JNCASR and Dreamfly Innovations Collaborate on Aviation Battery Tech

The Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) has partnered with Dreamfly Innovations, a Bengaluru-based company, to develop advanced thermal materials for aviation batteries. This collaboration, formalized through a Memorandum of Understanding (MoU) on January 24, 2024, aims to enhance thermal management in aviation battery systems.

Under this partnership, the focus will be on creating innovative thermal materials and thermoelectric devices designed to improve both thermal storage and conversion. The joint efforts are geared towards addressing significant challenges in aviation battery technology, translating fundamental materials research into viable thermal solutions for real-world applications.

Addressing Thermal Management Challenges

Effective heat management is critical in the aviation sector, especially for high-energy-density lithium-based batteries. Excessive heat generated during high-power operations can lead to reduced efficiency, shortened battery lifespan, and potential safety hazards.

The Ministry of Science and Technology highlighted that while passive thermal management methods like Phase Change Materials (PCMs) are appealing due to their lightweight and low power consumption, their adoption has been hindered by poor thermal conductivity. Conventional PCMs are unable to absorb heat quickly, causing temperature increases that accelerate degradation of battery components.

To overcome these limitations, the collaboration will explore the incorporation of high-thermal-conductivity additives to create composite PCMs. However, these composites face challenges such as long-term stability issues, including the agglomeration of additives during thermal cycling, which can degrade performance.

Innovative Solutions for Aviation Batteries

The advanced thermal materials being developed are expected to feature high thermal conductivity, enabling rapid heat absorption during high-load operations. This approach aims to maintain battery temperatures within optimal ranges, facilitating lightweight thermal regulation without sacrificing long-term stability.

The partnership brings together the academic expertise of Prof. Kanishka Biswas from JNCASR and the engineering prowess of Dreamfly Innovations. Together, they aim to tackle critical issues affecting drone performance, safety, and operational endurance, ultimately enhancing the viability of aviation battery technologies.

This collaboration underscores the importance of merging academic research with industrial innovation to drive progress in the aviation sector. As the demand for more efficient and safer aviation batteries continues to grow, initiatives like this will play a vital role in shaping the future of aerial technology.
