Due to the strong activity and high energy density of lithium, there are many hidden dangers to the safety of lithium-ion batteries. Lithium-ion battery manufacturers must fully consider the safety during transportation, storage, and use when designing a lithium-ion battery. From the selection of raw materials to the production process, the finished product’s safety must be considered. When a cell is produced, we need to use the specified lithium-ion battery testing equipment to test it according to the corresponding standards to check whether the tested battery has reached the original design goal.
With the wide application of lithium-ion batteries in mobile communications, electronic appliances, electric vehicles, and other fields, safety incidents occur from time to time, so the safety performance of lithium-ion batteries has always attracted much attention. Lithium-ion batteries need to be evaluated and tested for safety performance before application so as to avoid safety risks that may occur during use, resulting in dangers such as battery short-circuit or explosion, which may lead to personal injury and property damage. If we perform all safety tests on lithium-ion batteries before they leave the factory, it can effectively ensure the safety of lithium-ion batteries in use, transportation, and storage from the source.
We test on lithium-ion batteries for overcharge, over-discharge, short circuit, etc., to determine whether the protection device of the battery can take timely action to cut off the current loop and prevent the occurrence of dangerous events when the lithium-ion battery is abnormal. By testing the lithium-ion battery for vibration, shock, low pressure, temperature cycles, etc., we can know whether it can normally work in different external environments and whether abnormal and unsafe events will occur, and then determine their reliability and stability.
In a word, battery safety accidents can be effectively reduced by doing lithium-ion battery safety tests.
In today’s globalized world, if you want to achieve long-distance transportation between countries, air transportation or ocean shipping is the primary option. For the transportation of lithium batteries or products with lithium-ion batteries, whether by sea or air, the UN38.3 test report must be issued. The shipping company will not accept your shipment if you do not have this report. And UN38.3 is the test standard for lithium battery safety, which covers 8 test items. Therefore, lithium-ion battery safety testing is a necessary precondition for your batteries or products containing batteries to achieve international transportation.
All lithium-ion battery safety test items are derived from corresponding standards, such as IEC, UL, ISO, etc. The makers of these standards are all internationally renowned institutions or organizations. Their popularity is well known in countries all over the world. If your product can pass these test standards, it means that the product quality has been verified, and the market will give you more trust and support. A safety inspection certificate is a business card for your product, which can effectively improve your corporate image.
