smaller, smarter and more powerful than ever before. From advanced fitness trackers and health monitors to AR
glasses and industrial wearables, these compact systems are redefining human–machine interaction.
Yet, behind every great wearable innovation lies one critical enabler — the battery.At PKNERGY, we develop lithium battery solutions specifically designed to power the next generation of smart
wearables, where compactness, performance and reliability must coexist. With our experience in
custom lithium polymer battery design and
ultra-thin batteries for wearables, we help brands turn creative concepts into comfortable, long-lasting
products.
The Challenge: Compact Devices, High Power Needs
Wearable electronics face a unique design dilemma. They require lightweight and ultra-compact power sources
while maintaining consistent output over extended usage. At the same time, users expect seamless functionality —
continuous connectivity, 24-hour heart monitoring and instant data synchronization — all without frequent
charging.
Traditional batteries simply can’t meet these expectations. That’s where PKNERGY’s lithium-ion and
lithium-polymer batteries make the difference. Our R&D team focuses on optimizing form factors, achieving
thin, flexible designs that integrate perfectly into wearable structures without compromising energy density.
Why Lithium Batteries Are Essential for Smart Wearables
Lithium-based batteries have become the dominant technology in the wearable segment for their superior
electrochemical properties:
- High Energy Density: Delivers long operating hours in very small enclosures.
- Lightweight Construction: Reduces total device mass for better comfort and portability.
- Fast Recharge Time: Enables users to quickly power up and stay connected.
- Stable Voltage Output: Ensures reliable sensor readings and wireless communication.
- Long Cycle Life: With 1000+ cycles at 80% DOD, our batteries last for years of daily use.
Combined with optimized BMS and protection circuits, PKNERGY’s wearable batteries support continuous use scenarios
with low heat generation — a critical safety factor for skin-contact devices.
