Research Engineer

QpiVolta 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 Enginee...
