Ilika charges higher after achieving record battery energy density

Ilika jumped on Tuesday after it achieved its highest ever volumetric energy density of its ultra-thin solid-state batteries.

The AIM-traded company's mm-scale battery, codenamed Golden Hind, increased the volumetric energy density threefold by introducing wafer-thinning technology into its manufacturing workflow to produce ultra-thin solid-state batteries about 250 um in thickness, not much thicker than a postage stamp.

The battery is specifically designed for miniature medical implants, which account for approximately 50% of opportunities in the Ilika's licensing pipeline, and are fabricated on standard semiconductor industry wafers using a vacuum deposition technique.

The cells can be manufactured at Ilika's pilot line in Southampton after the development of materials and process technologies to align with customer demands.

Graeme Purdy, chief executive of Ilika, said: "This is the latest improvement in the processing of miniature Stereax cells. We are integrating our unique approach to materials deposition with standard semiconductor manufacturing technology to deliver best in class solutions."

Ilika's shares were up 12.96% at 30.50p at 1004 GMT.
