Israeli battery developer Storedot announced a new cell design to more readily integrate extreme fast charging into EVs.
So-called I-Beam XFC cells are designed to be incorporated directly into the battery pack. Its 100in5 cell technology, which it claims enables charging 100 miles of range in five minutes. The company said while standard cell-to-pack architectures aim to improve range and energy density, Storedot is also focusing on extreme fast charging with its new concept.
It has done away with the module housing, terminal plates, side plates, internal connectors, battery management and complex cooling systems. It said the packaging space and overall weight can thus be reduced. As a result, CTP design significantly improves the weight, volume, and energy density of the battery pack, thereby enabling an increase in the range of the EV, it said.
“It leapfrogs the complexity and cost challenges of embedding XFC capability at the vehicle level, allowing EVs to be charged even more rapidly,” it said.
Structural cooling is embedded into the structure of each cell for enhanced thermal management. The company said this prevents localised hot spots and maintains uniform temperatures across the battery pack. That enables it to accept the ultra-high currents required for fast charging.
In 2024, Storedot anticipates milestones including plans to demonstrate the world’s first EV equipped with XFC technology and will begin shipping prismatic B-samples to OEMs. It will also expand operations in the US.
