Battery Makers Pivot to Data Centers

🔑 Enhanced Key Takeaways

• •Ford plans to invest $2 billion over two years to repurpose its Glendale, Kentucky plant for 5+ MWh storage systems targeting data centers, with production starting in 2027.[1]
• •LG Energy Solution and SK On are repurposing EV battery lines for stationary storage, while GM partners with Redwood Energy to deploy new and used EV batteries in hybrid data center solutions.[1]
• •Converting EV battery plants to stationary storage costs up to one-third of total capex and takes up to 18 months, involving retooling for larger cells with thicker electrodes and grid-ready racks.[1]
• •Data centers use BESS for UPS, load buffering against AI-induced MW-scale power swings, faster grid interconnections, and demonstrating flexibility to utilities.[2]

🛠️ Technical Deep Dive

• •Shift from EV batteries prioritizing energy density to stationary storage emphasizing cycle life requires larger cells, thicker electrodes, different additives, and replacing pack assembly lines for bigger grid racks.[1]
• •Data center BESS roles include UPS (with VRLA-to-Li-ion transitions and long-duration needs), real-time load buffering for AI workloads, interconnection enablement, and grid flexibility; alternatives like sodium-ion, redox flow, nickel-zinc, and second-life EV batteries are under review.[2]
