Abstract

The invention discloses a battery and a battery system. The battery comprises a packaging body, and a battery cell and an electrolyte which are packaged in the packaging body, wherein the battery cell comprises a positive plate, a diaphragm and a negative plate. The battery also comprises a heat exchange member, wherein the heat exchange member comprises an inner exchange part which is arranged in the packaging body and is in heat exchange cooperation with the battery cell, and an outer exchange part which is in heat exchange connection with the inner exchange part and extends out of the packaging body. The heat exchange member is arranged to exchange heat with the outside of the battery, so that the battery cell is cooled, and fire and explosion caused by overheating of the battery cell are avoided; and meanwhile, the heat exchange member can also be used for heating the battery cell when the battery works in a low-temperature environment, so that the service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a battery and a battery system. Background technique [0002] In the context of the global development of new energy vehicles, the power lithium battery market has maintained a rapid growth trend in recent years. At present, commercialized power batteries have reported safety accidents such as fires and explosions in passenger cars. There is a common factor in the safety accidents of power batteries, that is, the temperature of lithium-ion batteries continues to heat up during use, and thermal runaway causes the batteries to catch fire and explode. Contents of the invention [0003] The present invention aims to provide a battery and a battery system, which can effectively solve the problem of battery overheating. The present invention is realized by the following technical solutions: [0004] The first aspect of the present invention provides a battery, inclu...
