Industrial BESS: duration and safety before density
Imagine an industrial plant that charges and discharges the same battery twice a day for fifteen years. That is thousands of cycles, one after the other, day and night. In such a scenario, the right question is not “how much energy goes into a metre...High-current batteries: how they handle real-world stress
Imagine a winter morning in Northern Italy. The system is covered in frost, the temperature is below zero and you need to charge the storage system quickly to make the most of the first few hours of sun. It is precisely in moments like this that you realise whether a battery is...Battery safety: what happens when they heat up
Imagine a BESS container installed in an industrial area, next to a warehouse where dozens of people work every day. Inside, there are hundreds of cells storing energy. Under normal conditions, everything runs smoothly. But what happens if a cell...
Polyanionic cells: chemistry designed to last
If you've ever wondered what truly determines a battery's lifespan, polyanionic cells are one of the most interesting answers to have emerged in recent years. They are a family of chemistries, often sodium-ion based, designed precisely for longevity: thousands of...
Battery cycle life: why it matters more than kWh
Let's do a quick quiz. You have two batteries in front of you, both 10 kWh, the same size, similar price. The first states about 3,000 cycles, the second many thousands. Which one is more worthwhile? If you answered “it depends”, you're on the right track. Because the...

New 280Ah salt battery cells available
In cooperation with our technical partner, Heiwit has new sodium-ion cells with the highest density in the industry - 28Ah - already available for marketing. These make our batteries extremely efficient, allowing them to be recharged...
Sodium-ion or lithium-ion batteries?
Storage batteries are used with solar panels to store the energy produced during daylight hours. This allows the stored energy to be used during the night or at times when the panels are not producing enough...
Sodium ion batteries: what they are and their use as storage for photovoltaic systems
Photovoltaic panels convert sunlight into clean electricity, powering our homes and businesses and reducing dependence on fossil fuels. However, to make full use of this renewable energy, a storage system is needed...
Green transition of the energy sector: becoming a prosumer without owning a photovoltaic system
The transition to a green energy system is now an urgent necessity. In order to achieve this, it is crucial to incentivise the production of energy from renewable sources. Alongside the installation of photovoltaic systems on roofs, in recent years...
