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
