Enerpoly manufactures low-cost, low-maintenance zinc-ion battery storage methods for 2 to 10 hours. The Swedish battery specialist now plans to develop prototypes of a residential plug-in storage system with rechargeable zinc batteries in Europe, beneath an EU-funded collaborative undertaking with Austrian startup EET.
Enerpoly has developed configurable, modular zinc-ion batteries for stationary storage purposes. They’re appropriate for brief to medium length storage purposes of two to 10 hours.
Its 3 kWh battery packs weigh 60 kilograms and measure 800 mm x 177 mm x 432 mm. They function at a temperature of -10 C to 50 C. The nominal voltage stands at 48 V, with a nominal capability of 60 Ah. The battery packs have a most cost/discharge energy of two.8 kW, with 1.4 kW of steady energy.
Enerpoly’s expertise makes use of zinc metallic because the anode and manganese dioxide because the cathode, with a water-based electrolyte. Its proprietary battery cells are constructed with a prismatic kind issue.
It claims that the expertise is safer, with no chance of thermal runaway. The Swedish startup says it has handed all security requirements and says it assessments its batteries towards the UL 9540A normal.
Immediately, Enerpoly is collaborating with the Austrian PV startup EET (Environment friendly Vitality Expertise) on the “ZincMate” undertaking. It’s mentioned that their purpose is to “drive the event and commercialization of an vitality storage system that may be put in in all European households.”
The undertaking companions acquired €870,000 ($937,000) in grant funding beneath the Eurostars-3 program, which comes from Vinnova and the Austrian Analysis Promotion Company (FFG). The full finances of the undertaking is €1.74 million.
The businesses will develop ZincMate prototypes of a plug-in storage system with rechargeable zinc batteries. The technical foundation for ZincMate is EET’s on-grid expertise, mixed with Enerpoly’s cost-effective batteries. EET creates photovoltaic methods with vitality storage that may be positioned on a balcony and plugged right into a wall outlet, in order that householders and tenants can generate their very own renewable electrical energy.
EET, based in 2017, is alleged to be the one firm that produces storage gadgets that may be put in by amateurs, with out the assistance of technicians. The core of EET’s innovation for the SolMate system is an built-in and patented measurement expertise that may assess a house’s vitality wants by a connection to {an electrical} outlet. This eliminates the necessity for added set up or connection to a house’s electrical grid.
“At present, EET’s SolMate system is supplied with a state-of-the-art lithium-ion battery and it’s clear that battery expertise wants to enhance,” mentioned Christoph Grimmer, CEO of EET. “Transferring zinc-ion expertise for residential purposes is the following step in the appropriate course.”
The batteries developed beneath the ZincMate partnership will probably be examined in laboratory and residential environments, together with residences, small houses, and shared housing. The undertaking will begin this yr and run for 2 years.
