Advantages of lithium ion battery:

High energy density: Compared with other battery technologies (such as nickel cadmium battery), lithium ion battery has a higher energy density and has the opportunity to increase capacity, for example, by adding more nickel to the cathode.

Small package size and weight: Lithium ion batteries are ideal for portable consumer products. Designers can choose to use prismatic packages, which are usually thinner than 19 mm, or lithium polymer packages, which are usually thinner than 5 mm. In addition to size advantages, weight is also reduced due to chemical properties (such as solid/gel electrolytes rather than liquid electrolytes) and the packaging used (such as foil).

Memory effect: Unlike nickel cadmium battery (NiCd), lithium ion battery will not be affected by memory effect. The memory effect occurs when the battery is partially used and then fully charged for a period of time, which leads to rapid discharge. In modern batteries, it is more likely that the board is blocked due to the voltage drop caused by repeated overcharging, which increases the internal resistance and reduces the battery voltage.

Low discharge rate: Compared with other rechargeable batteries, lithium-ion batteries have a low self discharge rate, which means they can not be used for a long time.

Fast charging: The charging speed of lithium ion battery is faster than that of other batteries, and the charging speed is twice that of hydrogen fuel power battery.

Strong adaptability to high and low temperatures: Lithium ion batteries have strong adaptability to high and low temperatures, and can be used at - 20 ℃ - 60 ℃, and can be used at - 45 ℃ through processing.
