Presentation to International

Battery Seminar

AnteoTech Ltd (ASX: ADO) ("AnteoTech" or "the Company") provides the attached presentation, which is being presented by Mr Manuel Wieser, AnteoTech, Head of Energy, at the International Battery Seminar, in Orlando, Florida, on Thursday 31 March at 2.25 pm (Eastern Daylight Time).

The International Battery Seminar is an industry event bringing together leading OEM's and cell manufacturers, showcasing the state of the art of worldwide energy storage technology developments for consumer, automotive, military, and industrial applications.

AnteoTech's presentation titled "Binder Networking Made Easy: Drop-In Cross-Linker Additives for High Silicon Content Anodes" focuses on the Energy division's work in developing the cross-linker additive AnteoX™ for pairing with water-based binders. The presentation showcases the versatility of AnteoX as it is applied to various binder chemistries and the electrochemical test results, which form the culmination of the most recent work in the binder program. The data has, of necessity, been kept confidential and can now be made public.

Of particular note are the positive results obtained from in-house testing of cycling capacity retention when using AnteoX in a silicon-rich anode that delivers more than 1000mAh/g of anode coating capacity in a full cell battery. The inclusion of AnteoX in the binder formulation improves the cycle life of the battery by up to 100%, maintaining 70% capacity retention at 200 cycles.1

The presentation also highlights results recently received from Collaborator 8's testing, demonstrating AnteoX achieves a substantial improvement in mechanical strength when paired with a commercial PAA co-polymer binder product. The samples containing AnteoX showed an up to 56% increase in ultimate tensile strength when compared to a control, along with an increase in the elastic modulus of the binder. The increase in strength is evidence of the strong cross-linking effect facilitated by AnteoX and the increase in the elastic modulus of the binder material has been shown to be an important factor in managing the volume expansion of silicon-containing anodes, thereby improving their electrochemical performance and longevity.

The team is very encouraged by Collaborator 8's test results as they provide yet another technical proof point of AnteoX's benefit with the Collaborator's existing binder product. The results are planned to be communicated to Collaborator 8's customers, while AnteoTech will continue to work closely with Collaborator 8 to firm up a range of business opportunities.

In parallel, AnteoTech is targeting to replicate these results with other Collaborators in the binder space that offer different binder chemistries to the industry. Mr Wieser is being accompanied to the

conference by Ms Glenda McLoughlin, AnteoTech non-executive director and the newly appointed Chief Commercial Officer-Energy, Mr Conor Marley, to both support Manuel and familiarise themselves with the most recent industry developments.

Mr Marley joins AnteoTech's Energy division as an interim appointee coming from a long career in the energy sector which has included Global Vice President roles with Chevron covering Downstream Energy & Chemicals in sales and marketing and more recently Asia Pacific Sector Lead for Advisian (a division of Worley Parsons) having responsibility for the Downstream Energy and Chemicals business that delivered business improvement breakthroughs for their clients across the Asia Pacific.

This announcement has been authorised for release by the Board.
