Sakuu has successfully produced a 0.5Ah lithium-ion battery cell using 100% dry-printed anode and cathode electrodes at a research facility in Silicon Valley. This development marks a shift in how energy storage components are manufactured, potentially increasing battery efficiency for future electric vehicles.
Why it matters
The use of dry-printing and integrated carbon fibre veils aims to enhance the structural integrity and electrical performance of batteries. This architecture helps dissipate energy slowly, which is a critical safety upgrade for the high-capacity power systems used in modern households and vehicles.
The new 0.5Ah test cell is constructed with 100% dry-printed electrodes, a significant departure from traditional wet-chemical manufacturing processes. This prototype was developed at a research facility in Silicon Valley to prove the viability of the Kavian platform.
The players

The details
The Kavian platform uses dry-printing to create electrodes and current collectors, eliminating the need for traditional solvents. To prevent the thin polymer films from wrinkling, engineers embedded carbon fibre veils directly into the current collector and dry-powder electrodes. This reinforcement maintains consistent electrical contact, while a series-connected PCC architecture allows energy to dissipate without generating excessive heat.

The Home Front
This development follows the industry-wide trend of replacing wet-chemical battery production with dry-printing to reduce costs and environmental impact. Sakuu's Kavian platform is currently a finalist for The Battery Awards, positioning this technology as a leader in the race to improve energy storage.
While this battery cell is currently in the research phase, homeowners interested in electric vehicles should watch for how dry-printed technology influences future EV range and safety. As these manufacturing methods scale, anticipate more durable and efficient energy storage systems in the next generation of home-linked electronics.
The takeaway
This breakthrough in dry-printed electrodes highlights a move toward safer and more reliable battery architectures. Stay informed on vehicle battery life specs as these technologies transition from research facilities like the one in Silicon Valley to the commercial market.
