The patented lithium-sulfur batteries of the Brno researcher Tomáš Kazda could be produced in Norway. The private company plans to build a battery factory there, including a prototype line, in the coming years.

Lithium-sulfur batteries represent an alternative to current lithium-ion (Li-ion) batteries and may mean a shift in electromobility, said Radana Koudelová, spokeswoman for the Brno University of Technology in a press release.

Two years ago, researcher Kazda from the Faculty of Electrical Engineering and Communication at BUT filed a European patent for the modification of lithium-sulfur battery cells, which, according to him, mean the future in electricity storage. The patented modification of the electrodes made it possible to maintain a similar number of charging cycles as is common with today’s available batteries, but with many times higher capacity.

A Norwegian partner, who wants to start building a factory next year, also took part in the research. The first part of the construction is to be completed in 2024. The main customers will be mainly European car manufacturers.
“Currently, more than 60 percent of Li-ion batteries produced go to the automotive industry, not only for electric cars but also for electric buses. The main customer is clearly transport. Electric trains are also being produced to allow the battery to travel in areas where the line is no longer electrified, “said Kazda.

In addition to conventional Li-ion batteries, the Norwegian manufacturer wants to gradually offer an alternative, so one of the modules of the planned factory should also include a production line for a new type of lithium-sulfur batteries.
