  • Lithium battery life The reason for the slow charging speed

    Lithium battery life The reason for the slow charging speed

    Dec , 13 2024
    1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

  • Causes and methods of lithium battery life decline

    Causes and methods of lithium battery life decline

    Dec , 13 2024
    1. Battery aging: After multiple charge and discharge cycles, the chemical substances inside the lithium battery will gradually undergo irreversible changes. For example, the structure of the electrode material may be damaged when lithium ions are embedded and deembedded between the positive and negative electrodes. Taking the common lithium cobalt oxide cathode material as an example, with the in...

  • Causes of harmonics in rectifier equipment

    Causes of harmonics in rectifier equipment

    Mar , 21 2025
    1. Nonlinear characteristics   The diodes, thyristors and other power electronic devices in rectifier equipment have nonlinear voltammetry characteristics. Take the diode as an example, when the input AC voltage is in positive half circle, the diode is positive and the current can pass through; At the negative half cycle, the diode is reversed off and the current is almost zero. This characte...

  • How to choose the right lithium battery

    How to choose the right lithium battery

    Mar , 28 2025
    1. Identify application scenarios The purpose of lithium batteries directly affects parameter selection: Portable devices (mobile phones, drones, cameras): give priority to high energy density (such as ternary lithium batteries) and lightweight. Electric vehicles/power tools: require high discharge rate (C-rate) and long cycle life (such as lithium iron phosphate batteries). Energy storage systems...
