Abstract

Belonging to the technical field of batteries, the invention specifically relates to a semisolid flow lithium ion battery. The battery is composed of two tanks, a generation chamber, a diaphragm, electron guiding devices, drainage pumps and ducts. Specifically, a positive fluid and a negative fluid are respectively stored in the two tanks; the tanks are connected to the generation chamber through the ducts and the drainage pumps; the generation chamber is divided into a positive area and a negative area, positive pole and negative pole plates are respectively guided out of the generation chamber through pole columns to form electron guiding devices. During energy storage, slow self-discharging between the positive electrode and the negative electrode can be avoided; while during energy release, the positive electrode and the negative electrode are respectively introduced into the generation chamber for discharging, so that energy storage and release are separated. By replacing positive and negative fluids for charging, the battery charging problem is solved. The semisolid flow lithium ion battery of the invention has improved battery energy density and reduced cost, and well solves the self-discharging and rapid charging problems of lithium ion batteries, thus boasting wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a semi-solid flow lithium-ion battery. Background technique [0002] A normal lithium-ion battery is composed of a positive electrode, a negative electrode, a separator, an electrolyte, an electron extraction device, and a battery case. The positive electrode, negative electrode, separator, and electrolyte are all placed in the battery case. When the battery is charged, lithium ions are inserted into the negative electrode material from the positive electrode through the electrolyte; when the battery is discharged, lithium ions are inserted into the positive electrode material from the negative electrode through the electrolyte. The battery completes the storage and release of energy through the above-mentioned redox process. In this way, all the reactive substances of the battery are placed in a battery case, and the battery will produce self-discharge when it is...
