A thin and flexible solid electrolyte templated by controllable porous nanocomposites toward extremely high performance all-solid-state lithium-ion batteries

Research progress in stable interfacial constructions between composite polymer electrolytes and electrodes

“…Ni et al developed a high quality CPE by using lignin nanoparticles (LNPs) to regulate the pore characteristics of a cellulose nanofibril (CNF) film template. 140 The synthesis process is shown in Fig. 8c.…”

A sustainable delamination method to completely separate spent cathode foils via biomass-derived γ-valerolactone

“…33,34 Recently, GVL has been extensively investigated for material synthesis, manufacture, and recycling. 35–37 Ravikumar et al revealed that GVL could dissolve PVDF and be handled like NMP if processed at a temperature of 60 °C. 38 GVL is indeed more expensive than many conventional dipolar aprotic solvents (seen in Table S1†), which is related to the temporary lack of large-scale application of GVL.…”

Design of a hydrolysis‐supported coating layer on the surface of Ni‐rich cathodes in secondary batteries

“…(2) The carbonate component of the residual Li is easily attacked by HF generated by a negligible number of water molecules present in the electrolyte and decompose to generate gas, which causes the battery to explode 18‐21 . In addition, the low thermal stability of the material causes the let off O from the crystal lattice in a highly deintercalated state, which oxidizes the electrolyte to easily generate HF or LiF, thereby accelerating gas generation or rapidly decreasing the electrochemical performance 20,22‐24 . Hence, in the case of high‐Ni LNCM, the structural and electrochemical performance decreases at high temperature and high voltage within a shorter duration than in the conventional layered structure, and the amount of gas generated inside the battery is high, making it very vulnerable to instability.…”
