About The Position

Nayan Banik will join as a non-paying visiting student to conduct advanced structural characterization of lithium-ion and sodium-ion battery materials provided by Dr. Daniel Abraham from the Chemical Sciences and Engineering (CSE) Division. The primary objective is to correlate local atomic and electronic structure and microstructural evolution with electrochemical performance metrics. The research will use electron microscopy facilities, including TEM, SEM, and FIB. TEM techniques include HRTEM, STEM, high-resolution EDS and EELS mapping, 3D electron diffraction, and 4D-STEM to map strain, phase distributions, and interfacial degradation mechanisms. The entirety of the appointment must be conducted in the United States. The student must be actively enrolled at, or recently graduated from, an accredited academic institution.

Requirements

• Knowledge of transmission electron microscopy modalities, including HRTEM/STEM, EDS and EELS spectroscopic mapping, 3D electron diffraction, and 4D-STEM data collection and analysis.
• Basic understanding of lithium-ion and sodium-ion battery chemistry, degradation mechanisms, and interfacial microstructures.
• Strong analytical problem-solving abilities.
• Proficiency with data processing software for microscopy and spectroscopy evaluation.
• Effective written and verbal communication skills for cross-divisional research collaboration.
• The appointment must be conducted entirely in the United States.
• Must be actively enrolled at, or recently graduated from, an accredited academic institution.

Responsibilities

• Conduct advanced structural characterization of lithium-ion and sodium-ion battery materials.
• Correlate local atomic and electronic structure and microstructural evolution with electrochemical performance metrics.
