Abstract
Disclosed is a method for preparing the anti-sintering calcium-based energy storage material by vacuum freeze-drying, which includes preparation of a precursor solution by mixing a calcium salt and a metal salt of manganese, magnesium, iron, cobalt, aluminum, zirconium, titanium, chromium, nickel, lanthanum, yttrium, molybdenum, or other metals in deionized water, vacuum freeze-drying of the precursor solution to obtain fluffy powder, and calcination of the powder in an air atmosphere to obtain the anti-sintering calcium-based energy storage material. The preparation method of the present invention does not require special equipment and harsh conditions, and has strong operability. The prepared calcium-based energy storage materials feature strong stability, high energy storage capacity, etc., and can be used in industrial production.
