Abstract

The embodiment of the invention discloses a battery and a battery production method, wherein the battery comprises an isolation device, a cathode material, an anode material, a liquid conductor, a storage device and a shell; the resistance of the isolation device is larger than a preset threshold value; the cathode material and the anode material are arranged on the two sides of the isolation device respectively and are used for forming a cathode and an anode of the battery respectively; the liquid conductor is used for realizing transmission of conductive ions between the cathode and the anode; the storage device is used for storing a supplementary material, so that the supplementary material can be released through the storage device to increase the concentration of the conductive ions in the liquid conductor; and the shell is used for forming a closed or sealed cavity to accommodate the isolation device, the cathode material, the anode material, the liquid conductor and the storagedevice.

Description

technical field [0001] The present application relates to the battery field, and relates to but not limited to a battery and a battery production method. Background technique [0002] With the widespread application of lithium-ion batteries, how to prolong the service life of batteries is an important issue at present. [0003] At present, battery life is usually extended by adding too much electrolyte, or by supplementing additional conductive ions or electrolyte. However, adding too much electrolyte will lead to abnormal thickness of the battery and severe erosion of the battery pole piece, and additional supplementation of conductive ions or electrolyte will increase the complexity of the process and increase the difficulty of battery production. Contents of the invention [0004] The technical scheme of the embodiment of the application is realized in this way: [0005] In the first aspect, the embodiment of the present application provides a battery, including: [...
