Addionics has introduced a battery architecture designed to improve performance and charging at low temperatures, targeting electric vehicles, trucks, defense drones, and space and electric aviation. Based on its Smart 3D Porous Current Collectors, the technology reshapes ion transport inside the cell, aiming to reduce the performance losses batteries typically suffer in cold weather.
Addionics, based in Tel Aviv, Israel, has introduced a battery architecture aimed at improving battery operation and charging in low temperatures, targeting electric vehicles, trucks, defense drones, and space and electric aviation applications.
The company says conventional lithium-ion batteries lose usable energy in cold conditions while vehicles simultaneously draw more power for cabin and battery heating, which can cut an electric vehicle’s range by up to an estimated 40 per cent in severe winters. Addionics says electric semi-trucks are also affected, since a loaded truck already draws heavily on battery power at highway speed, and cold-weather losses could force route changes or reduced payloads. For defense drones, the company says freezing conditions can shorten mission time, cut operational radius, and reduce the power available for launch and maneuvering. Addionics adds that spacecraft face a related problem, since keeping batteries within their operating temperature range in cold conditions requires heater energy and thermal hardware that add to launch mass.
The new architecture is based on the company’s Smart 3D Porous Current Collectors, which replace flat metal foils inside the cell with a porous structure. Addionics says this creates additional pathways for electrolyte and lithium ions to move through the current collector plane, shortening transport distances and spreading electrochemical activity across a larger volume of the electrode. The company says this allows batteries to retain more of their performance as temperatures fall.
“By transforming the architecture of the battery cell, Addionics is removing some of the largest limitations that electrified systems have faced,” says Dr. Moshiel Biton, chief executive officer and founder of Addionics. “Batteries need to perform optimally in all locations and temperatures so that the products they power can be relied upon consistently.”
Biton adds: “We are enabling the always-on world to operate — all of the time, anywhere, even in the cold.”
Addionics says its current collector technology is compatible with existing and emerging battery chemistries and manufacturing processes, and the company works with companies across the defense, space, automotive and energy storage sectors.
