Lithium batteries generate electrical energy by the movement of lithium ions between the electrodes. This process of storing and releasing energy is accomplished through the insertion and extraction of lithium ions from the positive‑electrode active material into the negative‑electrode active material, without any accompanying chemical reactions—this is a defining characteristic of lithium‑ion batteries.
　　This characteristic of its battery reaction ensures that it will have a longer lifespan than conventional secondary batteries. Moreover, the wide range of available electrode materials is another key advantage. Coupled with the lithium‑ion battery’s inherent traits—compactness, light weight, and high voltage—careful material selection and structural design can simultaneously deliver high power output and high energy capacity. As a result, it is possible to tailor the battery’s architecture and performance to precisely meet specific application requirements, which constitutes one of the lithium‑ion battery’s major strengths.
　　A lithium-ion battery consists of a cathode active material serving as the oxidizing agent, an anode active material acting as the reducing agent, an electrolyte that facilitates lithium-ion transport, and a separator that prevents short circuits between the two electrodes. Below, using a typical lithium-ion battery as an example, we will outline the recommended storage conditions and important precautions.
　　Storage Environment Requirements and Precautions: Do not immerse the power battery assembly in water or rinse it with water. Do not expose the power battery assembly to fire or prolonged high‑temperature conditions; keep it well away from heat sources. Avoid storing or using the product in environments with high static electricity or strong electromagnetic radiation.
