At a time when the demand for battery power storage is growing, pv journal spoke to Eloisa de Castro, CEO of Enerpoly, a Swedish firm that’s making ready to launch the world’s first zinc-ion battery megafactory on its house turf. Rechargeability points resolved, the corporate expects secure and sustainable zinc-ion batteries, which rely solely on a European provide chain, to extend their market share within the coming years.

The power storage market is value between $44 billion and $55 billion in 2023, and it’s predicted to succeed in as much as $150 billion in 2030. However, it faces main financial and provide challenges associated to using batteries product of scarce and simply priced supplies. . How can your organization assist clear up these points?
Eloisa de Castro: Enerpoly develops and manufactures batteries utilizing zinc and manganese as energetic supplies. The strategic use of worldwide accessible and reusable supplies performs an essential function in guaranteeing a robust and dependable provide chain that may stand up to worth volatility and geographic constraints. Our zinc-ion batteries rely 100% on a European provide chain, which reinforces their sturdiness.
Our batteries are environmentally pleasant, cost-effective, and secure, and tackle a wide range of power station storage necessities, together with grid stabilization companies or dependable backup energy. Essentially, the traits of our batteries enable us to supply scalable, dependable and sustainable power storage options.
Enerpoly’s know-how meets the affordability, security, and sustainability calls for needed for a clear power transition. In addition, our current grant from the Swedish Energy Agency, which will probably be used to construct the world’s first megafactory for zinc-ion batteries, exhibits that zinc-ion batteries may be low cost and mass-produced in measure.
How do you clear up the rechargeability points widespread to zinc-ion batteries?
Enerpoly has carried out a number of key improvements to handle these points. Our zinc-ion batteries use a zinc metallic anode and a manganese dioxide cathode. We have developed methods that restrict inactive manganese species from forming. This is essential as a result of manganese oxide can change part to electrochemically inactive Mn3O4 and may trigger battery injury. This innovation considerably improves battery efficiency and rechargeability.
Second, we now have to cope with the issue of zinc dendrite formation on the anode. Zinc dendrites may cause short-circuits. We developed a proprietary electrolyte and a managed battery operation technique to forestall dendrites. Optimizing the battery as a complete must be thought-about each time there’s a change in a part, and we’re cautious to steadiness any potential facet reactions which will happen in every bag. change.
What does the rise of zinc-ion batteries imply for the provision chain and zinc costs?
Zinc is already utilized in a wide range of industrial functions, so a rise in demand for zinc batteries is unlikely to end in massive worth fluctuations. Zinc-ion batteries are higher insulated from the provision chain and inflation points which have affected the power area in recent times. If you take a look at zinc costs versus lithium costs in 2022 and 2023 when commodity costs are essentially the most risky, lithium has 14x worth volatility and zinc has virtually 1x.
In addition to that, I count on that the present recycling of zinc and the extraction of zinc from different essential industrial functions will create a extra round provide chain and make sourcing versatile, thus preserving the worth low and steady. on. Enerpoly’s give attention to zinc, a extra steady and fewer geopolitically constrained materials, positions us to correctly handle any potential value instability regardless of rising demand.
How worthwhile is zinc mining and refining?
Here’s what zinc is in favor of: zinc is responsibly and sustainably mined in Europe, and there may be 200 instances extra mining capability for zinc than for lithium in Europe. As for refined battery-grade supplies, Enerpoly makes use of related supplies as non-rechargeable zinc-alkaline batteries, and the refining and manufacturing of zinc for battery manufacturing in Europe has been profitable and dependable for many years suppliers of the present European battery giants. for the non-rechargeable model of this battery. I am unable to say for certain that we are going to by no means run into points, however I’ve confidence that the prospect of operating into main obstacles could be very low.
Aside from provide chain points, lithium-ion batteries additionally carry important security dangers and face challenges in sustaining their manufacturing and recycling processes. How are zinc-ion batteries completely different?
Enerpoly’s zinc-ion batteries include no elements that may trigger thermal runaway, and our zinc-ion batteries, not like different battery chemical substances, are usually not categorized as hazardous supplies and are subsequently secure. for transportation and storage. Some potential optimistic results of elevated security embody additional value discount as there is no such thing as a want for particular fireplace suppression elements and decrease insurance coverage prices, and the power to deploy in safety-critical functions in addition to dense city areas with out the chance of explosions.
Enerpoly batteries additionally use state-of-the-art dry electrode manufacturing and they don’t require dry rooms or poisonous manufacturing solvents, all of which scale back power consumption of their manufacturing. Because our batteries use related supplies to the well-established zinc alkaline non-rechargeable battery, there may be already an current recycling infrastructure accessible for recycling worldwide, which additional contributes to a decarbonized financial system and curiously, probably making batteries simpler because of the low value of decommissioning batteries which have fulfilled their lifetime.
