2. Ilika History
Page 2
Our mission is to rapidly develop leading-edge IP,
manufacture and sell solid state batteries (SSB)
for high performance applications. We will
achieve this using ceramic-based lithium-ion
technology that is inherently safe in manufacture
and usage.
15 years in rapid materials innovation
Founded 2004, AIM Listed 2010
Launched cm-scale SSB technology 2016 & mm-scale 2019
Collaborating with Auto industry partners & UK Government to
develop solid state EV pouch cells (2-year funded R&D program)

Calibration wafers with sensors, inserted in Si growth
chamber to ensure correct parameters for deposition
Logs deposition data in memory, or transmitted via RF
Cannot be cabled
Battery requirements met by Stereax SSB

Energy from vibrating blade is stored in
SSB
Data transmitted wirelessly to Cloud via Gateway (LoRa)
Recommended Stereax battery: C1000 (1 mAh)
Battery powers transducer which measures
vibration spectrum of blade as a “signature”
of its health (cracks, delamination, rain,
thunder…)
