Seeo Inc., established in 2007, specialized in developing advanced rechargeable lithium-ion batteries. The company’s foundation stems from innovative technology initially created at Lawrence Berkeley National Laboratory through the U.S. Department of Energy’s Batteries for Advanced Transportation Technology program. Seeo’s primary achievement was the creation of nanostructured polymer electrolytes, which significantly improved battery safety and performance. In 2015, Bosch acquired Seeo to strengthen its position in electromobility and solid-state cell technology development.

Battery Technology

The company’s flagship innovation, DryLyte battery technology, represented a significant advancement in solid-state battery design. This system replaced traditional liquid electrolytes with a rigid block copolymer structure, effectively preventing dendrite growth – a common cause of battery failure. The technology offered multiple advantages over conventional lithium-ion batteries:

Enhanced safety through elimination of flammable components
Improved energy density for extended operation
Superior reliability in various temperature conditions
Reduced risk of internal shorts and explosions

The DryLyte system proved particularly suitable for automotive applications and stationary energy storage installations. Seeo’s manufacturing process utilized specialized equipment, including modified coating lines, stacking machines, and advanced pouch forming systems. This technical infrastructure enabled the production of batteries that met strict industry standards while maintaining consistent quality.
