What are the performance tests for lithium batteries?

　　1、 What is the micro electric flow range tester

　　(1) The current range of micro electric flow range testing equipment is from several milliamperes to several amperes, such as testing equipment with multiple ranges such as ImA, 2mA, SmA, lOmA, lOOmA, 500mA, lOOOmA, 1800mA, 3000mA, 5000mA, etc;

　　(2) The current range of high current range testing equipment is from several amperes to several hundred amperes, such as 10A, 20A, 40A, 60A, 100A and other specifications of testing equipment.

　　(3) Compared with other rechargeable batteries, lithium ion batteries have the advantages of high energy density, high voltage, long life, no memory effect, etc,

　　(4) In the future, with the further improvement of lithium-ion battery production process and battery performance, lithium-ion batteries will occupy the mainstream market in energy storage batteries, power lithium batteries and other fields;

　　2、 Methods for testing the quality of lithium ion battery equipment

　　(1) The fastest inspection method is to test the internal resistance and maximum discharge current. The lithium ion battery equipment with good quality has very small internal resistance and large maximum discharge current. A multimeter with a 20A measuring range is used to directly short circuit the two electrodes of the lithium ion battery. The current should generally be about 10A, or even higher, and can be maintained for a period of time. The relatively stable battery is a good battery.

　　(2) Look at the appearance; The fullness of the appearance, such as the lithium ion battery equipment of about 2000mAh, is relatively large. The workmanship is fine or the packaging is plump.

　　(3) Look at the hardness; The middle part of the lithium-ion battery device can be gently or moderately pinched. If the hardness is moderate and there is no soft squeezing feeling, the lithium-ion battery cell is a relatively high-quality battery cell.

　　(4) Look at the weight; Remove the outer package to see if the battery weight is heavy. If it is heavy, it belongs to a high-quality battery cell.

　　(5) In the process of charged operation of lithium ion battery equipment, if the battery poles do not burn after continuous discharge for about 10 minutes, it proves that the battery protection plate system is perfect. Generally, the quality of lithium ion battery equipment with high-quality protection plate is better than that of ordinary lithium ion battery equipment.

　　(5) There are many well-known manufacturers of lithium-ion battery performance testing systems abroad. Among the domestic representative manufacturers, the testing equipment for lithium-ion battery performance is widely praised and is far ahead in the battery testing industry.
