While the innovation of the microchip, along with the wearables and IoT technology, has propelled the small electronics market by leaps and bounds, its associated battery innovation has remained sluggish. Today’s wearables demand longer device run time, rechargeability, and occasional peak power for their long-range communications, but the existing coin cells seldom pack all the requirements.

Millibatt, an innovative battery technology company, is rising above the conventions and changing the status quo with its revolutionary rechargeable, small sized coin cells, Nimbus. The Nimbus product line is the culmination of micro electromechanical systems (MEMS) principles applied to coin batteries, delivering a quantum leap in power density.

“Millibatt builds high-power, long lasting Nimbus batteries in millimeter formats and holds seven patents in its processing, packaging, and fabrication,” explains Janet Hur, co-founder and CEO of Millibatt.

The Nimbus product line consists of a series of rechargeable high-power coin cells, the most popular being the Nimbus 9 and Nimbus 20 series. While Nimbus 9 is a button cell in a nine-millimeter format perfect for Bluetooth devices and wearables, Nimbus 20 is a coin cell in a 20-millimeter format that is most suitable for high power applications like IoT and LoRa devices. Nimbus is currently used across all sectors, from consumer and medical space to smart factories and aerospace applications.

The Nimbus series’ notable applications are found in fitness bands, biomedical patches, personal asset trackers, remote sensors, and more. These batteries also support longer device runtime and reliable wireless connection, thanks to their high-power density.

Underpinning its excellence is the company’s elite team with a combined experience of 45 years in battery science, engineering, and micromachining to cater to bespoke battery requirements in terms of dimensions, shape, or chemistry.

For instance, Millibatt’s batteries are a clear step up from the traditional small format cells comprising a 2D planar structure—two flat discs simply sandwiched together with chemicals—to include an additional intricate 3D structure between the flat discs for increasing the internal surface area between the electrodes. This maximizes the ion exchange rate between the surfaces, giving rise to high power density. The upgrade from 2D to 3D structure augments the internal footprint to provide the batteries with added power boost—a core differentiator for Millibatt in the battery manufacturing space. Millibatt’s patented process allows this structure to be realized in previously unattainable formats.

Equally commendable is Millibatt’s client engagement approach, which starts by understanding a client’s intended application. Then, leveraging its expansive battery database from their R&D and matching it with the client’s precise requirements, the company customizes its standard battery modules in the appropriate shape and dimension. Finally, the team sends a set of customized battery samples to the client to support their product development.

Today, Millibatt is continuously expanding their coin cell product line, on top of already popular standard Nimbus 9 and 20, to meet the various demands in the electronics market. These competencies are making Millibatt a go-to battery supplier for the increasing demand for wearables and LoRa modules of varying shapes and sizes. Moving forward, with more significant upgrades to offer higher power rechargeable cells in customizable sizes, Millibatt is poised to move its innovation needle even further in the small electronics arena.
