French startup InjectPower is looking to set up a fab to build solid state batteries for medical applications.
The company has developed a miniature solid state lithium
ion battery technology that can be used in implanted devices. The battery cells
are 0.1mm thick with a footprint of 1mm2. The key is that the batteries can be
built on a 200mm wafer process with deposition, etch and passivation, and the company
is currently looking for a site for a cleanroom to be up and running in 2026.
The prototype devices have been made on the 200mm pilot line at CEA-Leti in Grenoble, showing an energy density of 250Wh/l. This currently has a yield of 50%, although the new cleanroom would see the yield increasing to 80- to 90%. A single 200mm wafer would produce 10,000 of the batteries, so a few hundred wafers would supply the predicted demand.
As a result the company has worked with US startup InjectSense
which has developed a MEMEs pressure sensor, controller ASIC and wireless
charging chip. These would be combined with the batteries for long-term monitoring
of intra-ocular pressure (IOP) in the eyeball. This assesses the effectiveness
of glaucoma treatments.
