Standard Prototypes

Evaluation Package

Discover the Stereax solid state battery technology by evaluating our standard prototype, the Stereax M250. We are currently making our standard solid state battery Stereax M250, available for evaluation to companies wanting to understand how solid state batteries can enable their prototype circuits and devices.

After evaluation we’re offering a free swap of the new Stereax M300 which will be available later this year. Don’t miss out on this offer – contact us now at info@ilika.com

Combine like "lego-blocks" to increase energy to mAh level

The ultra-thin, cm scale SSB 250µAh, Stereax M250 contains no liquid or polymer components and has no free lithium, either in the charged or discharged state, making it moisture resistant and appropriate for medical applications. Its low self-discharge allows it to be trickle-charged by an energy harvesting source such as vibration or a PV panel. Its high peak current enables the transmission of data using protocols such as Bluetooth Low Energy. The combination of energy harvester, transmitter, sensor and the M250, is ideal for integration into small, “fit and forget” autonomous sensor devices with multiple applications. If volume allows, use several Stereax M250 can be stacked to increase energy for your requirements, and customised in shape and form. This includes medical devices, the Internet of things (IoT) and sensors for smart homes, smart cities and vehicles. The M250 is provided on a rigid substrate (650µm).

STEREAX M300

We're also developing the Stereax M300 designed to address the needs of next-generation medical implants. The Stereax M300 is a miniature stacked battery of capacity 300 µAh and dimensions 5.6 mm x 3.6 mm x 0.9 mm. Like the M250 it can be customised to your specific requirements. The M300 is currently in its final phase of development and prototypes will be ready for evaluation Q4 2021.
