Enerpoly manufactures low-cost, low-maintenance zinc-ion battery storage programs 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, below an EU-funded collaborative mission with Austrian startup EET.
Enerpoly has developed configurable, modular zinc-ion batteries for stationary storage functions. They’re appropriate for brief to medium period storage functions 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 know-how makes use of zinc steel 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 know-how is safer, with no chance of thermal runaway. The Swedish startup says it has handed all security requirements and says it has examined its batteries towards the UL 9540A commonplace.
Right this moment, Enerpoly is collaborating with the Austrian PV startup EET (Environment friendly Power Expertise) on the “ZincMate” mission. It’s mentioned that their purpose is to “drive the event and commercialization of an vitality storage gadget that may be put in in all European households.”
The mission companions obtained €870,000 ($937,000) in grant funding below the Eurostars-3 program, which comes from Vinnova and the Austrian Analysis Promotion Company (FFG). The overall price range of the mission 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 know-how, mixed with Enerpoly’s cost-effective batteries. EET creates photovoltaic programs 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 claimed 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 gadget is an built-in and patented measurement know-how that may assess a house’s vitality wants by means of a connection to {an electrical} outlet. This eliminates the necessity for extra set up or connection to a house’s electrical grid.
“At present, EET’s SolMate gadget is supplied with a state-of-the-art lithium-ion battery and it’s clear that battery know-how wants to enhance,” mentioned Christoph Grimmer, CEO of EET. “Transferring zinc-ion know-how for residential functions is the following step in the fitting route.”
The batteries developed below the ZincMate partnership will likely be examined in laboratory and residential environments, together with residences, small houses, and shared housing. The mission will begin this 12 months and run for 2 years.
