How to distinguish power lithium-ion batteries from ordinary lithium-ion batteries

How to distinguish between power-type lithium-ion batteries and ordinary lithium-ion batteries 1. The difference in power The biggest difference between power-type lithium-ion batteries and ordinary batteries is that they have high discharge power and high specific energy. Since the important purpose of power batteries is vehicle energy supply, they have higher discharge power than ordinary batteries. 2. The difference in appearance. Power lithium battery: The battery has thick pole pieces and thick diaphragm, which can withstand the discharge rate of 12C-50C, but the capacity is small. Ordinary battery: It is the so-called capacity battery. The diaphragm is small and cannot generally withstand 2.5C discharge at the maximum. 3, the difference in voltage The operating voltage of the general power lithium battery is lower than that of the ordinary lithium ion battery. The maximum charging voltage of ordinary lithium-ion batteries is 4.2V, and the maximum charging voltage of power lithium-ion batteries is about 3.65V. The nominal voltage of ordinary lithium-ion batteries is 3.7V, and the nominal voltage of power lithium-ion batteries is 3.2V. 4. Power lithium-ion batteries with different properties refer to batteries that supply power for transportation, generally related to small batteries that supply energy for portable electronic devices; while ordinary lithium-ion batteries are a kind of lithium-ion metal or lithium-ion battery. The alloy is the negative electrode material, and the primary battery using non-aqueous electrolyte solution is different from the rechargeable battery lithium ion battery and lithium polymer battery.
