Application of boron compounds to electrolyte of Li-ion battery

The application of some boron compounds to Liion batteries as solvents,solutes and additives in electrolyte was introducedThe electrolytes which contained B2O3 or compound with a (BO)3 ring could reduce the loss of capacity during cycling and improve the cycliability of Li ion batteries,but also increased the irreversible capacity loss during the first cycleIn polymer electrolytes,the addition of compounds containing (BO)3 ring could improve Li+ transference number and reduce resistance between electrode and electrolyteBorates which had low melt point and high boiling point could improve battery performance under low and high temperaturesAs solutes,lithium organoborates with a big anion could improve the electrochemical window and conductivity of electrolyte
