Heat storage and cold storage battery for thermoelectric refrigeration

Abstract

The invention relates to the field of batteries, in particular to a heat storage and cold storage battery for thermoelectric refrigeration. The heat storage and cold storage battery for thermoelectricrefrigeration comprises a thermoelectric refrigerator, a first circulating pipeline and a second circulating pipeline, wherein the first circulating pipeline is connected with a cold surface of the thermoelectric refrigerator; the second circulating pipeline is connected with a hot surface of the thermoelectric refrigerator; energy storage media are separately arranged in the first circulating pipeline and the second circulating pipeline; a first medium pump which is used for driving the energy storage medium in the first circulating pipeline to circularly flow along the first circulating pipeline is arranged on the first circulating pipeline; and a second medium pump which is used for driving the energy storage medium in the second circulating pipeline to circularly flow along the secondcirculating pipeline is arranged on the second circulating pipeline. The heat storage and cold storage battery for thermoelectric refrigeration is simple in structure and easy to implement and popularize; abundant electric energy can be stored and delivered to a power grid when in peak demand for electricity, and therefore, idling of power generation equipment and waste of resources are avoided.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a thermoelectric refrigeration, heat storage and cold storage battery. Background technique [0002] The conversion and storage of electric energy are currently mainly focused on four research directions: lithium-ion batteries, hydrogen fuel cells, supercapacitors and aluminum-air batteries, among which lithium-ion batteries have been widely used. [0003] Although the lithium-ion battery is considered as a green battery with little environmental pollution, its structure is complex and its manufacturing cost is high. Moreover, the positive and negative electrode materials and electrolytes that make up the lithium-ion battery contain metals such as nickel and manganese. A battery with the most toxic substances in the battery. Moreover, the recycling process is complicated, the recycling rate is not high, and discarded batteries have a greater impact on the environment. Therefore, the sub...

Problems solved by technology

[0003] Although lithium-ion batteries are considered to be green batteries with little environmental pollution, they have complex structures and high manufacturing costs. Moreover, the positive and negative electrode materials and electrolytes that constitute lithium-ion batteries contain metals such as nickel and manganese. A battery with the most toxic substances in the battery

Moreover, the recycling process is complicated, the recycling rate is not high, and the discarded batteries have a greater impact on the environment. Therefore, the subsequent hidden costs of lithium-ion batteries are relatively high.

In addition, due to the limitation of the characteristics of electrochemical materials, the number of cycles of lithium-ion batteries has not broken through, and the service life is short
