What are the differences between power lithium batteries and ordinary lithium batteries?



The power of new energy vehicles comes from power lithium battery, which is actually a power source for supplying power source of road transportation vehicles. The main differences between it and ordinary lithium batteries are as follows:

First, the nature of different

Power lithium battery refers to the supply of power for the means of transportation battery, generally related to the supply of energy for portable electronic devices, small batteries; and ordinary batteries is a lithium metal or lithium alloy as the anode material, the use of non-aqueous electrolyte solution of the primary battery, and rechargeable batteries lithium-ion batteries and lithium-ion polymer batteries are not the same.

Second, the battery capacity is different

In the case of new batteries, with a discharge meter to test the battery capacity, the general power lithium battery capacity of 1000-1500mAh or so; while the capacity of ordinary batteries in 2000mAh or more, some can reach 3400mAh.

Third, the difference in voltage

General power lithium battery operating voltage is lower than the general lithium battery voltage. General lithium-ion battery charging voltage is up to 4.2V, the highest charging voltage of lithium power battery is about 3.65V. General lithium-ion battery nominal voltage is 3.7V, power lithium-ion battery nominal voltage is 3.2V.

Fourth, the discharge power is different

A 4200mAh power lithium batteries can be discharged in just a few minutes, but ordinary batteries can not do, so the discharge power of ordinary batteries can not be compared with power lithium batteries. The biggest difference between power lithium batteries and ordinary batteries lies in its high discharge power and high specific energy. Due to the important use of power battery for automotive energy supply, so compared to ordinary batteries to have a higher discharge power.

Five, different applications

Electric vehicles for the supply of driving power for the battery is called power lithium batteries, including traditional lead-acid batteries, nickel-metal hydride batteries, as well as emerging lithium-ion power lithium-ion batteries, divided into power lithium-ion power batteries (hybrid vehicles) and energy lithium-ion power batteries (pure electric vehicles); cell phones, laptops and other consumer electronics products used in the lithium-ion battery is generally referred to as lithium-ion batteries, in order to differentiate the power lithium-ion battery for electric vehicles, the power lithium-ion battery for electric vehicles. Power lithium batteries for electric vehicles.
