Four advantages of polymer lithium battery

1. Good safety performance. Polymer lithium batteries choose aluminum-plastic soft packaging in structure, which is different from liquid batteries with metal shells. Once there is a safety hazard, lithium batteries simply explode, while polymer batteries can only blow up, and at most burn. 2. The small thickness can be made thinner and ultra-thin, the thickness can reach below 1mm, and it can be assembled into a credit card. The thickness of ordinary liquid lithium batteries is less than 3.6mm and there is a technical bottleneck, while the capacity of 18650 batteries is standardized. 3. Light weight and large capacity polymer electrolyte battery does not need metal casing to protect the packaging, so under the same capacity, it is 40% lighter than steel lithium battery and 20% lighter than aluminum battery. When the volume is generally larger, the capacity of the polymer battery is larger, about 30% higher. 4. Customizable shape polymer battery can add or reduce the thickness of the battery according to actual needs. For example, the trapezoidal polymer battery is selected for brand-name new notebooks to make full use of the internal space.
