  • 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...

  • 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...

  • Irreversible lithium evolution of LiFePO4 batteries at low temperatures and its effect on battery performance degradation

    Irreversible lithium evolution of LiFePO4 batteries at low temperatures and its effect on battery performance degradation

    Dec , 07 2024
    Lithium evolution is the main failure problem faced by lithium-ion batteries during low temperature charging. Due to the low diffusion rate of lithium ions in the solid phase of graphite particles and in the liquid phase of the electrolyte at low temperatures, the negative polarization increases during charging and lithium evolution occurs, and the precipitated lithium metal is divided into revers...

  • The characteristics and principle analysis of internal resistance of lithium battery

    The characteristics and principle analysis of internal resistance of lithium battery

    Jul , 12 2024
    The internal resistance of the battery is one of the most important characteristic parameters of the battery, which is an important parameter to characterize the battery life and the operating state of the battery, and an important symbol to measure the difficulty of the transmission of electrons and ions in the electrode. The internal resistance also reflects the health of the battery. The intern...

  • What is the impact of low temperature on lithium batteries and solutions

    What is the impact of low temperature on lithium batteries and solutions

    Apr , 20 2024
    The use of lithium batteries in low battery temperature environments is limited. In addition to a severe drop in discharge capacity, lithium batteries cannot be charged when the battery temperature is low. When the battery is charged at low temperature, the lithium ion embedment on the battery graphite electrode and the lithium plating reaction exist simultaneously and compete with each other. Und...
