High Energy Density Miniature Solid-State Batteries
Ilika (AIM: IKA), a pioneer in solid-state battery technology,
announces that it has increased the energy density of its thin film
batteries by 10-fold since the launch of its first product, the
Stereax(R) M250, by improvements made in Ilika's processing
methods. This makes Stereax(R) the most competitive, energy dense
technology for miniature solid-state batteries used in IoT
(Industrial sensors, Automotive, Smart Homes and Cities) and
MedTech.
The launch, on 10(th) April 2019, of the Company's Stereax(R)
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(R) products. Photolithography is a widely
used microfabrication method in the semiconductor industry. It has
the advantage over contact masks of being able to optimise the
amount of battery active materials over the footprint and volume of
the batteries and minimise the proportion of inactive materials
such as contact pads. A second technical milestone has been the
deployment of wafer thinning, another widely used technique in the
semiconductor industry. With a current wafer thickness of 100
microns, this back-end processing technique now yields thin
solid-state batteries with a minimal amount of inactive yet
mechanically-neccesary wafer material, with the effect of
increasing the energy density of the battery. Finally, Ilika has
succesfully doubled the amount of cathode material per footprint,
in other words the electrical charge reservoir, without de-rating
the other battery specifications significantly.
All three technological milestones have led to a 10-fold
increase in the amount of energy capable of being stored in the
minimal volume of the Stereax(R) batteries. This progress is key to
the commercialisation of solid-state batteries in MedTech and IoT
markets where latest trends require, at the same time, less volume
(to enable increasingly smaller devices) but also more energy (to
yield more functionality, longer range communication protocols such
as LoRaWAN and NB-IoT, shorter recharging time and longer
life).
In the next three years, Ilika is planning to deploy other
technologies from the semicondutor industry, such as wafer stacking
and thinner wafer materials by targeting a further five-fold
increase, designed to yield higher energy density values, competing
favourably against coin cells or cylindrical batteries.
Graeme Purdy, CEO of Ilika, said: "The continuous development of
Ilika's solid-state battery technology and the deployment of
state-of-the-art techniques used in the semiconductor industry will
enable a larger range of MedTech and IoT applications to be powered
by solid-state batteries."
