NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY, LITHIUM ION SECONDARY BATTERY COMPRISING SAME, AND METHOD FOR PRODUCING NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERY |
摘要 |
The present invention addresses the problem of providing: a negative electrode that is for a lithium ion secondary battery, that has high initial charge/discharge efficiency, and that has high energy density; a lithium ion secondary battery comprising the negative electrode for a lithium ion secondary battery; and a method for producing the negative electrode for a lithium ion battery that makes it possible to efficiently pre-dope an alkali earth metal or an alkali metal such as lithium. In order to solve this problem, this negative electrode for a lithium ion secondary battery comprises a negative electrode mixture layer containing at least: an alloy material (A) comprising tin or silicon capable of occluding lithium; carbon particles (B); an imide bond-containing polymer (C); and a polycyclic aromatic compound (D). The amount of the imide bond-containing polymer (C) within the negative electrode mixture layer is 3-13 mass%. |
