The ternary polymer lithium battery is a lithium battery based on a polymer electrolyte, and the positive electrode material is lithium nickel-cobalt manganate (Li(NiCoMn)O2) or lithium nickel-cobalt aluminate. The 18650 lithium battery is a very common type of lithium battery, where 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery.
Ternary polymer lithium batteries and 18650 lithium batteries are different types of lithium batteries, each with some advantages and characteristics. Here's how they compare:
Ternary polymer lithium battery:
High energy density: ternary polymer lithium batteries have a higher energy density, which can provide a longer service life.
High safety: ternary polymer lithium batteries are relatively safe because they use solid polymer electrolytes, reducing the risk of fire and explosion.
Thin design: Due to their thin design, they are suitable for some devices with high volume requirements, such as smartphones, tablets, etc.
18650 Lithium battery:
High power density: 18650 lithium battery has relatively high power density, can provide greater discharge capacity, suitable for some high-power demand equipment, such as laptops, power tools and so on.
Mature technology and market: 18650 lithium batteries have existed for a long time, the technology is relatively mature, and there is a wider range of choices on the market.
So determining which is better depends on your specific needs. If you need high energy density and thin design, as well as high safety, then ternary polymer lithium batteries may be more suitable. If you need higher power density and greater discharge capacity, or you are more focused on mature technology and market options, then the 18650 lithium battery may be more suitable.
