Ilika Technologies Ltd was founded in 2004 as a spin-out from the School of Chemistry at the University of Southampton. The company quickly established an international reputation for the rapid development of novel materials and secured commercial partnerships with a portfolio of blue-chip companies including Asahi Kasei, Shell, Applied Materials, Toyota and Murata .

In 2014, Ilika started designing the Stereax family of mm-scale solid state batteries for medical implants and industrial IoT devices.

The Stereax M300 for medical implants is in its final stages of development and prototypes will shortly be available for evaluation.

In 2018 Ilika began developing its larger format Goliath solid state batteries designed for electric vehicles, with a three-stage scale-up plan from kWh through MWh and onto GWh.

The company’s growth has been financed by three rounds of venture capital, an initial public offering (IPO) on the London Stock Exchange in May 2010 and three placings in April 2012, July 2018 and March 2020.

In 2023 Ilika and Cirtec Medical signed a ten-year manufacturing licence to produce the Stereax range of mm-scale batteries at Cirtec's facility in Lowell, Massachusetts, US.
