Wearable Flexible Battery.

Innovate. Challenge. Connect.

wearable flexible battery

Lionrock Batteries was founded in 2017 with mission to develop wearable flexible batteries. The founders are innovators with a passion to supply batteries that are ultra-thin, bendable, flexible and rechargeable battery — wearable flexible battery to world with rising wearable and IoT needs.

Prior to Lionrock, the founders had launched crowdfunding projects developing functional watch straps. They saw the constraints on wearable devices because of conventional batteries: wearable devices with communication, activity tracking, biometrics and health monitoring functions are all power demanding. However, rigid conventional batteries would limit wearables to bulky design, hinder wearables from being smarter, lighter or more comfortable. Hence the founders determined to setup the company to develop wearable flexible battery.

The rise of IoT, wearables, health monitors, and environmental sensors are in huge demands. The industry is expecting rising need of wearable flexible battery (Report from IDTechEx). We aim to meet this demand with our game-changing wearable flexible battery technology, taking flexible battery and the connected devices market to a whole new level.

Wearable Flexible Battery Application Scenarios

Functional In-Sole

A thin and flat wearable flexible battery can well fit into an in-sole to power electronics and sensors of all kinds.

Medical Patches

There are a many biometric tracking patches being developed. In many cases, users have to wear the patch for 24 hours.  The industry is expecting application of wearable flexible battery instead conventional rigid and bulky battery on skin patches. (More on Newswire)

Watch Strap

If a watch strap has wearable flexible battery inside, its power capacity is roughly equivalent to battery stored inside a smart watch.  Hence with wearable flexible batteries, smart watch can extend its operating hours, support more complicated functions, and reduce the size of the watch case.

Pet Collar

There are many pet trackers today. Nearly all of them are in a form of dongle adhere to the pet collar. If wearable flexible battery is used, then the pet collar by itself is already a functional device with power inside.

C.C. Poon

Engineering, Co-Founder

C.C. earned his B.Eng at Imperial College, London and M.S. at Rensselaer Polytechnic Institute, New York. In 1992, C.C. started as an IC designer at Motorola (US and HK). In 2002, he founded Acelab Technology Ltd. (HK), focusing on design, manufacturing and installation services of LED and related technologies. He designed and installed the first LED rooftop signage at the HK International Airport, as well as the first LED emergency signage system for HK Mass Transit Railway (MTR). As part of a proof-of-concept, C.C. also designed and built a smartstrap with GPS for Pebble (now Fitbit).
