What is a Grand Battery Science Challenge? A grand challenge is a fundamental problem in battery science or engineering, with broad applications and implications, whose solution would be enabled by the application of next generation characterization tools that could become available in the near future ++ ++ Example Solvation-Desolvation Dynamics What is the solvation shell structure? How does solvation shell affect mobility and stability? What are the interactions among solvation shells? How does de-solvation at the electrode interface control SEI, intercalation and chemical reaction?
Guidelines for Priority Research Directions • Next generation characterization tools • Address a Grand Battery Science Challenge • In situ • Time resolved • Multi-modal • May be multi-institutional What do I want to measure that I cannot measure?
Priority Research Direction Title of PRD Major Development Challenges Science Grand Challenge Addressed What major experimental/modeling challenges must be overcome? What challenges prevent deploying this technique now? What are promising routes to overcoming the challenges? What unanswered science question will be addressed? What new characterization technique will be developed? Why is this an important science/characterization direction? Characterization Approach Potential Impact How will this PRD advance the frontier of battery science? • What features of x-rays, neutrons, electron microscopy and/or NMR will be employed? • What is the “big idea” of this approach? • How does this approach differ from existing ones? • What new characterization outcomes will be achieved? • Is this approach • In situ? • Time resolved? • Multi-modal?
