    What is open circuit voltage and what is the capacity of a battery?

    Oct , 17 2022
    What is the nominal voltage? The nominal voltage of the battery refers to the voltage displayed during normal operation. The nominal voltage of the secondary nickel-cadmium nickel-hydrogen battery is 1.2V; the nominal voltage of the secondary lithium battery is 3.6V. What is open circuit voltage? The open circuit voltage refers to the potential difference between the positive and negative electrod...

    Overview of Si-based anode materials

    Oct , 17 2022
    The theoretical specific capacity of Si is as high as 4200mAh/g, which is 10 times higher than the theoretical specific capacity of graphite; the lithium intercalation potential of Si is low, which is 0.37mV Li/Li+; and Si is the second most abundant element on the earth, which is not harmful to the environment. Destruction will occur, and the production process of nano-silicon is mature and low-c...

    Failure causes of lithium battery- Failure in other aspects

    Oct , 08 2022
    Due to the low intrinsic conductivity of LiFePO4, the morphology and size of the material itself, as well as the influence of conductive agents and binders, are easily manifested. Discussing the two contradictory factors of size and carbon coating , it is found that the impedance of LiFePO4 electrode is only related to the average particle size. The anti-site defect inside LiFePO4 (Fe occupies Li ...

    Failure causes of lithium battery- Failure during charging and discharging

    Oct , 08 2022
    The battery is often overcharged in the process of use. Relatively speaking, the overdischarge situation is less. The heat released during the overcharge or overdischarge process is easy to accumulate inside the battery, which will further increase the battery temperature. , affecting the service life of the battery and increasing the possibility of the battery catching fire or exploding. Even und...

    Failure causes of lithium battery- Failure during recycling

    Oct , 08 2022
    The battery is generally exothermic during use, so the effect of temperature is very important. In addition, road conditions, usage, ambient temperature, etc. will have different effects. The capacity loss of LiFePO4 power batteries during cycling is generally considered to be caused by the loss of active lithium ions. The research shows that the aging of LiFePO4 power battery during cycling is ma...

    Failure causes of lithium battery- Failure during shelving

    Oct , 08 2022
    In the service life of the power battery, most of the time is in a state of shelving. Generally, after a long period of shelving, the performance of the battery will decline, generally showing an increase in internal resistance, a decrease in voltage, and a decrease in discharge capacity. There are many factors that cause the degradation of battery performance, among which temperature, state of ch...

    Key Factors in Choosing the Right UPS

    Sep , 26 2022
    You rely on your UPS system for backup if your power goes out, right? But does your UPS have your back? That is, will it provide a bridge of power long enough for what you need? At the very least you will want to save your data and perform a safe shutdown. Your UPS backup battery will only provide power for a set amount of time, known as runtime. In this article, we will provide a step-by-step app...
