Safe use and maintenance of lithium batteries

With the continuous development of science and technology, lithium batteries have become an indispensable part of our daily life. From mobile phones, laptops to electric vehicles, electric vehicles, etc., lithium batteries are more and more widely used. However, in the process of using lithium batteries, if you do not pay attention to safety and maintenance, it may bring some potential dangers. Therefore, this article will introduce the safe use and maintenance of lithium batteries to help you better understand and use lithium batteries correctly.

First, the basic concept and types of lithium batteries

A lithium battery is a battery made of lithium metal or lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution. Compared with traditional batteries, lithium batteries have the advantages of high energy density, low self-discharge rate, environmental protection and so on. Common types of lithium batteries are:

Single-use lithium batteries: lithium batteries used once, such as lithium button batteries, lithium manganese batteries, etc.

Secondary lithium battery: lithium battery that can be charged and discharged multiple times, such as batteries used in mobile phones, laptops, etc.

Power lithium battery: mainly used in electric vehicles, electric vehicles and other power equipment batteries.

Energy storage lithium battery: used in power storage, UPS and other fields.

Second, the safe use of lithium batteries

Do not overcharge: When the lithium battery is fully charged, it should immediately stop charging to avoid overcharging and damage.

Do not use in high temperature or humid environment: High temperature and humid environment can easily lead to the chemical reaction inside the lithium battery, thereby increasing the risk of the battery.

Use the original charger: do not use the non-original charger to charge the lithium battery, so as to avoid the danger caused by the mismatch of voltage and current.

Avoid metal touching the positive and negative electrodes: Metal substances in lithium batteries have the risk of electric shock, and should avoid touching the positive and negative electrodes of the battery with metal objects.

Do not remove the battery at will: do not remove the lithium battery at will, so as to avoid battery damage or electric shock risk due to improper operation.

Third, the maintenance method of lithium battery

Regular charging and discharging: In order to ensure the life of the lithium battery, it should be regularly charged and discharged. It is generally recommended to carry out a charge and discharge cycle about one month.

Clean the dust of the shell: Regularly clean the dust of the lithium battery shell to maintain the heat dissipation performance and performance of the battery.

Avoid power loss storage: lithium batteries that are not used for a long time should maintain a certain amount of power to avoid damage due to power loss.

Use the appropriate temperature environment: high and low temperatures will affect the life of lithium batteries, so attention should be paid to maintaining the appropriate temperature environment during use.

Storage: Fully charged lithium batteries should be stored in a cool and dry place, avoid direct sunlight and wet environment. In addition, avoid storing lithium batteries with metal items to avoid the risk of electric shock.

Fourth, practical skills sharing

How to deal with sudden drop in power: If the battery power suddenly drops in normal use, first stop using, and check whether the charger and battery are normal in time. If there is any problem, contact professional maintenance personnel to deal with it and avoid danger.

How to judge the expiration of battery life: When it is found that the lithium battery charge and discharge time is significantly shortened, and the heat is serious when charging, it may be a precursor to the expiration of the battery life. At this time, the battery should be sent to repair or replace the new battery in time to avoid danger.

5. Precautions

Do not attempt to disassemble the battery: under any circumstances, do not attempt to disassemble the lithium battery yourself to avoid danger.

Pay attention to safe storage: Fully charged lithium batteries should be stored in a cool and dry place, away from direct sunlight and humid environment. At the same time, avoid storing lithium batteries with metal objects.

Use original accessories: In the process of charging and discharging, the original charger and data cable should be used to avoid damage or danger to the battery due to mismatching accessories.

Understand the safe use knowledge: Before using lithium batteries, understand the relevant safe use knowledge, and strictly follow the requirements of the operation. Especially for lithium batteries of electric vehicles, electric vehicles and other power equipment, more attention should be paid to safe use and maintenance.

In short, although lithium batteries have many advantages, they also need to pay attention to safety and standard operation during use and maintenance. Only the correct use and maintenance of lithium batteries can give full play to its advantages, extend its service life, and ensure the safety of our lives and property.
