Impact of tripropyl borate on life and impedance of lithium-ion cells.
Tripropyl borate was investigated as a low cost anion receptor to improve the performance of lithium-ion cells. The impact of tripropyl borate was examined using lithium-ion cells comprising a negative electrode of mesocarbon microbeads, a positive electrode of Li{sub 1.1}[Mn{sub 1/3}Ni{sub 1/3}Co{sub 1/3}]{sub 0.9}O{sub 2} and an LiPF{sub 6}-based electrolyte. It was found that the performance of the cells was improved by adding a proper amount of tripropyl borate ({le} 0.1 wt%) to the LiPF{sub 6}-based electrolyte. However, a small amount of gas was observed from cells with high contents of tripropyl borate when cycled at 55 C, and as a result, the performance of the cells deteriorated.
