Top Lithium Battery Manufacturers

The development of new energy vehicle power battery systems involves materials, chemistry, mechanics, thermodynamics, heat transfer, fluid mechanics, electricity, systems and control, and its key technologies include battery assembly technology, thermal management technology, power management technology and safety. management technology, etc. The vehicle power battery system technology has become a bottleneck for the popularization of electric vehicles, and it is necessary to explore and make breakthroughs in material development, battery design, manufacturing, system integration, and business models.

Lithium-ion battery is a type of rechargeable battery that uses graphite or other carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. During the charging and discharging process, there is no metal lithium, only lithium ions, so lithium batteries are also called lithium-ion batteries. .

Lithium-ion battery has high working voltage, stable discharge curve, high energy density (weight specific energy is 110~160Wh/kg), small size, light weight and long cycle life (after 500 cycles, the capacity remains above 80%); No memory effect, small self-discharge; wide operating temperature range (0~45°C for charging, -20~60°C for discharge); green and environmentally friendly, free of toxic metal elements such as lead, cadmium, and mercury.

According to the different cathode materials, lithium ion batteries are divided into cobalt oxide lithium ion batteries, manganate lithium ion batteries, ternary material lithium ion batteries, and lithium iron phosphate batteries.

According to the shape of the cell, lithium-ion batteries are divided into cylindrical lithium-ion batteries, square lithium-ion batteries, and soft-pack polymer lithium-ion batteries.

Frequently Asked Questions (FAQs)

  • Why are the voltages inconsistent and individually low?
    Large self-discharge results in low voltage, and large cell self-discharge causes its voltage to drop faster than others. Low voltage can be eliminated by checking the voltage after storage.

    The voltage is low due to uneven charging. When the battery is charged after detection, the charging current of the battery is uneven due to the inconsistent contact resistance or the charging current of the detection cabinet. The voltage difference is small in short-term storage (12 hours), but the voltage difference is large in long-term storage. This low voltage has no quality problem and can be solved by charging. After charging during production, store it for more than 24 hours to measure the voltage.

  • Why do lithium batteries swell?
    The lithium battery expands when it is charged. When the lithium battery is charged, the lithium battery will naturally expand, but generally it does not exceed 0.1mm. However, overcharging will cause the electrolyte to decompose, the internal pressure will increase, and the lithium battery will expand.

    Expansion during processing is generally caused by abnormal processing (such as short circuit, overheating, etc.) that causes the electrolyte to decompose due to excessive heating inside, and the lithium battery expands.

  • The battery voltage is less than 3.6V
    Inaccurate sampling of the testing cabinet or instability of the testing cabinet causes the test platform to be low.

    The ambient temperature is too low, causing the platform to be low (the discharge platform is greatly affected by the ambient temperature).

  • Internal resistance is too large
    Due to the difference of detection equipment, if the detection accuracy is not enough or the contact electric group cannot be eliminated, the display internal resistance will be too large, and the principle of AC bridge method should be used to test the internal resistance instrument.

    If the storage time is too long, the lithium battery is stored too long, resulting in excessive capacity loss, internal passivation, and large internal resistance, which can be solved by charging and discharging activation.
