Breakthrough battery technology

We are developing revolutionary new batteries using novel sodium-based chemistries to power the future green economy.

We have already made high performance lab samples and are now commercializing the technology for next generation electric vehicles, portable electronics, starters and grid energy storage.

In recognition of our breakthroughs, BroadBit won the first EU Innovation Radar prize.


Ultra-high energy density batteries

Twice the energy density of the current Li-ion technology


Double the range at same weight.

Ultra-fast charging batteries

Five times the charging rate of the current Li-ion technology


Full recharging in five minutes.



Our batteries enable double an electric vehicle's range.

We eliminate range anxiety and make zero emission vehicles competitive in price and convinience with internal combustion vehicles.

Engine Starters

We increase the lifetime and durability or starter batteries.

We eliminate dead batteries due to cold conditions and destroyed batteries due to over discharging.

Portable electronics

Our batteries allow your phone and tablet to last twice as long between charges.

Or they can be recharged in just a few minutes.

Grid storage

We enable competitively priced renewable energy storage increasing grid stability with intermittent power.

The abundant raw materials for our sodium-batteries will not run out even in huge production.
