The maintenance and long-term method of lithium-ion battery

The storage of lithium-ion battery

"Lithium battery" is a kind of battery that uses lithium metal or lithium alloy as anode materials, and has non-aqueous electrolyte solution. Lithium battery is researched by GilbertN Lewis in 1912. In the 1970 s, M.S.Whittingham came out of his theory and began to study lithium ion battery. The lively characteristics of lithium metal have very severe environment requirements of processing, storage and usage. Therefore, lithium battery cannot be widely used for a long time. As the development of science and technology, the lithium battery has now become the mainstream.

Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium-ion battery does not contain lithium metal state, and can be recharged. The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.

Lithium ion battery: a secondary battery (rechargeable batteries), it is mainly rely on lithium ions move between the positive and negative to work. In the process of charging and discharging, Li + embedded back and forth between the two electrodes and embedded off: when charging, Li + embedded from the anode, after anode, electrolyte embedded in the cathode in the rich lithium state; Discharge is the opposite.

Lithium batteries are divided into lithium battery and lithium ion batteries. Mobile phones and laptops are lithium ion battery, usually people commonly known as lithium battery. Materials containing lithium batteries are used as the electrode, is the representative of modern high-performance batteries. But the real lithium battery, because of the large risk rarely applied in the daily electronic products.

Newly purchased lithium batteries because of how much power a little, as a result, users get a battery can be used directly, the remaining battery recharging, after this 2 ~ 3 times of normal use and can fully activate the activity of lithium battery. Here special remind a bit: don't mistakenly salesman or rumors on the network, the new lithium battery was first used for up to 12 hours of activation.

Lithium battery no memory effect, can be in charge, but note that the lithium battery cannot excessive discharge, and excessive discharge can cause irreversible capacity loss. When the machine starts charging immediately remind when battery is low.

In everyday use, just filled the lithium battery to hold half a clock, electric performance is stable after use, otherwise it will affect battery performance.

Do not use the equipment, and be sure to remove the battery stored in a dry place.

Pay attention to the use environment of lithium-ion batteries, lithium battery temperature 0 ℃ ~ 45 ℃, lithium-ion battery discharge temperature was 20 ℃ ~ 60 ℃.

Not to mix the battery with metal objects, so as to avoid metal objects touch battery are the anode, cause short circuit, damage to the battery or even dangerous.

Don't knock, acupuncture, trample, modified, sun batteries, do not place the battery in the microwave, such as high pressure environment.

Use formal matching lithium battery charger to recharge the battery, do not use inferior or other types of battery chargers for li-ion batteries.

Lithium-ion batteries for a long time not to be filled with 50% ~ 80% of the battery, and from the instrument stored in a cool and dry environment, and every three months to charge batteries, in order to avoid the storage time is too long, the battery power is too low, caused by self-discharge irreversible capacity loss.

The self-discharge of lithium-ion batteries is influenced by environmental temperature and humidity. High temperature and wet temperature will accelerate the self-discharge of the battery, so it is suggested to take the battery in dry environment at 0 ℃ ~ 20 ℃.
