  The application fields of lithium-ion batteries for long-term storage, such as medical, military, and auxiliary power supplies, make it particularly important for batteries to have good long-term storage performance. The interior of lithium-ion batteries is a relatively complex electrochemical system. After being left unused for a long time, the equilibrium state inside gradually changes. When it accumulates to a certain extent, the battery often undergoes the following changes: cobalt acid lithium-ion batteries

  1. Physical characteristics

  According to the actual evidence of lithium-ion batteries stored for a certain period of time, the physical characteristics (appearance, size, weight, etc.) of the battery will undergo certain changes, especially the appearance characteristics. In situations where the temperature and humidity of the storage environment are poor, this trend is more pronounced.

  In cases of high humidity, the weight gain of lithium-ion batteries after long-term storage is significantly higher than that of batteries placed at low humidity. If the steel shell of the battery is prone to rust under high humidity conditions, resulting in a slight increase in mass. Rust will not have an impact on the internal state of the battery, but it will directly affect the shipment of the product and may have a negative impact on its supporting electronic components.

  2. Electrochemical characteristics

  Long term storage of lithium-ion batteries may result in some side reactions, such as electrolyte decomposition, dissolution of active substances, and lithium deposition. After a long period of shelving, the equilibrium state inside the lithium-ion battery gradually changes. When it accumulates to a certain extent, the battery will undergo significant changes, which will be directly reflected in the electrochemical characteristics of the battery.

  1) Capacity

  The changes in the capacity of lithium-ion batteries that have been shelved for a long time are mainly reflected in two aspects: firstly, the decrease in battery capacity, mainly caused by self discharge; The second is the increase in irreversible capacity, which mainly depends on the irreversible consumption reactions between the internal chemical systems of the battery. The phenomenon of self discharge is inevitable in all lithium-ion batteries. The capacity loss caused by self discharge can be divided into two categories: reversible and irreversible: reversible refers to the portion of capacity that can be recovered when charging a lithium-ion battery, and irreversible loss refers to the unrecoverable capacity. It is necessary for battery manufacturers and battery users to reduce battery capacity loss after long-term storage.

  2) Internal resistance

  The internal resistance of a battery refers to the resistance between the positive and negative ends, which is the sum of the resistances of the current collector, electrode active material, separator, electrolyte, conductive handle, and terminal. For lithium-ion batteries, the smaller the internal resistance, the smaller the voltage occupied by the battery during discharge, and the more energy it can output. But for batteries stored for a long time, the resistance often increases with increasing storage time. Exceeding a certain resistance can cause the battery to exceed the benchmark internally, leading to scrapping or degradation. Therefore, it is necessary to pay attention to the changes in resistance during long-term storage of the battery
