Strategic Objectives
• Master the mechanics of stress and strain in solid electrolytes.
• Predict and prevent fracture-induced degradation in rigid cells.
• Optimize stack pressure to maintain seamless interfacial contact.
• Engineer robust architectures that withstand thousands of cycles.
The Core Challenge
Traditional battery models ignore the destructive physical forces that cause rigid solid-state interfaces to fracture and fail during expansion.
