**[Ilika plc](https://www.directorstalkinterviews.com/company/ilika-plc/ika.l)**(
[LON: IKA](https://www.directorstalkinterviews.com/company/ilika-plc/ika.l)), a 
pioneer in solid-state battery technology, has announced today that it has developed
processing methods to enable rapid customisation of its Stereax thin film cells 
to match customers’ requirements for form, fit and function.

The launch on 10th April 2019 of its Stereax® M50 mm-scale solid state batteries
for MedTech was a defining step for Ilika’s first product made using photolithography.
This marked a move away from the use of contact masks, which were deployed to produce
earlier Stereax products. Photolithography is a widely used microfabrication method
in the semiconductor industry. It has the advantage over contact masks of being 
able to create smaller feature sizes, of less than a micron. The technique is therefore
particularly suitable for forming Ilika’s mm-scale range of Medtech batteries. In
addition, the lead time for creating new wafer layouts is significantly reduced,
by up to 85%, making it possible to respond to customers’ requirements in an accelerated
manner. Also, the operating costs of using a photolithographic process rather than
contact masks are significantly less, in part due to the ability of photolithography
to enable a tighter spacing of devices on wafers, increasing wafer yield.

Examples of MedTech devices which can benefit from Stereax battery technology are
insulin pumps, cardiac devices, blood pressure monitors, neurostimulators, gastric
stimulators, smart contact lenses and smart dental braces.

Relative to standard lithium ion batteries, Stereax solid state batteries are safer,
have longer life spans of up to 10 years and lower leakage currents, making them
suitable for low power wireless charging.
