy densities. Application some additives in not only simplest but also most effective way to form a protection layer against decomposition corrosion electrode. Herein, we introduce trimethyl borate (TMB) as an additive commercial ameliorate performance LiCoO2 cell charged 4.5 V because its addition lowers oxidation potential baseline (3.75 vs...

Abstract Prelithiation is an essential technology to compensate for the initial lithium loss of lithium‐ion batteries due formation solid electrolyte interphase (SEI) and irreversible structure change. However, prelithiated materials/electrodes become more reactive with air resulting in unwanted side reactions contaminations, which makes it difficult practical application prelithiation technology. To address this problem, herein, engineering through a simple solution treatment after chemical...
