What Are The Advantages Of Polymer Lithium Batteries?

1. Good safety performance:
The structure of polymer lithium-ion batteries uses aluminum-plastic soft packaging, which is different from the metal casing of liquid batteries. Once a safety hazard occurs, liquid batteries are prone to explosion, while polymer batteries will only bulge at most.
2. Small thickness, can be made thinner:
Ultra-thin, the battery can be built into a credit card. Ordinary liquid lithium batteries use the method of first making the outer casing and then plugging the positive and negative electrode materials. There is a technical bottleneck when the thickness is less than 3.6mm. This problem does not exist for polymer batteries, and the thickness can be less than 1mm.
3.Light weight:
Batteries using polymer electrolytes do not require a metal shell as a protective outer packaging. Polymer batteries are 40% lighter than steel-cased lithium batteries of the same capacity and 20% lighter than aluminum-cased batteries.
4. Large capacity:
Polymer batteries have a capacity 10 to 15% higher than steel shell batteries of the same size and 5 to 10% higher than aluminum shell batteries.
5. Small internal resistance:
The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. At present, the internal resistance of domestic polymer batteries can even be below 35mΩ, which greatly reduces the battery's self-consumption and extends the standby time of electrical appliances. It can reach In line with international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models and has become the most promising product to replace nickel-metal hydride batteries.
6. The shape can be customized:
Manufacturers are not limited to standard shapes and can economically make them the right size. Polymer batteries can add or reduce the thickness of the battery cells according to customer needs, and develop new battery cell models. They are cheap and have a short mold opening cycle. Some can even be customized according to the shape and quantity of the appliance to make full use of the battery shell space and improve the battery quality. capacity.
7. Good discharge characteristics:
Polymer batteries use colloidal electrolytes, which have smooth discharge characteristics and a higher discharge platform than liquid electrolytes.
8. The protection board design is simple:
Due to the use of polymer materials, the battery core does not catch fire or explode, and the battery core itself is sufficiently safe. Therefore, the protection circuit design of polymer batteries can consider omitting pTCs and fuses, thereby saving battery costs.
