TCG Group Explores Commercial Production of Indigenous Sodium-Ion Batteries
TCG Group is thinking about making special batteries in India that charge very fast and are made from local materials.
These batteries could be used in electric vehicles, powering the grid, and in places without electricity.
They're working on making these batteries in a big way in the next few years.
TCG Group may produce sodium-ion batteries commercially
Batteries charge up to 94% in 5 minutes, comparable to Li-ion in energy density
Made entirely from India-sourced materials, reducing supply chain risks
Potential applications: electric mobility, grid-scale energy storage, off-grid systems
RISE, under TCG-CREST, developed the technology and aims for industrial-scale deployment in 2-3 years
