Thiruvananthapuram: In a major achievement, a prototype of the state’s indigenously developed Lithium Titanate Oxide (LTO) battery has been manufactured by a consortium led by the Kerala Development and Innovation Strategic Council (K-DISC).

The battery, which is aimed towards setting up an e-vehicle ecosystem in Kerala, is being developed under the joint efforts of Vikram Sarabhai Space Centre (VSSC), Travancore Titanium Products Limited (TTPL) and K-DISC. The LTO prototype (20 Ah) was unveiled by Industries Minister P Rajeev the other day.

The achievement is considered as Kerala’s step towards the development of low-cost, high capacity and safe batteries suitable for electric vehicles.

“We decided to move ahead with such a venture upon realising that LTO could be easily obtained from TTPL as per requirement. All the parts of the battery were imported from China. We tried to find out if we could manufacture lithium electrodes from the LTO obtained from TTPL,” said Ashok Kumar A, electric vehicle division consultant, K-DISC.

In addition to the Centre for Development of Advanced Computing (C-DAC), the Trivandrum Engineering Science and Technology (TrEST) Research Park, which was set up for technical research activities, is also part of the electric vehicle consortium.

“We have to bring about some more modification. Afterwards, the battery technology will be handed over to companies for commercial production, Ashok Kumar added.
