Sakuu has successfully produced a 0.5Ah lithium-ion battery cell using 100% dry-printed anode and cathode electrodes at its Silicon Valley research facility. This achievement marks a significant development in the application of dry-printing techniques for battery production.
Why it matters
By eliminating wet manufacturing steps, Sakuu aims to improve safety and production efficiency through its PCC architecture. This method allows energy to dissipate slowly, reducing the risk of excessive heat generation during battery operation.
The test cell utilizes a 0.5Ah capacity and features electrodes that are 100% dry-printed. The architecture also incorporates a carbon fibre veil to enhance conductivity and structural integrity.
The players
Sakuu
