Abstract

The invention provides a zinc paste, a preparation method thereof and a zinc-manganese battery. The zinc paste comprises a zinc-containing material, an indium-containing material, a binder and a thickener, and the binder is a pre-gelatinized material. The preparation method comprises the following steps: stirring and mixing the zinc-containing material, the indium-containing material, the binder and the thickener according to a formula ratio, adding an electrolyte, and continuously stirring and mixing to obtain the zinc paste, and the binder is the pre-gelatinized material. The zinc paste provided by the invention can be used for a weakly acidic electrolyte, the charging and discharging capacity of the battery can be guaranteed, the capacity retention ratio of the zinc-manganese battery isimproved, and the cost is low.

Description

technical field

[0001] The invention belongs to the technical field of batteries, and relates to a zinc paste, a preparation method thereof and a zinc-manganese battery. Background technique

[0002] In recent years, lithium-ion batteries (LIBs) have been extensively studied in the field of electrochemistry due to their high energy density, long cycle life, small self-discharge, and no memory effect, and they occupy a large market share. However, lithium-ion batteries are costly, limited in lithium resources, and less safe. Therefore, it is particularly important to develop secondary batteries with high capacity, fast charging and discharging, good safety, rich raw material resources, environmental friendliness and strong adaptability. Based on the above problems, the replacement of organic electrolytes with water-based electrolytes is expected to reduce costs, increase power density, and improve safety performance. The aqueous solution system of multivalent zinc-ion batter...
