What are the factors that affect the performance of the lithium battery connecting terminals?

Discharge current

Discharge current, the impact on lithium batteries, different lithium batteries support different discharge rates, the same battery, under different discharge rates, the capacity retention rate is different, the higher the discharge rate, the smaller the discharge capacity, so in the selection of the lithium battery, attention should be paid to choosing the appropriate battery load current battery.

Charging current

What is the impact of charging current on lithium-ion power batteries? Lithium iron phosphate battery connection piece generally recommends a charging rate of 0.2C. For example, lithium battery is 10Ah, generally 2A charging current, and the application is a larger 0.5C charging. The larger the charging current, the smaller the actual load capacity, the less of the cycle life. To a certain extent, it is well known that most of the lithium-ion battery combustion accidents occur during the battery charging process.

Working temperature

Lithium battery connectors generally use conventional lithium batteries, the charging system temperature is 0~45 degrees, and the discharge ambient temperature is -20~60 degrees. At low temperature, lithium ions are not active enough, the temperature requirements are too high, and lithium ions are too active, so for lithium batteries, there is generally a temperature variation range and no clear working range. Lithium batteries have a high energy distribution density and a lot of storage and energy, but they are also fragile. They must be administered and used strictly in accordance with the manufacturer’s instructions. At low temperature, charging will cause lithium precipitation, and the battery will precipitate on the surface of the cathode material to form dendrites, pierce the positive electrode and the protective film of the positive electrode, and cause a short circuit inside the battery, causing heating, burning and even explosion. Lithium battery tab refers to a part of the space of a container or composite container, which contains electrolyte and metal electrodes to generate electric current and convert chemical energy into electrical energy. There are positives and there are some negatives. With the development of science and technology, batteries are often referred to as small devices that can generate electricity. Such as the use of solar cells. The main contents of battery performance parameter research include electromotive force, capacity, specific energy and resistance. Using the battery as the power source can obtain the long-term stability of voltage stability, current stability, power supply stability and not affected by external current. In addition, the battery system is simple in structure, convenient to carry, convenient to charge and discharge, not affected by external environmental climate and temperature, and has relatively stable and reliable performance. Lithium battery connectors play an important role in all aspects of modern social life.
