Abstract

The invention provides an anode material for liquid-state and semi-liquid-state metal energy-storing batteries, belongs to an electrode material of an energy-storing battery, and solves the problems that the operation temperature is high, the working voltage is low, the corrosion is strong and the pollution to the environment is caused in an existing liquid-state metal battery. The anode material is Sn alloy formed by metal Sn or the Sn and one or more than one monomer of Sb, Pb, Bi and Te. The metal Sn or the Sn alloy is used as the anode material, the smelting point of the metal Sn is low (231.9 DEG C) and the metal Sn has no environmental pollution; the Sn alloy is simple to prepare and is low in cost; the metal Sn, the Sn alloy and an existing cathode material have the good alloy performance and have stability under a high temperature; when the metal Sn and the Sn alloy are applied to a liquid-state metal battery and a semi-liquid-state double-metal battery, the operation temperature can be lowered, the maintenance cost can be reduced, the voltage of the battery can be increased or stabilized, the large-current and high-density charging/discharging performance of the battery is improved, and the service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to electrode materials for energy storage batteries, in particular to a class of positive electrode materials for liquid and semi-liquid metal batteries. Background technique [0002] The development and utilization of renewable energy such as wind energy and solar energy has always been the focus of attention in the energy field. However, there are still great challenges in the effective grid connection of wind energy and solar power generation. Large-scale energy storage is one of the key technologies to meet this challenge. one. Therefore, in recent years, the research and development of high-efficiency and cheap large-scale energy storage battery systems has become a hot spot in the field of electrochemical energy storage, such as modified lead-acid batteries, lithium-ion batteries, sodium-sulfur batteries, etc. However, many energy storage parameters of current electrochemical energy storage technology, especially price and ...
