(1) At present, tablet computers have been widely used. Online education, online office and audio-visual entertainment all need them. Notebook computers are gradually replacing desktop computers, which are cheap, easy to carry and convenient to move, and are popular with consumers. The market growth of consumer electronics products determines the development of 3C lithium batteries. The rise of emerging electronic products has also injected new vitality into the 3C lithium battery market. In the future, the penetration rate of flexible packaging lithium batteries in the 3C field will reach about 80%, and there is still much room for improvement.

(2) The development of high-end flagship mobile phones, folding screen mobile phones and smart wearable devices is the main body to promote the growth of 3C lithium batteries. 3C lithium battery will also develop towards large capacity, high magnification and flexible battery. In the production process of 3C lithium battery, its performance has always been concerned. For example, for the use safety, reliability and service life of 3C lithium battery, consumers expect not only the appearance of high-performance battery, but also the guarantee of lithium battery performance.

(3) The performance of 3C lithium battery needs to be verified through testing, which is an essential item in the manufacturing process. The quality of batteries must be strictly controlled to prevent inferior batteries from entering the market and affecting the use safety. The battery test module can be used for 3C lithium battery test to ensure the stability of battery test, thus improving the test efficiency of 3C lithium battery. KZT high current spring chip micro pin module has connection performance. It can transmit large current in the 3C lithium battery test, and can also handle battery connectors with small spacing to make contacts more stable.

(4) The application of 3C lithium battery is inseparable from the connection of BTB connector. The internal spacing of electronic products is small, and the space of BTB connector is very small. Therefore, in the 3C lithium battery test, the battery test module that can adapt to the field of small spacing - high current spring sheet micro needle module should be used. The reason is that the pogopin probe module can not adapt to the small spacing, and the pins are often stuck and broken, resulting in poor performance, which is not conducive to the stability of the 3C lithium battery test. The minimum distance that the high current spring sheet micro needle module can withstand can reach 0.15 mm, the performance is stable and reliable, the connection function is strong, the needle is not easy to break, and the service life can reach more than 20 W times, which is conducive to the stability test of 3C lithium battery.

(5) The 3C lithium battery test needs to transmit high current, and the pogopin probe module cannot pass the high current test. It can only withstand 1A current and is basically unstable. Therefore, it is no longer applicable to testing. The high current spring sheet micro needle module can withstand up to 50A current in the high current test. The over-current is stable. The current flows in the same material, and there is basically no current attenuation. High overall accuracy, low impedance, and stable response to 3C lithium battery test
