Sub-device integrated with Main device of the flow battery (A) and a cross-section of the sub-device (B)
Increasing Durability of Flow Batteries

LLNL researchers has developed an approach to mitigate HER on the ‘plating’ electrode, which uses a sub-device as a rebalancing cell to restore electrolyte properties, including pH, conductivity, and capacity across the main device of the flow battery.  This sub-device, which may need to be powered externally, has three major physical components: (1) a cathode electrode, (2) an anode…

Electrodeposition of Zn onto 3D printed copper nanowire (CuNW)
Direct Ink Writing of Hierarchical Zn Foam Electrodes for Energy Storage Applications

Improving the active material of the Zn anode is critical to improving the practicality of Zn-MnO2 battery technology. LLNL researchers have developed a new category of 3D structured Zn anode using a direct-ink writing (DIW) printing process to create innovative hierarchical architectures.  The DIW ink, which is a gel-based mixture composed of zinc metal powder and organic binders, is…

Compared with conventional slurry-based film electrode manufacturing methods, dry laser powder bed fusion is promising in generating structured electrodes for high power, low cost lithium ion batteries
Advanced Battery Manufacturing Technologies

To address many of the aforementioned challenges of manufacturing LIBs and SSBs, LLNL researchers have developed a number of inventions that offer proposed solutions for their components:
