Abstract: India’s transition toward a renewable-intensive energy system has incentivized the need for alternative energy storage technologies that are cost-effective, safe, and compatible with national resource availability. In this context, Sodium-Ion Batteries (SIBs) have emerged as a strategically relevant option, particularly for stationary and grid-scale applications. However, a consolidated assessment of India’s readiness for SIB development, encompassing scientific progress, industrial capability, and policy support, remains limited. This study attempts to address the gap through an India-centric, perception-based survey designed to evaluate challenges and priorities associated with SIB research and deployment. An online questionnaire was administered across India, yielding responses from 102 Indian participants actively engaged in sodium ion battery research who have already published work in the field. The survey integrated Likert-scale perception statements, multiple-choice priority questions, and open-ended responses. Quantitative data were analyzed using percentage-based distributions, while qualitative inputs were examined through thematic analysis to identify recurring expert perspectives. The findings indicate cautious optimism regarding India’s progress in SIB research, alongside clear recognition of persistent bottlenecks, particularly low energy density, limited cycle life, and electrode–electrolyte instability. Application-level insights point toward stationary and grid-integrated storage as the most viable near-term deployment pathway, whereas industrial adoption is constrained by manufacturing scale-up and supply-chain limitations. Policy-related responses emphasize the importance of mission-oriented funding, pilotscale infrastructure, and strengthened industry–academia collaboration. Collectively, the survey offers evidence-based insights to inform strategic planning for India’s evolving energy storage ecosystem.
