The formation of 3C lithium batteries means that after the battery is manufactured, the positive and negative materials inside the battery core are activated by charge and discharge to improve self-discharge, charging performance- battery discharge and storage performance. Capacity classification refers to the evaluation of battery capacity by testing battery capacity and other electrical performance parameters after battery manufacturing. The formation and capacity division of 3C lithium batteries are completed by automated systems.
Why do 3C lithium batteries need to be formed and divided into different capacities? Because after the production of the single cell of the battery is completed, due to the constraints of the battery production process, the parameters in terms of capacity, voltage, current, internal resistance, etc. will change. are not itoherent. Therefore, the battery must do it. be formed and divided to maintain the consistency of the 3C lithium battery.
After the formation and capacity division of the 3C lithium battery is completed, its performance still needs to be tested. During the test, the shrapnel microneedle module can be used as a current transmission medium, which can. stabilize the connection. The performance tests of 3C lithium batteries include basic performance, safety performance, environmental performance and electrochemical performance. During the test, the shrapnel microneedle module can transmit current between 1-50A, with strong overcurrent capability and an average of 20W. The battery life can effectively improve the efficiency of testing 3C lithium batteries and ensuring efficient and safe testing.
What does a consumer battery mean?
EnAs an energy storage component, lithium-ion batteries are important safety components in many electronic products. In order to ensure the safety of lithium batteries for electronic products, improve the production management system capabilities of manufacturing enterprises, and promote and standardize the development of the industry, the China Quality Certification Center ( abbreviation: CQC) formulated GB31241-2014 "Lithium-ion batteries and battery packs for portable electronic products "Safety requirements" and certification implementation. Therefore, lithium batteries require 3C certification. Lithium batteries that have passed 3C certification must be tested before being used in consumer electronics and digital products such as mobile phones, tablets and notebooks The average life of o-burst microneedle modules.high current bus is greater than 20W. of 3C Due to the high frequency testing requirements of lithium batteries, not only can they be used continuously, but the self-cleaning design of the shrapnel head can also prevent shrapnel from contamination, ensuring long-term stability of the test. During testing, the shrapnel microneedle module uses different head shapes to contact different test points, which is beneficial to current conduction and signal transmission.
Consumer batteries refer to the use of 3C products(for example: mobile phones, tablets, laptops >etc.) Typical CapacityLithium-ion batteriesmade from lithium-nickel-cobalt manganate, lithium manganate and other material systems. The consumer lithium battery is a primary batteryre which uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. High-end consumer batteries use the most advanced technologies and materials.
Consumer lithium-ion batteries appeared at the beginning of the lithium-ion battery industry and continued to develop.It has always occupied an important position. In recent years, with the improvement of national economic level and residents' consumption power, China's demand for consumer electronic products has continued to grow, which has laid a solid application foundation for the development of the consumer lithium-ion battery industry. At present, China's mainstream lithium-ion batteries are mainly used in notebook computers.s, tablets, smartphones, consumer drones, Bluetooth headsets, wearable devices, smart speakers and other fields.
Characteristics and applications of consumer batteries:
They have the characteristics of high specific energy, low internal resistance, low self-discharge and high safety performance. , and is used in mobile applications in power supply, mobile communications and other fields, the discharge rate is generally less than 1C. Safety should be considered when applying 3C lithium batteries. Therefore, the production of 3C lithium batteries requires testing. During testing, high current shrapnel microneedle modules can generally be used for connection, so that current can flow through the. same material body and the resistanceance is constant to ensure the stability of the test.
