A team of Indian scientists have used nano-materials to develop Sodium-ion (Na-ion) based batteries and supercapacitors, which can be rapidly charged and have integrated them in e-cycles.
The low-cost Na-ion-based technologies would be cheap and are expected to reduce the cost of the e-cycles significantly.
Sodium-ion (Na-ion) batteries have triggered academic and commercial interest as a possible complementary technology to lithium-ion batteries because of the high natural abundance of sodium and the consequent low costs of Na-ion batteries.
Dr Amreesh Chandra, a professor in the Department of Physics at the Indian Institute of Technology Kharagpur, has been researching to develop energy storage technologies, which are based on Na-ion, and his team has developed a large number of nanomaterials, the Science and Technology Ministry said in a release on Wednesday (6 July).
The team has used sodium iron phosphates and sodium manganese phosphates which they synthesized to obtain Na-ion-based batteries and supercapacitors with support from the Technology Mission Division (TMD) of the Central government's Department of Science and Technology (DST).
These sodium materials were combined with various novel architectures of carbon to develop a battery.
These sodium materials are cheaper than Li-based materials, high performing, and can be scaled up to industrial-level production.
The Na-ion cell can also be totally discharged to zero volt, similar to a capacitor, making it a safer option in comparison to many other storage technologies.
Taking advantage of the fact that Na-ion batteries can be charged rapidly, Dr Amreesh has integrated it in e-cycles – an easy, affordable option for the general public, the ministry said.
