Abstract

The invention discloses a storage battery module for quickly responding humidity change. A humidity-sensitive sensor module is mounted outside the storage battery module, so that the humidity-sensitive sensor module can detect the change of humidity in the ambient environment of the humidity-sensitive sensor module in the using process of a storage battery, and the storage battery can be well protected; the humidity-sensitive sensor module is creatively designed in the aspects such as the sensitive material, manufacturing condition and structure of the sensor, so that the storage battery module is high in response speed, high in sensitivity and good in test repeatability, an unexpected technical effect is generated, and the storage battery module has great market application prospects.

Description

technical field [0001] The invention belongs to the field of storage batteries, and more particularly relates to a storage battery module for rapidly responding to humidity changes. Background technique [0002] A battery is a chemical device that stores chemical energy and releases its electrical energy when necessary. Generally, chemical reactions occur during its work. The battery can directly convert chemical energy into electrical energy, and its chemical reaction is reversible during charging and discharging. [0003] During the operation of the battery, the surrounding environment sometimes has high humidity, which may lead to corrosion and failure of the battery module. However, the existing battery generally does not have the ability to detect its environmental humidity. SUMMARY OF THE INVENTION [0004] In view of the problems existing in the background art, the present invention provides a battery module for rapidly responding to changes in humidity. [0005] ...
