Addionics has introduced a new low-temperature battery architecture designed to reduce the performance losses lithium-ion cells suffer in cold weather, a problem AAA independently measured this year at close to 40 percent of usable electric vehicle range. The Tel Aviv-based battery technology company is extending its existing Smart 3D Porous Current Collector platform, already backed by GM Ventures and Scania, into electric vehicles, trucks, defence drones and space applications.
How Addionics’ 3D current collector enables low-temperature performance
Addionics builds its architecture around Smart 3D Porous Current Collectors, which replace the flat metal foils used in conventional battery cells with an engineered three-dimensional porous structure. The porous design lets electrolyte and lithium ions move through the current collector plane rather than only around it, opening additional pathways through the electrode. According to the company, this shortens the distance ions must travel, improves access to active material and spreads electrochemical activity across a larger volume of the cell, which helps batteries retain more of their intended performance as temperatures fall.
Why cold-weather performance loss is a verified problem
The issue Addionics is targeting is well established independently of its own announcement. AAA’s May 2026 dynamometer testing found electric vehicles lost 39 percent of driving range and 35.6 percent of efficiency at 20°F compared with 75°F, figures close to the “up to an estimated 40%” range loss Addionics cites. Addionics says the same underlying physics constrains electric semi trucks, which risk reduced payload or route avoidance in winter, and defense drones, which can suffer shortened mission time and reduced operational radius in freezing conditions. In space applications, the company says reducing a battery’s heating requirement could deliver benefits across the solar array and launch mass as well as the cell itself.
What Addionics’ 3D current collector platform means for fleets and investors
The new application sits on top of a current collector platform that already has commercial and OEM backing rather than an unproven concept. Addionics closed a $39 million Series B round in 2024 co-led by GM Ventures and Deep Insight, with Scania participating, and the company operates what it describes as the first commercial-scale 3D current collector manufacturing facility. For procurement and fleet specialists, that existing manufacturing and investment base adds useful context alongside the low-temperature claims, which are newly announced and, as with most architecture launches at this stage, not yet backed by published independent performance data.
Addionics says the architecture is compatible with existing and emerging battery chemistries and does not require a change to cell chemistry to deliver its claimed gains. The company frames the announcement as one part of a broader push into always-on applications across automotive, defense, space and industrial robotics, suggesting further application-specific architectures are likely to follow as the underlying platform matures.
