The Difference Between Power Lithium Battery And Ordinary Lithium Battery


First of all, nature is different.

A power battery is a battery that powers a vehicle, often compared to the small batteries that power portable electronic devices. Common batteries use lithium metal or lithium alloy as the anode material, using a non-aqueous electrolyte solution. The primary battery, and rechargeable battery lithium-ion battery is not the same as lithium-ion polymer battery.

Second, the battery capacity is different.

In the case of a new battery, the battery capacity is tested by a discharge meter. The capacity of a typical power battery is about 1000-1500 mah; ordinary batteries have a capacity of more than 2,000mah, and some can reach 3,400mah.

Third, the discharge power is different.

A 4200mAh power battery can discharge in a few minutes, but ordinary batteries can't do that, so the discharge capacity of ordinary batteries is not comparable to that of power batteries. The biggest difference between power battery and ordinary battery is that discharge power is large, higher than energy. Since power batteries are mainly used for automotive energy supply, they have higher discharge power than ordinary batteries.

Fourth, the application is different.

The batteries that power electric vehicles are called power batteries and include traditional lead-acid batteries, nickel metal hydride batteries and the emerging lithium-ion powered lithium batteries, which are divided into power-type power batteries (hybrid electric vehicles) and energy-type power batteries. (pure electric vehicle);  lithium-ion batteries used in consumer electronics such as mobile phones and laptops are commonly referred to as lithium-ion batteries, which are different from those used in electric cars.

It is the power battery discharge rate is large, it is easy to cause fire and other safety problems. At the same time, the design has special safety protection.

The safety problems with ordinary batteries are not obvious.
