    Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

    Apr , 20 2024
    What impact will the lithium battery have after being put aside for a long time? When the lithium battery is idle, due to the nature of the battery itself, self-discharge, passivation of positive and negative electrode materials, electrolyte decomposition and other phenomena will occur. The instability of the negative SEI will lead to the rapid decline of the negative active substance, which is ea...

  • 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...

  • 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...
