Abstract
The invention provides a lithium slurry battery system with independent charging and discharging, comprising: a positive electrode cavity, in which positive electrode slurry is accommodated; a charging negative electrode cavity, in which a first negative electrode active material layer is arranged; a first isolation layer, which is located between the charging negative electrode cavity and the positive electrode cavity; the discharging negative electrode cavity, in which the second negative electrode active material layer is arranged; the second isolation layer, which is located between the discharging negative electrode cavity and the positive electrode cavity. Wherein, during the charging process of the battery, the lithium ions in the positive electrode slurry in the positive electrode cavity are deintercalated and embedded into the first negative electrode active material layer in the charging negative electrode cavity; The lithium ions in the negative electrode active material layer are deintercalated and intercalated into the positive electrode slurry in the positive electrode cavity. The operation and operation of the lithium slurry battery system with independent charge and discharge is more flexible, and is not restricted by time and place, and can solve the safety problem of lithium dendrites puncturing the isolation layer produced by traditional lithium slurry batteries.
Description
technical field [0001] The invention relates to the field of energy storage batteries, in particular to a lithium slurry battery system with independent charging and discharging. Background technique [0002] New energy technologies such as solar energy and wind energy are characterized by instability, discontinuity, and uncontrollability, and energy storage technology is an effective measure to solve the above problems. Electrochemical energy storage technology uses chemical elements as the energy storage medium, which is accompanied by the chemical reaction process of the energy storage medium during the charging and discharging process. Lithium slurry battery is a new type of lithium battery. The reactor of the lithium slurry battery is equipped with a conductive paste, which contains a certain proportion of conductive particles suspended or precipitated in the electrolyte. Therefore, it can move locally in the electrolyte to form a dynamic conductive network. The cond...
