Sila's specialty cells risk conflict with Panasonic

Sila is moving downstream because premium battery buyers often want a ready to qualify cell, not a materials science project. In drones, defense, AR/VR, and aerospace, smaller customers may not have the volume to convince a big cell maker to customize a design around a new anode, so a specialty cell line lets Sila sell a finished part instead of waiting for partners to integrate Titan Silicon into their own cells.1 2 3

• This creates channel conflict with Panasonic. Panasonic signed to buy Sila silicon anode material for EV batteries from Sila’s Moses Lake plant, so if Sila also sells finished cells, it shifts from supplier to partial competitor for some battery programs and customer relationships.1 5
• The pressure is real because rivals already sell complete cells. Amprius announced a 500 Wh/kg SiCore aviation cell for Q4 2026 and says it can scale through contract manufacturers. Enovix has reported commercial production of a silicon anode smart eyewear battery and is pushing drone cells toward higher energy density.2 6 7
• Selling cells also changes where margin is captured. A materials supplier gets paid for powder shipped to a cell factory. A cell maker gets paid for the qualified battery pack ingredient the drone or device company actually buys, which is why specialty cells can be attractive in fragmented niche markets.3

The likely direction is a split model, with Sila staying a materials vendor for high volume automotive programs while using specialty cells to win smaller, faster moving segments that need custom performance now. If that works, Sila can use finished cells as a wedge, then feed more of its anode material into broader manufacturing partnerships over time.1 3 5
