Enerpoly Developing Battery Storage of the Future

Enerpoly primarily develops batteries for stationary energy storage, and the potential applications include data centres and other types of properties, as well as households, holiday homes, and other buildings that need power sources.

- We are currently in the test phase and have built a pilot line where we test and develop the batteries for commercialisation,” says Samer Nameer, Co-founder and Sustainability Manager of Enerpoly. 

He explains the technology:

- The advantage of our technology relates to the stabilisation of the electricity grid in the event of capacity shortages or similar. Commercial properties can use the batteries as energy storage or as a service to tenants. We see opportunities for Enerpoly to put a whole new industry on the map together with other operators in the battery industry. There is great interest across Europe in stationary energy storage. 

As part of the Green Transition Leap initiative and together with experts from RISE, Enerpoly will receive initial support including consultations and workshops in battery systems.

- We are helping Enerpoly with material development and process development, says Maciej Wysocki, acting Head of the Production and Calculation unit. Furthermore, we will discuss market introduction and battery performance where we look at metrics to compare Enerpoly’s product with the lithium market. In the next step, we will jointly look at certification and accreditation of the company and its products, which is crucial for a successful market introduction. These are things, among others, that we are experts in at RISE.  

According to Wysocki, who has a central role in the business development of batteries at RISE:

- Enerpoly is one of several exciting Swedish companies showing a great deal of promise in terms of battery development. Many are talking about Northvolt as a crucial player in the Swedish battery ecosystem, but they also seem to forget that an interesting industry is emerging on the side that is putting Sweden on the map in battery development. Stationary energy storage will be crucial for coping with the sustainable transition going forward.

The company originated from the doctoral work that Mylad Chamoun did at Stockholm University. Samer Nameer explains:

- He researched batteries and recognised exciting things about the type of chemistry we work with today. Zinc-ion batteries have traditionally had a limited capacity, since the batteries are recycled after use. What we have managed to achieve is greatly increased service life and improved performance for that type of battery by further developing the chemistry and the other details in the batteries.

Highly increased service life and capacity

Nameer explains the technology and benefits:

- In our tests, the technology has achieved up to 2,000 charging cycles. This can be compared to traditional zinc-ion batteries, which normally have around 50 cycles. Other benefits are that the batteries are safe when we use water-based electrolytes. In addition, the raw materials zinc and manganese are cost-effective and available worldwide. This will be extremely useful as part of the sustainable transition. Moreover, the entire recycling infrastructure for our type of batteries is already in place through standard AA and AAA batteries.

Sweden new hub for global battery development

Enerpoly is part of the Swedish battery industry emerging from all directions. Nameer sees that the company has a clear position in the future and that Sweden can become a natural hub for global battery development:

- Our ambition is to start locally and sell in Europe through pilot projects, and then expand to the whole world. We have challenges to overcome before we can commence with sales, but we envision an entire industry in Sweden based on this type of chemistry that we work with. We see many companies investing in battery development, and all are needed to succeed in the transition.
