Executive Industry Relevance

Rapid and predictive screening of electrode and electrolyte coatings is critical for advancing all-solid-state battery (ASSB) technologies, which are increasingly relevant for high-safety, high-performance energy storage. This in situ TEM-based workflow enables efficient evaluation of coating materials and thicknesses, directly supporting early-stage material selection and de-risking for next-generation battery platforms. The approach accelerates portfolio decisions by providing actionable data on coating stability and interface behavior under operationally relevant conditions.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct visualization of coating integrity and failure modes during dynamic (de)lithiation cycles.
• Supports mechanistic de-risking by clarifying how coating thickness and composition affect interface stability.
• Facilitates rapid triage of candidate coatings for further development based on real-time performance metrics.

Screening & Assay Development

• Provides a reproducible, low-dose electron microscopy workflow for high-throughput coating assessment.
• Generates quantitative outputs such as areal expansion rates and coating breakage thresholds.
• Standardizes screening conditions to enable reliable comparison across coating types and thicknesses.

Translational & Preclinical Research

• Aligns material selection with downstream manufacturability and long-term battery stability requirements.
• Supports continuity from discovery-stage screening to preclinical validation of coating candidates.
• Reduces risk of late-stage failure by identifying coatings with robust mechanical and electrochemical properties.
