Analysis of Electrode-Electrolyte Interactions in Commercial Layered Oxide/Hard Carbon Sodium-Ion Batteries Using Optical Sensors

Main Findings The composition of the cathode material significantly affects the initial charging behavior of commercial layered oxide/hard carbon sodium-ion batteries. Compared to the P2 cathode, the O3 cathode induces more severe electrolyte decomposition, accompanied by significant heat generation and gas evolution at high state of charge. Although the additives succinonitrile (SN) and propylene-1,3-sultone (PES) … Read more

Latest Review by Wuhan University Team in Chem Soc Rev: Recent Research and Prospects of Non-flammable Electrolytes for Sodium-ion Batteries

Recently, the Wuhan University team summarized the development of non-flammable electrolytes for sodium-ion batteries, covering both liquid (e.g., adding 5wt% PFPN to organic electrolytes to suppress flammability) and solid (e.g., NASICON with a room temperature conductivity of 6.0 mS/cm) systems. The team elucidated the flame-retardant mechanisms and proposed five optimization directions, with some systems (e.g., … Read more
