    FAQ

    Q1. What are the diferences betwee high C-rate and low C-rate lithium?

    polymer (Li-Po) batteries.
    In general, the diferences lie in the materials made of the positive & negative terminals, the area density design, the electrolyte ingredient, the septum data and the density of inside pieces.


    Q2. How is a Li-Po battery made?

    When a Li-Po battery is made, five main aspects should be considered carefully:

    (1). Battery Pack should have suficient strength, so that the polymer battery inside could be efectively protected from mechanical shocks;

    (2). The polymer cell should be fixedto the battery pack onits large surface area - no cell movement in the battery packshould be allowed;

    (3). No sharp edge components should be inside the packcontaining the polymer battery, and meanwhile, suficient insulation layer between wiring and the cell should be used to maintain multiple safety protection;

    (4). Ultrasonic welding is recommended for polymer tab connection to obtain low-resistance, high-reliability and light-weight properties;(5). Polymer packs shouldbe designed carefully so that no shear force is applied, and also, no heat is generated even when leakage ocurs for mishaps. PCM from electrolyte leakage should be isolated as perfectly as posible, and narrow distance between bare circuit patterns should be avoided.


    Q3. What gases are generated in the formation process. Are they dangerous?

    The generated gases include Co, CO2,H2, CH4 and so on. They are not dangerous because of low volume.


    Q4. Why do we need formation process?

    Organic solvents easily decompose on the negative electrodes during charging, leading to battery swelling, drop of cell capacity, and unsafety caused by activereaction. The purpose of the formation process is to form a solid layer called the solid electrolyte interphase (SEl), which is electrically insulating yet provides significant ionic conductivity. This interphase prevents further decomposition of the electrolyte after the second charging.


    Q5. Why do Li-Po batteries bloat/swell?
    The Li-Po batteries may bloat or swell due to the following reason:
    1. Overcharging:Normally, the maximum charge voltage is 4.2V for RC batteries. If the batteries were overcharged beyond 4.4V, electrolytic oxidation process would happen, which generates mass gas leading to battery swelling.
    2. Overheat:When discharging in high temperature or high C rate, the temperature of the inner part of the battery can be even higher, which gasify the electrolyte and results in swelling.
    3. Shot-circuit.:If short circuit happened, the cell voltage would drop very fast and the electrolyte would be reactive to generate gases, leading to battery swelling.
    4, Sealing:If sealed without proper processing, the battery cell would have water and air in, so that the electrolyte would be reactive to generate gases, leading to battery swelling.
