What should I do to store lithium batteries safely?

Regarding the primary battery, the battery life is important to refer to the shelf life of the battery, that is, the time required for the battery to reach the specified performance indicators after being placed under no load. Self-discharge is an important factor affecting battery life. In addition, battery life is also related to usage conditions, such as temperature and operating current. Regarding the secondary battery, in addition to the shelf life, the life of the charge-discharge cycle is more important. The Coulomb efficiency of the battery largely determines the cycle life of the secondary battery. There are many factors that reduce cycle life. Regarding the electrode, repeated charge and discharge reduce the active surface area of u200bu200bthe electrode, increase the current density, and increase the polarization. The structure of the active material changes; the electrical contact of the active particles becomes worse and even falls off. Corrosion of electrode materials, including fluid collection. In the electrolyte solution, the electrolyte or conductive salt decomposes to reduce the conductivity, resulting in passivation of the interface. In addition, clogged or damaged membranes, and short circuits inside the battery will shorten battery life. Battery safety performance: In order to ensure that the battery is safe and reliable during use, the battery and power supply with stricter performance requirements, especially before the actual application, the battery must pass a comprehensive safety test. The specific test content includes: In charge and discharge capacity test, short circuit test, high temperature resistance test and drilling test, corrosion resistance test, etc. For specific test methods and inspection standards, see the section on battery safety performance tests. The mechanical properties of the battery: mechanical properties include collision resistance, impact resistance and impact resistance.
