Sintesi del contesto e degli obiettivi generali del progetto

EASYLZINC’s patented technology provides green processes to locally produce critical powder materials used in zinc-based batteries. We
use a mechanical process to create Calcium Zincate powder (active material that can store electricity), with only water as solvent, and
have the know-how for the green production of Titanium Nitride (essential conductive additive). These innovations are combined to
produce 3 ready-to-use composite powders - Zincatin (ZnNi batteries), Zincatair (Zn-Air batteries) & Zincatem (Zn-MnO2 batteries).
EASYL’s production processes for these powder materials and composite powders will be licensed to industrial powder producers and
battery manufacturers, respectively. Our current technology has been tested with our team specialized in prototype cells & allows for the
production of batteries with a capacity of 1000 charge/discharge cycles while retaining 70% of the cell’s capacity.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

The Calcium Zincate has been extensively studied and presented here as it is the main product to be synthesized. It may correspond to 80-90% of the overall future production volume. Indeed, due to its zinc content, it participates to the energy storage capacity of the battery. Calcium Zincate main advantage is to avoid the displacement of zinc ions once the battery is discharges. It fixes the zinc atoms in a solid crystal that is non-soluble in the electrolyte, and hence, limits the zinc accumulation. The ageing studies have shown a good stability in time of dry powders correctly packaged, i.e. prevented from contact with air. The industrial production route envisioned by EasylZinc is based on a beads milling process that has been patented by the Company. A Pilot Production Line is under construction at the end of 2023. It should start by mid of 2024 with a production capacity of 150-200 kg/day.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

The study of calcium zincate reveals a significant potential for industrial application due to its advantage of not undergoing carbonation, unlike lime which is associated with quality issues and unpredictable results in electrochemistry. This characteristic of calcium zincate could lead to more reliable and higher quality outcomes in processes where electrochemical stability is crucial. The non-carbonation property suggests it could enhance the durability and efficiency of materials and systems in various industrial contexts, potentially revolutionizing aspects of production and material science.
