Title: METAL ION/CHELATING RESIN-LITHIUM METAL COMPOSITE OXIDE BATTERY AND NEGATIVE ELECTRODE THEREOF
Abstract:
The present invention discloses a negative electrode of a metal ion/chelating resin battery. The electrode comprises: a negative electrode current collector and a negative electrode material layer distributed on the negative electrode current collector. The negative electrode material layer comprises: a frame, a chelating/adsorbing functional group fixedly disposed on the frame, and a metal ion attached, by means of an ionic bond or coordinate bond, to the chelating/adsorbing functional group. An elemental metal material for replenishing an active metal ion is provided in at least one of the following locations: between the negative electrode current collector and the negative electrode material layer; within the negative electrode material layer; or on a side of the negative electrode material layer away from the negative electrode current collector. The invention further discloses a manufacturing method for a negative electrode of a metal ion/chelating resin battery, and for a metal ion/chelating resin-lithium metal composite oxide battery.
