The increasing demand of power sources for many portable electronic devices has efforts to develop lithium secondary batteries with high energy density. It makes their operating condition get severe and severe. However it is difficult to fulfill all the requirements of electrolyte with limited organic solvents and lithium salts. So we need to use some special additives for electrolytes to enhance the electrochemical performance of the cells. Among various additives, SEI layer stabilizer, which can significantly influence on the interfacial resistance of anode, is very important for good cyclability of the cell. Although VC (vinylene carbonate) has been known as a typically good SEI layer stabilizer. But it has high cost. In order to solve the above problems, we designed new electrolyte system with additives based on silane compounds and anion recepting material. |
