- Ultra-Thin Design: Can be manufactured thinner than 1mm, making them ideal for slim devices like modern mobile phones.
- Lightweight: 40% lighter than steel shell lithium batteries and 20% lighter than aluminum shell batteries of the same capacity.
- High Capacity: Offers 10-15% higher capacity than steel shell batteries and 5-10% higher than aluminum shell batteries of the same size.
- Low Internal Resistance: Internal resistance can be less than 35MΩ, reducing self-consumption and extending device standby time.
- Customizable Shape: Can be economically manufactured in custom sizes and shapes to maximize space utilization in devices.
