How to store lithium-ion batteries without long-term discharge and charge
Lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the production, storage and use of lithium metal have very high environmental requirements. Therefore, lithium-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have now become the mainstream.
Lithium ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, only a few companies in a few countries are processing this lithium metal battery.
Lithium-ion battery: It is a secondary battery (rechargeable battery) that relies heavily on the movement of lithium ions between the positive electrode and the negative electrode to work. During charging and discharging, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ deintercalates from the positive electrode and intercalates into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.
Lithium-based batteries are divided into lithium-ion batteries and lithium-ion batteries. Cell phones and laptops use lithium-ion batteries, which are commonly referred to as lithium-ion batteries. Batteries generally use materials containing lithium as electrodes, which are representative of modern high-performance batteries. The real lithium-ion battery is rarely used in daily electronic products due to its high risk.
The newly-purchased lithium-ion battery will have a little power, so when the user gets the battery, the user can use it straight, use up the remaining power and recharge it. After 2 to 3 times of normal use, the lithium-ion battery activity can be fully activated. . Here is a special reminder: Don’t misbelieve the rumors from the salesperson or the Internet, the new lithium-ion battery needs to be activated for up to 12 hours when it is used for the first time.
Lithium-ion batteries do not have a memory effect and can be charged as they are used, but it should be noted that lithium-ion batteries cannot be over-discharged. Over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, it will start charging immediately.
