Core offering

Ensurge Micropower manufactures and sells ultra-thin, flexible solid-state lithium microbatteries (1–100 mAh range) featuring non-flammable solid electrolytes and a proprietary anode-less architecture. Products are designed for integration into hearables, wearables, medical devices, and industrial IoT applications, supported by a Microbattery Product Platform (MPP) that enables a path from prototype to volume production using roll-to-roll and precision stacking manufacturing techniques.

Product overview

Ensurge Micropower offers solid-state lithium microbatteries as its core product, complemented by the Microbattery Product Platform (MPP) which provides the scalable manufacturing infrastructure. The product portfolio centers on ultra-thin, flexible solid-state batteries for the 1–100 mAh range, serving hearables, wearables, medical devices, and industrial IoT sectors. The company has evolved from its origins as Thin Film Electronics ASA, pivoting from polymer memory to solid-state lithium battery technology, and rebranded to Ensurge Micropower to reflect its focus on advanced microbattery solutions.
