Methods for safety 795 Lithium Stage 1:the onset of overheating Separator Overcharging Cell crush dendrite flaws 1.Reliable anode materials a)Use compounds like vinylene carbonate and maleimide to stabilize the SEI and eliminate the dendrite growth 2.Multi-functional liquid electrolyte and separator a)Fumed SiO,in electrolyte-Sheer thickening effect-viscosity t upon pressure-dissipating the impact A Velocity Velocity Damaged Battery cell 象 EC/DMC EL/DMC EC/DMC with LiPF with LiPFs with LiPFe Velocity Velocity Battery cell Silica clusters Normal EC/DMC Silica particles with LiPFs 8Methods for safety Stage 1: the onset of overheating 1. Reliable anode materials a) Use compounds like vinylene carbonate and maleimide to stabilize the SEI and eliminate the dendrite growth 2. Multi-functional liquid electrolyte and separator a) Fumed SiO2 in electrolyte → Sheer thickening effect → viscosity ↑ upon pressure → dissipating the impact 8
