Main Advantages
- High Energy Density and Lightweight Design: Utilizing soft-pack aluminum-plastic film packaging, lighter than traditional cylindrical batteries with a thickness of only 6.5mm, allowing flexible integration into various flat-designed products.
- Flexible Form Factor Customization: Lithium polymer technology supports micro-adjustments in size based on product internal space. The 654065 specification offers high supply chain versatility and cost-effectiveness.
- High Safety Performance: Soft-pack structure typically swells rather than explodes during thermal runaway, and does not leak, resulting in higher safety factor.
- Excellent Cycle Life: Standard products typically have a deep cycle life of over 500 cycles and low self-discharge rate (less than 5% per month).
Main Applications
- Smart Wearables and Audio Devices: High-end Bluetooth headphones, smart glasses, VR/AR headsets
- Portable Consumer Electronics: Power banks (ultra-thin), handheld game consoles and controllers, portable translators, reading pens
- Smart Home and IoT Terminals: Smart door locks, video intercoms
- Portable Beauty and Personal Care: Beauty devices, massage devices, and other personal care products
- Industrial and Medical: Handheld scanners, PDAs (Personal Digital Assistants), portable medical monitors
