Tris(trimethylsilyl) borate as an electrolyte additive to improve the cyclability of LiMn2O4 cathode for lithium-ion battery

► TMSB used as additive to improve cyclability of LiMn2O4 cathode lithium-ion battery. ► The lithium-ion battery containing TMSB shows excellent capacity retention at 55 °C. ► TMSB participated in the formation of SEI on the surface of electrode. ► Enhancement of cyclability of Li anode by TMSB additive.
