Advantages of Lithium Polymer Battery Technology
Enhanced Safety Performance
Our polymer lithium batteries feature aluminum-plastic flexible packaging, unlike traditional metal-cased liquid batteries. This design ensures maximum safety - while liquid batteries may explode under hazardous conditions, polymer batteries only vent gas at most.
Ultra-Thin Profile Design
Achieve unprecedented thinness with batteries that can be as slim as credit cards. Unlike conventional lithium batteries limited to 3.6mm thickness, our polymer cells can be manufactured thinner than 1mm to meet modern device requirements.
Lightweight Construction
Polymer electrolytes eliminate the need for heavy metal protective casings. Our batteries are 40% lighter than equivalent steel-shell lithium batteries and 20% lighter than aluminum-shell alternatives.
Superior Capacity
Experience 10-15% higher capacity compared to same-sized steel-shell batteries and 5-10% more than aluminum-shell versions. The preferred choice for advanced electronic devices requiring extended runtime.
Low Internal Resistance
With internal resistance as low as 35MΩ, our polymer batteries significantly reduce self-consumption and extend device standby time. Ideal for high-drain applications including remote control models.
Customizable Form Factors
Break free from standard shapes with economically produced custom dimensions. We can adjust battery thickness and develop new models to perfectly fit your device's internal space constraints.
