What are the differences between high-quality
power lithium batteries and regular lithium batteries.
The power of new energy vehicles comes from lithium-ion batteries, which are actually a type of power source for road transportation vehicles. The main differences between it and ordinary lithium batteries are as follows:
1、 Different properties
Power lithium batteries refer to batteries that provide power for transportation vehicles, generally referring to small batteries that provide energy for portable electronic devices; A regular battery is a type of primary battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution, which is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries.
2、 Different battery capacities
In the case of all new batteries, test the battery capacity with a discharge meter. Generally, the capacity of power lithium batteries is around 1000-1500mAh; The capacity of ordinary batteries is above 2000mAh, and some can reach 3400mAh.
3、 Differences in voltage
The working voltage of general power lithium batteries is lower than that of general lithium batteries. The maximum charging voltage for lithium-ion batteries is generally 4.2V, while the maximum charging voltage for power lithium-ion batteries is around 3.65V. The nominal voltage of a typical lithium-ion battery is 3.7V, while the nominal voltage of a power lithium-ion battery is 3.2V.
4、 Different discharge power
A 4200mAh power lithium battery can discharge its energy in just a few minutes, but ordinary batteries cannot do so, so the discharge capacity of ordinary batteries is completely incomparable to that of power lithium batteries. The biggest difference between power lithium batteries and ordinary batteries is that they have a high discharge power and specific energy. Due to the important use of power batteries for vehicle energy supply, they have higher discharge power compared to ordinary batteries.
5、 Different applications
The batteries that provide driving power for electric vehicles are called power
lithium batteries, including traditional lead-acid batteries, nickel hydrogen batteries, and emerging lithium-ion power electric lithium-ion batteries, which are divided into power type lithium-ion batteries (hybrid vehicles) and energy type lithium-ion batteries (pure electric vehicles); The lithium-ion batteries used in consumer electronics products such as mobile phones and laptops are generally referred to as lithium-ion batteries to distinguish them from the power lithium-ion batteries used in electric vehicles.
