Which is better lithium polymer battery or lithium metal battery?

Lithium polymer batteries are good.

Because lithium polymer batteries are improved products of lithium ion batteries. Compared with currently popular lithium-ion batteries, it has the advantages of large capacity, small size (thin) and safety (will not explode). However, because it takes a long time to replace the entire industrial chain, its cost (cost) is currently relatively high, and it is only used in high-end digital products (ultra-thin laptops, etc. ).

Characteristics of polymer batteries

1. Good safety performance - flexible aluminum-plastic packaging does not explode.

2. The thickness is small and can be made even thinner - less than 1 mm.

3. Lightweight: 40% lighter than steel-cased lithium batteries of the same capacity and 20% lighter than baAluminum housing tterries.

4. Large Capacity - 10-15% higher capacity than same size steel cased lithium batteries.

5. The internal resistance is low - less than 10 mΩ, making it an ideal choice for high-rate discharge power supplies.

6. The shape can be customized - tailor-made according to customer needs, making full use of space and increasing capacity.

If the internal resistance of the lithium battery is too high or too low, the impact on the battery will be as follows:

1. high, the battery will heat up more during discharge

2. Low internal resistance and low power consumption.

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Lithium metal batteries have been proposed and studied forfirst by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
