Further Goliath Technical Milestone Achieved

 

D5 testing complete; safety characteristics confirmed to be superior to
lithium-ion equivalents

 

Ilika (AIM: IKA), an independent global expert in solid-state battery
technology, announces it has completed testing of its Goliath D5 prototypes,
thereby further confirming the safety characteristics of Ilika's batteries.

 

The testing reconfirmed the benefits of Goliath relative to lithium-ion
equivalent across a number of key variables - reinforcing the fact that
Ilika's cells have the potential to provide electric vehicles (EV) with
lighter, safer, cheaper batteries with longer ranges and faster charging
capabilities.

 

Further to the RNS Reach  dated 05 September 2024
https://tinyurl.com/xeydwhkp (https://tinyurl.com/xeydwhkp) , the completion
of the testing of the D5 prototypes is a key milestone, with the Company
focused on delivering on its minimum viable product (MVP) roadmap, which will
underpin licensing opportunities.

 

The D5 prototype is designed to build on the characteristics of the D4 data
point achieved in 2023. This was achieved by optimising the cell architecture
to increase Goliath's unique safety value proposition without compromising
cell energy density.  The key findings from the testing programme provide
further validation along the development curve to D8 and MVP samples during
calendar year 2025:

 

·    Exceptional results from the nail penetration test carried out by
University College London as part of the Faraday Institution funded Safebatt
Industrial Sprint programme.

o  The results classify puncturing the D5 prototypes as a EUCAR 3 hazard
event, with no leakage, no venting, no fire or flame, no rupture and no
explosion. In contrast, puncturing the benchmark lithium-ion battery resulted
in a higher EUCAR 6 event, i.e. a rupture accompanied by flying parts of the
active mass, fire and flame.

·    Components confirmed to be non-flammable by DEKRA, the world's
largest independent, non-listed expert organisation in testing, certification
and inspection.

·    Temperatures during failure approximately 300°C lower than
comparable Li-ion cells shown in Accelerated Rate Calorimetry testing carried
out as part the Industrial Sprint, by the University of Oxford.

·    Improved capacity at higher discharge rates.

o  D5 prototypes can be discharged at twice the rate of P1 prototypes without
impacting their capacity.

 

Improved safety performance of Goliath batteries relative to conventional
lithium ion means that EV designers can reduce the mechanical protection and
reinforcement that would otherwise be required to protect the battery pack. In
turn, this enables lighter and less expensive EV designs that have a longer
range for the same amount of energy. The D5 data point makes this improved
safety performance clear.

 

Ilika's CEO, Graeme Purdy, stated: "While our test programme will continue
throughout our journey to a minimum viable product, we're delighted with this
positive outcome. The validity of the results is enhanced by the independent
execution of the tests carried out by University College London and the
University of Oxford under the Faraday Institution's Safebatt Industrial
Sprint programme and by DEKRA.

 

"Meeting our D5 milestone pushes our technology further along the curve
towards D6, which is a data point for larger area 10Ah batteries, the results
of which we expect to announce in November 2024."

 

The Faraday Institution's CEO, Professor Martin Freer, stated:

"We congratulate Ilika on achieving this milestone on their roadmap to a
minimum viable product. The collaboration is a terrific example of the
transfer of knowhow from the Faraday Institution community - in this case at
UCL and the University of Oxford on the science of battery safety - to deliver
impact for a UK battery SME via the Industry Sprint programme."

About Ilika plc - https://www.ilika.com (https://www.ilika.com/)

Ilika specialises in the developing and commercialisation of solid-state
batteries. The Company's mission is to rapidly develop leading-edge
IP, manufacture and license solid state batteries for markets that cannot be
addressed with conventional batteries due to their safety, charge rates,
energy density and life limits. The Company achieves this by using
ceramic-based lithium-ion technology that is inherently safe in manufacture
and usage, higher thermal tolerance and easier to recycle which
differentiates our products from existing batteries.

 

The Company has two product lines. Its Stereax batteries which are designed
for powering miniature medical implants, industrial wireless sensors and
specialist internet of Things (IoT) applications and the Goliath large format
batteries designed for EV cars and cordless appliances.

 

About SafeBatt: https://www.safebatt.ac.uk (https://www.safebatt.ac.uk)

The Faraday Institution's (https://faraday.ac.uk/) SafeBatt project is a
collaboration, led by the University of Oxford, of seven universities (Oxford,
University College London, King's College London, Newcastle, Sheffield,
Warwick and Cambridge) as well as industrial partners, each bringing unique
capabilities to the investigation of the science of battery safety.
