What is the Reason for the Shortened Life of Lithium Batteries?

Jul. 01, 2020

As an 18650 3.7 v Battery Factory, share with you. One of the reasons for shortening the life of lithium batteries: the influence of internal factors of lithium batteries: Lithium batteries are also divided into two categories: non-rechargeable and rechargeable. Non-rechargeable batteries are called disposable batteries, which can only convert chemical energy into electrical energy at one time, and cannot restore electrical energy back to chemical energy (or the reduction performance is extremely poor). The rechargeable batteries are called secondary batteries (also called accumulators). It can convert electrical energy into chemical energy and store it. When in use, it can convert chemical energy into electrical energy. It is reversible, such as the main feature of electrical energy chemical energy lithium battery.

1. Side reaction of lithium battery;

2. Irreversible consumption of lithium battery active materials;

3. For large lithium batteries, the battery has a large operating current and slow heat dissipation, which is easy to cause damage to the battery structure;

4. If additional safety protection measures are added to the lithium battery, the power provided by the lithium battery needs to be maintained;

The second reason for shortening the life of lithium batteries: the influence of working factors

1. Improper working environment of lithium battery directly affects the length of life: lithium battery charging temperature is 0 ℃ ~ 45 ℃, lithium battery discharge temperature is -20 ℃ ~ 60 ℃;

2. During the charging and discharging of lithium batteries, avoid overcharging and overdischarging lithium batteries;

3. Avoid incorrect operation methods when working on lithium batteries: short circuit; Shenzhen lithium battery

4. Use a regular matching lithium battery charger to charge the battery.

5. Leave the newly charged lithium battery for half an hour and use it after the charging performance is stable, otherwise it will affect the battery performance.

The third reason for shortening the life of lithium batteries: the impact of non-working factors

1. When the digital product matching the lithium battery does not work, the lithium battery should be removed from the equipment and instrument products;

2. For long-term storage of lithium batteries, the lithium batteries need to be charged to 97% to 98% saturation, and the lithium batteries should be charged and discharged once for 3 to 6 months during storage;

3. The storage temperature of the lithium battery should be controlled in the space of 10°~25°; Shenzhen Lithium Battery

4. Do not knock, acupuncture, trample, modify, or expose the battery to sunlight, and do not place the battery in microwave, high voltage, etc. environments.
