It appears to me unsold that more material is required for bigger tests, going by this in the announcement.

"To meet the requirements for stage 2 of the project, the Company has ordered a 55L reactor to increase production capacity by 25 times. The new equipment will enable the production of at least 250kgs of anode material per year, which will be more than sufficient to facilitate the increased demand from Leclanché as it continues to test the material in its battery manufacturing plant."
