【SMM popularization of science.: Applications of Electrolyte Additives in Lithium Battery Industry】Electrolyte additives refer to a small amount of additives added to the electrolyte to improve its electrochemical properties and cathode deposition quality. By adding a small amount of additives to the electrolyte of lithium-ion batteries, some properties of the batteries can be improved in a targeted way, such as reversible capacity, electrode/electrolyte compatibility, cycle performance, rate capability and safety, etc. They play a very critical role in lithium-ion batteries. The amount of electrolyte additives is usually very small, but they are indispensable parts of the electrolyte system.

"Manipulating the Solvation Structure and Interface via a Bio-Based Gre" by Yan Wang, Xiaohui Zeng et al.

The practical application of aqueous zinc-ion batteries (AZIBs) is limited by serious side reactions, such as the hydrogen evolution reaction and Zn dendrite growth. Here, the study proposes a novel adoption of a biodegradable electrolyte additive, γ-Valerolactone (GVL), with only 1 vol.% addition (GVL-to-H2O volume ratio) to enable a stable Zn metal anode. The combination of experimental characterizations and theoretical calculations verifies that the green GVL additive can competitively engage the solvated structure of Zn2+ via replacing a H2O molecule from [Zn(H2O)6]2+, which can efficiently reduce the reactivity of water and inhibit the subsequent side reactions. Additionally, GVL molecules are preferentially adsorbed on the surface of Zn to regulate the uniform Zn deposition and suppress the Zn dendrite growth. Consequently, the Zn anode exhibits boosted stability with ultralong cycle lifespan (over 3500 h) and high reversibility with 99.69% Coulombic efficiency. The Zn||MnO2 ful
