Under the instruction of above-mentioned theoretical results, in the thesis chapter 10, the strongly electron-withdrawing anion, C_5O_5~(2-)[dianion of croconic acid (4,5-dihydroxycyclopent-4- ene-1,2,3-trione)], was chosen as the chelator to coordinate with boron to form lithium salt, which will yield high ionic conductivity solutions, and exhibit wide electrochemical stability windows and high thermal stability. As described in the chapter, two new lithium salts containing C_5O_5~(2-), lithium bisborate and its novel derivative, lithium borate for Li-ion battery electrolytes were synthesized.
