Engineering the Solid Electrolyte Interphase for Enhancing High-Rate Cycling and Temperature Adaptability of Lithium-Ion Batteries In overcoming the barrier of rapid Li+ transfer in lithium-ion batteries under extreme temperatures, the desolvation process and interfacial charge transport play critical roles. However, tunning the solvation structure and designing kinetically-stable electrode-electrolyte interface to achieve high-rate charging and discharging remains challenges.

Nitrile Solvent Structure induced Stable Solid Electrolyte Interphase for Wide-Temperature Lithium-ion Batteries Lithium-ion batteries (LIBs) are extensively employed in various fields. Nonetheless, LIBs utilizing ethylene carbonate (EC)-based electrolytes incur capacity degradation in wide-temperature range, which is attributable to the slow Li+ transfer kinetics at low temperatures and solvent decomposition during high-rate cycling at high temperatures.

Green mechanochemical Li foil surface reconstruction toward long-life Li–metal pouch cells† The uncontrollable growth of Li dendrites and high cost hinder the commercial application of Li metal batteries (LMBs). Herein, a low-cost Li foil surface-reconstruction strategy based on a mechanochemistry reaction between fumed silica and Li is proposed to realize a dendrite-free Li metal anode for practical Li metal pouch cells.
