Silicon borane anions

SEI through reductive decomposition of the bis (oxalate) borate anion [103, 104]. Monofluoroethylene carbonate (FEC) can improve the cycling performance of Si-based anode material due to the generation of a more fluorinated SEI layer and inhibition of LiF production [104, 105]. Tris (pentafluorophenyl) borane (TPFPB) also was reported as an electrolyte additive for silicon thin-fihn electrode due to the formation of stable SEI, which therefore suppresses the surface pulverization [106]. The same research group also disclosed another additive, succinic anhydride (SA), as an electrolyte additive for sihcon thin-fihn electrode. Similar mechanism was proposed by the authors that addition S A can prevent the decomposition of LiPFg salt the Si surface and an SEI layer with higher hydrocarbon and LijCOs contents is formed on the Si surface [107].
