Research engineer

Qpi Volta is seeking a Sodium-Ion Battery Engineer to drive the development, optimization, and scale-up of sodium-ion battery materials and cells, with particular focus on hard carbon anodes, electrolyte–SEI engineering, ICE improvement, and pilot-line pouch cell fabrication.
This role requires strong hands-on experimental capability, deep electrochemical understanding, and the ability to translate lab-scale insights into pilot-line-ready processes.
Key Responsibilities
Sodium-Ion Anode & Electrochemistry
 Design, synthesize, and optimize hard carbon anodes for sodium-ion batteries
 Evaluate doped hard carbons (e.g., N-doped carbons) and their impact on ICE, SEI, and kinetics
 Study Na storage mechanisms, voltage profiles, and irreversible capacity loss
 Develop strategies to improve Initial Coulombic Efficiency (ICE) and cycle stability
Electrolyte & Interface Engineering
 Develop and optimize carbonate- and ether-based Na-ion electrolytes
 Investig...
