    What does lithium battery cell mean?

    2019-04-22 08:33:40 0

    A typical lithium battery generally consists of two parts: a lithium battery cell + a control chip.

     

    The lithium battery cell is the carrier for storing electricity, and the control chip is an important part of controlling the operation of the lithium battery such as charging and discharging. If the lithium battery does not have a control chip and only has a battery cell, then the current and voltage cannot be controlled during charging and discharging, and it may burn or even explode in an instant. Therefore, the control chip is a necessary configuration for safe use of lithium batteries. Of course, some of the appliances have their own chips, you can directly use the lithium battery cell power supply, such as some of the self-contained protection chip using 18650 battery (lithium battery cell) strong light flashlight.

     

    Refers to a single electrochemical cell containing positive and negative electrodes, generally not used directly. Different from the battery contains protective circuit and housing, it can be used directly.

     

    The composition of the lithium ion secondary rechargeable battery is such that: the cell + protection circuit board. The rechargeable battery removal protection board is the battery cell. It is the power storage part of the rechargeable battery. The quality of the battery cell directly determines the quality of the rechargeable battery.

     

    The mobile phone board removes the outer casing, and then removes the protective circuit board in the electric board to leave the lithium battery cell.

     

    The battery cell is divided into three types: aluminum shell battery cell, soft battery cell (also known as "polymer battery cell"), and cylindrical battery cell. Generally, the mobile phone battery adopts an aluminum-clad battery cell, and digital products such as Bluetooth adopt a soft-package battery cell, and the battery of the notebook computer adopts a series-parallel combination of cylindrical batteries cell.
