Battery Development Scientist (Solid-State / Li-ion)

Our client is a Singapore-based sustainable battery technology startup building safer, greener and more circular energy storage for consumer electronics, logistics and large-scale applications. Its R&D team is expanding into solid- and semi-solid-state battery technologies to speed up commercialisation. What You'll Do • Research and develop solid-/semi-solid-state and next-generation battery chemistries • Design and synthesise new electrode, electrolyte and separator materials • Assemble and test coin, pouch, cylindrical and custom cell formats • Run electrochemical characterisation (CV, EIS, GCD, cycle life, rate performance) and study degradation and interfacial behaviour • Optimise cell design parameters (electrode loading, N/P ratio, electrolyte/cathode ratio) and benchmark against commercial Li-ion • Scale lab results into manufacturable processes and prototypes • Contribute to patents, and present prototypes at conferences and industry events • Uphold lab safety and compliance with relevant battery standards (ISO, UL, EU) Must-Have Requirements (Non-Negotiable) • PhD in Materials Science, Electrochemistry, Chemical Engineering or a related field • Hands-on experience with Li-ion batteries • Experience with solid or semi-solid electrolytes for Li-ion batteries • Industrial experience in battery R&D, development or manufacturing (not only academic) Core Key Skills • Electrochemical cell assembly and testing • Glovebox handling and wet-chemical synthesis • Analytical techniques such as XRD, SEM/TEM, XPS, Raman and ICP-MS • Strong grounding in electrochemical theory and kinetics • Published battery research • Clear communication and comfort working in a multidisciplinary team Nice to Have • Computational modelling or machine learning for materials discovery • Experience scaling lab processes to pilot or production • Patent filing experience
