Northvolt has revealed that it has reached a new milestone in its sodium-ion battery research. The Swedish firm can’t yet put them in electric cars, but it’s getting closer.
Currently, battery materials are one of the biggest obstacles for the electric car. Very often, the presence of cobalt and lithium prevents us from seeing the environmental progress that electric cars bring to the automobile market.
But thanks to Northvolt, a big step could be taken in this direction soon. The Swedish consortium is moving forward with its projects. We suspect that the fundraising of more than a billion euros this summer will continue to bear fruit.
Thanks to its work, the company reveals that it has developed a sodium-ion battery. This does not yet have the capacity to be installed in an electric car. But its energy density of 160 Wh/kg allows it to store renewable energies, for example. In comparison, Tesla’s 4680 cells offer a density of 296 Wh/kg.
“The world has placed great hopes on the sodium-ion battery. I am very pleased to say that we have developed a technology that will enable its large-scale deployment to accelerate the energy transition”said Peter Carlsson, CEO of Northvolt.
“This is an important milestone for Northvolt’s market proposition. But such battery technology is also crucial to meeting global sustainability goals. This will make electrification more cost-effective, more sustainable and more accessible worldwide.”
Unbeatable costs for electric cars?
Although the density of these batteries is not yet at the level of lithium-ion, it is an upcoming objective of Northvolt. With these materials, storage is more efficient in the long term in batteries. Additionally, the cost is expected to be much lower than existing battery chemistries.
“Our sodium-ion technology offers the performance required to enable longer-lasting energy storage than alternative batteries.”
Carlsson also highlights “lower cost, thereby opening new avenues for the deployment of renewable energy production. The potential of sodium-ion technology in this market alone will have a considerable impact on the electrification of the planet.”
