Additive manufacturing is revolutionizing battery production by allowing energy storage to take any shape, potentially enabling lighter consumer electronics, longer-range drones, and more efficient electric vehicle manufacturing processes.

Key Points

• 3D printing allows batteries to be integrated into structural components like drone airframes or smartglass frames.
• The technology is chemistry-agnostic, meaning it can improve lithium-ion, sodium-ion, and solid-state battery designs.
• Silicon Valley startup Sakuu is developing a solvent-free printing process to eliminate energy-intensive drying ovens in assembly lines.
• Removing industrial ovens from manufacturing could significantly reduce production costs for electric vehicle batteries.
• Startups are currently prioritizing defense applications where initial cost and scale requirements are more flexible.

Why it Matters

This shift toward additive manufacturing could fundamentally lower the cost of electric vehicle production by streamlining assembly and reducing energy consumption. By enabling batteries to conform to any shape, the technology also paves the way for more compact, high-performance consumer devices and advanced robotics.
