    Difference between lithium battery and lead acid battery May 05, 2024
    The difference between lead-acid batteries and lithium batteries lies in their working principle, energy density, self discharge rate, cycle life, and environmental impact.   1. Working principle   The working principle of lead-acid batteries is based on chemical reactions, which generate current through the oxidation-reduction reaction between active substances in sulfuric acid solution; Lithium ion batteries rely on the movement of lithium ions between the positive and negative electrodes to generate current.   2. Energy density   The energy density of lead-acid batteries is relatively low, about 0.5Wh/g, which means it requires a larger volume or weight to store the same amount of electricity; Lithium ion batteries have a higher energy density, typically 2-3Wh/g, allowing for smaller and lighter storage of the same amount of electricity.   3. Self discharge rate   The self discharge rate of lead-acid batteries is relatively high, and they will quickly lose power when not in use; The self discharge rate of lithium-ion batteries is relatively low, and they can maintain a better state of charge even if not used for a long time.   4. Cycle life   The cycle life of lead-acid batteries is relatively short, usually 300-500 cycles, after which their performance will significantly decrease; Lithium ion batteries have a long cycle life, reaching over 1000-2000 cycles.   5. Environmental impact   The manufacturing and treatment process of lead-acid batteries involves the use and emission of heavy metal lead, which poses a pollution risk to the environment; In contrast, the production process of lithium-ion batteries also produces some harmful substances, but they are easier to recycle and reuse, and have a relatively small impact on the environment.   Whether it is lead-acid batteries or lithium-ion batteries, the choice of which type depends on the specific application scenario and requirements. During the use of these two types of batteries, regular maintenance and proper handling should be taken into account to reduce their impact on the environment and extend their
