New lithium-ion battery activation method
Because lithium-ion batteries do not have a memory effect, they should not be activated. Do not charge new lithium-ion batteries for 10+ hours to activate their activity; activate them using normal charge/discharge methods. Lithium-ion batteries do not have a memory effect and can be charged at any time. The suggestion to periodically perform a full charge/discharge cycle is merely for calibrating the battery level monitoring devices on laptops and some high-end smartphones, and does not benefit the battery itself. For ordinary mobile phones and digital cameras that display approximate battery levels in segments, periodic full charge/discharge cycles should be completely avoided. Overcharging and over-discharging can cause significant damage to lithium-ion batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to standard times and methods, especially avoiding charging for more than 12 hours. Generally, the charging method described in the instruction manual is the standard charging method. Lithium-ion battery activation is accomplished through a capacity testing cabinet. Specifically, this involves: filling the lithium-ion battery casing with electrolyte, sealing, and then forming the battery. Some battery manufacturers activate the battery between the electrolyte filling and sealing process, while others activate it between the battery sealing and the formation and capacity testing process.
Methods for activating old lithium-ion batteries
First, discharge your phone by buying a universal charger with a discharge function. Then, wrap it in plastic wrap and place it in the refrigerator. After 5 minutes, take it out and let it return to room temperature. Then, fully charge and discharge it for 12 hours. After about 3 cycles, the battery performance will be significantly improved.
Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. The earliest lithium metal battery was proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MS Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. Therefore, lithium-ion batteries were not widely used for a long time. With the development of science and technology, lithium-ion batteries have now become mainstream.
Lithium-ion batteries can be broadly classified 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, the lithium metal battery, was developed in 1996. Its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to lithium-ion batteries. Due to its high technological requirements, only companies in a few countries currently produce lithium metal batteries.
Lithium-ion battery activation is a preparation process before lithium-ion batteries are put into normal use. In this sense, lithium-ion battery activation is a matter of production rather than use. Since it is a matter of production, lithium-ion batteries do not need to be activated from the date they leave the factory.
