Lithium Battery Knowledge
UL is an independent product safety certification organization which, in conjunction with other organizations and industry experts, publishes consensus-based safety standards. For lithium batteries, key standards are: UL 1642 (Lithium Batteries) – This standard is used for testing lithium cells. UL2054 (Household and Commercial Batteries) – For lithium batteries, Battery packs tests are covered by UL 2054.
The CB Scheme is an international program for exchange and acceptance of product safety test results among participating laboratories and certification organizations around the world. The CB Scheme offers manufacturers a simplified way of obtaining multiple national safety certifications for their products.
IEC 62133-2:2017 is the most well-known standard for exporting lithium-ion battery, including those used in IT Equipment, GPS, wearable products, smartwatch, Bluetooth devices, wireless sensors, tools, laboratory, household and medical equipment.
For those who need to ship Lithium and Lithium ion batteries and the products which they power, there is much confusion around the testing requirements of UN 38.3. These tests are required by most transportation agencies globally, before such batteries may be offered for transport by air, ground, sea or rail.
18650 is the originator of lithium-ion battery--a standard lithium-ion battery model that Japan SONY Company set in order to save cost, 18 of which means diameter is 18mm, 65 means length is 65mm, 0 means cylindrical battery.
How long does the lithium-ion battery need to charge for the first time, and what is the correct charging method and discharge method for the lithium battery? What are the precautions for using lithium batteries? With these questions we look down.
In order to make full use of the energy efficiency of the lithium-ion battery, in the daily use and storage process, attention should be paid to the maintenance of the lithium-ion battery and the long-term storage of the lithium-ion battery, so the following will explain separately.
The 18650 means 18 mm in diameter and 65 mm in length. Generally, the 18650 battery is used in the industry. The common ones are used in laptop computer batteries and flashlights.
With the promotion of social energy conservation and environmental protection, more and more environmentally friendly products have been applied to the market. In the battery industry, the ternary lithium battery quickly occupied the market with numerous advantages and gradually replaced the traditional lead-acid battery. For the traditional battery, the ternary lithium battery has the advantages of long life, energy saving, no pollution, low maintenance cost, complete charge and discharge, light weight, etc. It is said that the life of the ternary lithium battery is long and to what extent?
Overcurrent and short circuit current
An overcurrent or short circuit is caused by an unknown cause (when the battery is discharged or the positive and negative electrodes are accidentally touched by metal). To ensure safety, it is necessary to stop the discharge immediately.
