Electrolyte engineering is emerging as a key strategy for enhancing the cycle life of lithium metal batteries (LMBs). Fluorinated electrolytes have dramatically extended cycle life; however, intractable challenges regarding the rate capability and fluorine overuse persist. Here, we introduce a lithiophilic, solvent-interactive, and fluorine-free nano-Si3N4 additive that facilitates the fine-tuning

The deployment of lithium-ion batteries, essential for military and space exploration applications, faces restrictions due to safety issues and performance degradation stemming from the uncontrollable side reactions between electrolytes and electrodes, particularly at high temperatures. Current research focuses on interfacial modification and non-flammable electrolyte development, which fails to simultaneously

Eutectic electrolytes (EEs) have garnered significant attention in the field of metal-ion batteries due to their remarkable properties, including high flame retardancy and excellent thermal and electrochemical stability. Beyond the intrinsic advantages of EEs, the potential of composite electrolytes formed by combining EEs with other electrolytes is emerging as a crucial area of research and development

The non-homogeneity of nickel oxide (NiOx) nanoparticles (NPs) and the problematic interlayer interconnectivity with perovskite film are the current major bottlenecks for the further development of corresponding perovskite solar cells (PVSCs). Herein, a multistage growth template strategy is proposed to successively ameliorate the crystallization kinetics of NiOx NPs and perovskite film by modulating

Aqueous Zn-I2 batteries are promising candidates for grid-scale energy storage due to their low cost, high voltage output and high safety. However, Ah-level Zn-I2 batteries have been rarely realized due to formidable issues including polyiodide shuttling and zinc dendrites. Here, we develop 10 Ah dual-plating Zn-I₂ batteries (DPZIB) by employing ZnIxG4(tetraglyme) complex chemistry, in which zinc and

Recently, we have proposed micelle-like structures to fully understand microstructures in localized high-concentration electrolytes (LHCE) that show many benefits to high-capacity electrodes. It is critical to understand the electrical double layer (EDL) structures of LHCE, how they differ from the bulk electrolyte structure, and how they impact the solid electrolyte interphase (SEI) formation on Li-metal
