What is the significance of Sodium-Ion Batteries (SIBs) compared to Lithium-Ion Batteries (LIBs) for India?

SIBs offer a sustainable, cost-effective alternative to LIBs, utilizing abundant sodium resources instead of scarce lithium and cobalt. This reduces import dependency, enhances energy security, and supports India's transition to green energy. Their suitability for grid storage and low-speed electric vehicles makes them vital for achieving net-zero targets.

How does the use of bio-waste for hard carbon production align with India's environmental goals?

Utilizing agricultural residues for hard carbon production addresses the dual challenge of waste management and pollution from stubble burning. It promotes a circular economy by transforming bio-waste into high-value battery anodes. This indigenous technology supports the "Waste to Wealth" mission while reducing the carbon footprint of battery manufacturing.

What role does the Technology Development Board (TDB) play in India's technological landscape?

The TDB, under the Department of Science and Technology, provides financial assistance to Indian industrial concerns for the commercialization of indigenous technologies. By funding projects like bio-waste-derived hard carbon, it bridges the gap between laboratory research and industrial application, fostering a robust domestic ecosystem for innovation and self-reliance.

What are the primary applications and limitations of Sodium-Ion Batteries in the current energy sector?

SIBs are ideal for grid-scale energy storage, solar lighting, and low-speed electric mobility like e-rickshaws. While they offer better safety and low-temperature performance, they currently have lower energy density than LIBs. However, their lower cost and material availability make them a strategic choice for stationary and short-range applications.

How does this indigenous development contribute to the 'Atmanirbhar Bharat' initiative in the energy sector?

This project reduces India's reliance on imported critical minerals like lithium and cobalt, which are dominated by specific global supply chains. By developing a domestic supply chain using local agricultural waste, India strengthens its strategic autonomy in energy storage, supports local manufacturing, and advances the goals of the National Mission on Transformative Mobility.

The Technology Development Board (TDB), under the Department of Science & Technology (DST), has provided financial support to Indigenous Energy Storage Technologies Pvt. Ltd. for the commercialization of hard carbon derived from bio-waste and agricultural residues. This hard carbon serves as a critical anode material for Sodium-Ion Batteries (SIBs). SIB technology is emerging as a sustainable and cost-effective alternative to traditional Lithium-Ion systems. By utilizing agricultural waste, the project targets two major challenges: effective waste management and the creation of a domestic supply chain for battery materials. These batteries are particularly suited for grid-scale energy storage, solar lighting, and low-speed electric mobility (e-rickshaws and e-scooters), significantly reducing India's reliance on imported lithium and cobalt.

TDB funds bio‑waste hard carbon to boost indigenous sodium‑ion batteries, cutting lithium imports

Key Facts

In 2026, the Technology Development Board (TDB) under DST approved financial assistance to Indigenous Energy Storage Technologies Pvt. Ltd., Roorkee, for commercialising bio‑waste derived hard carbon anodes for sodium‑ion batteries.
Hard carbon retains a disordered microstructure and porosity at high temperatures, making it suitable for Na⁺ intercalation and delivering high initial coulombic efficiency and stable cycling.
The project targets applications such as grid‑scale storage, UPS/inverter systems, solar street lighting and low‑speed electric mobility (e‑rickshaws, e‑scooters, e‑cycles).
Utilising agricultural residues reduces dependence on imported lithium and graphite, aligning with the Atmanirbhar Bharat self‑reliance drive.
Sodium and carbon are abundant and geographically dispersed, mitigating global supply‑chain risks associated with lithium.
The initiative embodies circular‑economy principles by converting waste into high‑value battery material, supporting renewable‑energy integration.
Project spokesperson Shri Rajesh Kumar Pathak, Secretary, TDB, highlighted waste‑to‑value technologies as key to building a resilient battery ecosystem.

Background & Context

India's push for a self‑reliant battery ecosystem dovetails with the need for large‑scale energy storage to integrate renewable power. By promoting sodium‑ion batteries made from domestically sourced bio‑waste hard carbon, the government addresses supply‑chain vulnerabilities, environmental sustainability, and the economic goal of reducing import dependence.
