Comparison of the difference between power lithium ion battery and ordinary battery

Power lithium ion battery refers to the battery that supplies power for transportation, generally related to the small battery that supplies energy for portable electronic devices; while the ordinary battery is a kind of lithium metal or lithium alloy as the negative electrode material, using non-aqueous electrolyte solution The primary battery is different from the rechargeable lithium-ion battery and the lithium-ion polymer battery. The battery capacity is different. In the case of new batteries, use a discharge meter to test the battery capacity. Generally, the capacity of power lithium-ion batteries is about 1000-1500mAh; while the capacity of ordinary batteries is above 2000mAh, and some can reach 3400mAh. Discharge power is different. A 4200mAh power lithium-ion battery can discharge the power in just a few minutes, but ordinary batteries can't do it at all, so the discharge capacity of ordinary batteries is completely incomparable with power lithium-ion batteries. The biggest difference between a power lithium-ion battery and an ordinary battery is its large 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. The batteries that use different applications to provide driving power for electric vehicles are called power lithium-ion batteries, including traditional lead-acid batteries, nickel-metal hydride batteries, and emerging lithium-ion power lithium-ion batteries. They are divided into power-type power lithium-ion batteries (hybrid vehicles). ) And energy-type power lithium-ion batteries (pure electric vehicles); lithium batteries used in consumer electronic products such as mobile phones and notebook computers are generally collectively referred to as lithium batteries, which are different from power lithium-ion batteries for electric vehicles.
