Estimating the term…
A lithium secondary battery comprises a cathode 1 capable of charging and discharging lithium ions, an anode 2 formed from a material which can be doped and de-doped with lithium ions, lithium metal, or the like, and an electrolyte that allows the movement of lithium ions. The anode 2 contains an imide compound represented by the chemical formula below. In the chemical formula above, Z is an optionally substituted —(CH2)n— (where n is an integer from 2 to 7), 1,2-cyclohexylene or 1,2-phenylene; X is a hydrogen atom, or an optionally substituted alkyl group, aralkylcarbonyl group, alkylcarbonyl group, alkoxycarbonyl group, aralkyloxycarbonyl group, or imidyloxycarbonyl group.
A lithium secondary battery comprising:
An anode for a lithium secondary battery, comprising an anode active substance and an imide compound which is presented by the chemical formula below:
A method for manufacturing an anode for a lithium secondary battery, the anode comprising an anode active substance and an imide compound, the method comprising the steps of:
A method for manufacturing an anode for a lithium secondary battery, the anode comprising an anode active substance and an imide compound, wherein said anode active substance is heated and melted together with said imide compound for dispersing said imide compound in said anode active substance;
A method for manufacturing an anode for a lithium secondary battery, the anode comprising an anode active substance and an imide compound, wherein said imide compound is applied onto the surface of an ingot containing said anode active substance when said ingot is extrusion molded;
