(57) [Summary]nThe present invention relates to a method for improving power density of a lithium secondary battery, particularly a battery containing a solution of a solid polymer, and an anode thereof. This is achieved by using boric acid esters and / or boric acid derivatives or compounds thereof as additives. In particular, a lithium compound of the corresponding complex is added. Further, the present invention includes an anode used for a battery, particularly a lithium ion secondary battery, and a battery having a solution of a solid polymer. It is contained in the anode. |
