Sodium-based batteries are emerging as a promising alternative to lithium-ion batteries, which face high costs and limited lithium supply. Sodium is more abundant; in the US alone, there are 23 billion tons of soda ash that could be used to produce sodium. Sodium batteries can be more cost-effective, perform better in cold weather, and may endure more charging and discharging cycles. While sodium-based batteries offer many advantages, one key area of improvement at room temperature is addressing dendrite formation, which can impact safety and performance. To overcome this problem, liquid sodium-potassium anodes have been proposed. However, there has not been a viable manufacturing process to fabricate liquid metal anodes. This BRITE Pivot award supports fundamental research aimed at developing a scalable manufacturing technology for liquid metal anodes in sodium batteries. If successful, it will pave the way for large-scale production of next-generation rechargeable batteries that are low-cost, high-capacity, and reliable—unlocking new economic opportunities in the advanced manufacturing sector. This award supports an integrated experimental and theoretical study to address key challenges in a new battery manufacturing process, including ion diffusion limitations, irregular electrodeposition fronts, and the precise control of multi-metal deposition ratios required to form desired liquid metal alloys. This new process involves complex electrochemical phenomena that are not
