Title:
HIGH-EFFICIENT IONIC CONDUCTION TYPE LITHIUM ION BATTERY OR LITHIUM ION CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2017/126701
Kind Code:
A1
Abstract:
The present invention improves the initial-capacity retention rate, the rate characteristics, and the capacity utilization rate per cycle in a lithium ion battery or lithium ion capacitor. The present invention is achieved by providing a lithium ion battery or lithium ion capacitor having a lamination structure of a positive electrode/an electrolytic layer including a separator/a negative electrode, wherein: the positive electrode and/or the negative electrode is obtained by using, as a binder for binding the active material of the positive electrode and/or the negative electrode to a conductive material, a conductive raw material that contains, in a fluorine-based polymer (X2), 0.1-95 wt% of a polymer conductive composition (X1) obtained by graft polymerization or living polymerization of a molten salt monomer by 2-90 mol% in a fluorine-based polymer, the molten salt monomer having a polymerizable functional group and a salt structure that includes an onium cation and a fluorine-containing anion; and the electrolytic layer is formed of the separator, and (1) a salt (X3) including a fluorine-containing anion and at least one cation selected from among an aromatic cation, a cyclic aliphatic cation, and an non-cyclic aliphatic cation, (2) the polymer conductive composition (X1), or (3) the polymer conductive composition (X1) and (X3).
