Lithium-ion batteries, future of weapon systems

Lithium-ion batteries will replace all batteries in the defence and space sector. It is the future of battery technology and set to replace the lead-acid models, said Chairman of DRDO and Secretary of Department of Defence R&D Dr. S. Chirstopher here on Saturday.

Delivering the inaugural address at the one-day workshop on ‘Indigenous lithium-ion batteries for special applications’ organised by the Naval Science and Technological Laboratory (NSTL), he said innovation was the buzzword and “we have to innovate to make best use of the available technology.”

Introducing the technology to the participants, Dr. O.R. Nandagopan, Director NSTL, said development of the batteries was at an advanced stage at the NSTL and it would be rolled out sometime in 2019.

According to Dr. Nandagopan, cell phones had revolutionised the use and need of lithium-ion batteries and in India it was in the development stage. A. Srinivas Kumar, Technology Director, Battery and Explosives, NSTL, pointed out that R&D in this field was the need of the hour to reduce the dependency on imports. Dr. Sameer Kamat, Director General, Naval Systems and Materials, pointed out that indigenous development was important.

Key component

Rear Admiral V. Srinivas, Flag Officer, Submarines, ENC, said batteries were a key component in all variants of submarines be it the latest Scorpene or the nuclear-powered Arihant class of submarines. “Till now we have been using the lead-acid variant of batteries and we need to migrate to the lithium-ion type for their high energy and high power density capability. This variant of batteries will allow us to lie deeper for a longer period,” he said.

Delivering the keynote address, A.K. Shukla from IISC-Bangalore, highlighted the pros and cons of the lithium-ion batteries and urged the R&D to focus on quality, as they were susceptible to explosions.
