Solid-state battery technology company Ilika said it had significantly increased the volumetric energy density of a battery not much thicker than a postage stamp. The energy density was upped by a factor of three in the company's mm-scale StereaxO batteries by introducing wafer-thinning technology. The battery, code-named Golden Hind, was designed for miniature medical implants, which accounted for about 50% of the current commercial opportunities in Ilika's licensing pipeline. The cells were fabricated on standard semiconductor industry wafers using Ilika's vacuum deposition technique. 'This crucial manufacturing step will produce ultra-thin solid-state batteries about 250 um in thickness, which is not much thicker than a postage stamp,' the company said. Golden Hind prototypes were currently undergoing parallel evaluation at Ilika's facility to fully qualify the cells for a product launch in the second quarter of 2019. 'This is the latest improvement in the processing of miniature StereaxO cells,' chief executive Graeme Purdy said. 'We are integrating our unique approach to materials deposition with standard semiconductor manufacturing technology to deliver best in class solutions.'
