N1 - Funding Information:
Dr. Kelsey B. Hatzell is an assistant professor in the Andlinger Center for Energy and Environment and Mechanical and Aerospace Engi- neering Department at Princeton University. She earned her PhD in Material Science and Engineering at Drexel University, her MS in Mechanical Engineering from Pennsylvania State University, and her BS/BA in Engineering/ Economics from Swarthmore College. Hatzell was an ITRI- Rosenfeld Distinguished Post doctoral fellow at the Berkeley Lab before starting her independent research group. Her research group works on understanding phenomena at solid|liquid and solid|solid interfaces and works broadly in energy storage and conversion. Hatzell is the recipient of several awards including the ORAU Power Junior Faculty Award (2017), NSF CAREER Award (2019), ECS Toyota Young Investigator Award (2019), finalist for the BASF/Volkswagen Science in Electrochemistry Award (2019), the Ralph ‘‘Buck’’ Robinson award from MRS (2019), Sloan Fellowship in Chemistry (2020) and the equal opportunity award from the post lithium storage cluster of excellence (2021).

N2 - Electrification of the transportation sector relies on radical re-imagining of energy storage technologies to provide affordable, high energy density, durable and safe systems. Next generation energy storage systems will need to leverage high energy density anodes and high voltage cathodes to achieve the required performance metrics (longer vehicle range, long life, production costs, safety). Solid-state batteries (SSBs) are promising materials technology for achieving these metrics by enabling these electrode systems due to the underlying material properties of the solid electrolyte (viz. mechanical strength, electrochemical stability, ionic conductivity). Electro-chemo-mechanical degradation in SSBs detrimentally impact the Coulombic efficiencies, capacity retention, durability and safety in SSBs restricting their practical implementation. Solid|solid interfaces in SSBs are hot-spots of dynamics that contribute to the degradation of SSBs. Characterizing and understanding the processes at the solid|solid interfaces in SSBs is crucial towards designing of resilient, durable, high energy density SSBs. This work provides a comprehensive and critical summary of the SSB characterization with a focus on in situ and operando studies. Additionally, perspectives on experimental design, emerging characterization techniques and data analysis methods are provided. This work provides a thorough analysis of current status of SSB characterization as well as highlights important avenues for future work.
