IIT Madras designs room temperature sodium sulphur battery

IIT Madras researchers have fabricated a new sodium sulphur battery that can be operated at room temperature and not at 300 degree C as is the case now. They achieved higher charge storage capacity and 83% retention of capacity even at the end of 500 cycles. While conventionally sodium sulphur batteries require very high temperature … Continue reading IIT Madras designs room temperature sodium sulphur battery

IIT Madras registers initial success with iron ion battery

Researchers from IIT Madras have for the first time fabricated a rechargeable iron ion battery using mild steel as the anode. The iron ion battery is cost-effective and has 54% capacity retention at the end of 50 cycles. It has 55-60% of lithium ion battery’s performance. Indian Institute of Technology (IIT) Madras researchers have for … Continue reading IIT Madras registers initial success with iron ion battery

Cutting down tailpipe emissions with e-vehicles

At nearly 55%, electricity generation in India is primarily through coal. So like in the case of the U.S and China, net reduction in carbon emission will not be much even when if there is large-scale adoption of electric vehicles in India. Still, cities and towns using electric vehicles in large numbers will see a reduction … Continue reading Cutting down tailpipe emissions with e-vehicles

Podcast: Increasing Li-ion battery’s capacity, charging speed

Kingshuk Roy of IISER Pune explains how the novel anode made of silicon-phosphorene mixture for use in Li-ion batteries has five times more capacity than carbon-based electrodes and can be fully charged in about 15 minutes. The researchers used just 8% of phosphorene to dramatically improve the stability of silicon electrode. The electrode showed no … Continue reading Podcast: Increasing Li-ion battery’s capacity, charging speed

IISER Pune’s novel anode increases Li-ion capacity, quickens battery charging

IISER Pune researchers have fabricated a novel anode made of silicon-phosphorene mixture for use in Li-ion batteries. The anode has five times more capacity than carbon-based electrodes and can be fully charged in about 15 minutes. The electrode showed no discernible cracks even after 250 cycles of charging and discharging. A novel anode developed by … Continue reading IISER Pune’s novel anode increases Li-ion capacity, quickens battery charging

IISER Kolkata: Paper-based electrodes show superior water-splitting efficiency

Researchers at IISER Kolkata have used a paper coated with nickel nanoparticles and model catalysts to split water to produce hydrogen gas. The flexible electrodes recorded 98% water-splitting efficiency and maintained robustness and durability even after more than 10 continuous days of operation. Using paper coated with nickel nanoparticles and model catalysts as electrodes, researchers … Continue reading IISER Kolkata: Paper-based electrodes show superior water-splitting efficiency

IISER Pune makes novel anode for next-generation batteries in electric vehicles

Research at IISER Pune have synthesised a new type of anode material that offers promise of a battery that can be charged quickly and retain the charge for longer duration of travel, thus making frequent charging unnecessary for electric vehicles. The drop in charge even when the battery is charged rapidly is higher than graphite … Continue reading IISER Pune makes novel anode for next-generation batteries in electric vehicles

IIT Madras develops a novel electrode material for lithium batteries

A team of researchers at the Indian Institute of Technology (IIT) Madras has been able to enhance the capacity retention of anode material in lithium ion batteries four-fold compared with commercially available ones. The team was able to develop a novel composite which can deliver specific capacity retention of 1,120 mAh/g after 10,000 cycles, and … Continue reading IIT Madras develops a novel electrode material for lithium batteries

Voila! NPL scientists produce electricity from water without using electrolyte, light

In a major breakthrough, scientists at Delhi’s National Physical Laboratory (NPL) have developed a novel way of producing electricity from water at room temperature without supplying any external energy or using electrolyte or light. A team led by Dr. R.K. Kotnala used nanoporous magnesium ferrite to split water into hydronium (H3O) and hydroxide (OH) ions … Continue reading Voila! NPL scientists produce electricity from water without using electrolyte, light

Electric bicycles from Chennai to hit the road soon

The Chennai-based Basil Energetics is ready to launch an electric bicycle, iZip, in Hyderabad by the end of this month. Fitted with a long-lasting and light-weight portable lithium iron phosphate battery (like the ones used in Tesla and Toyota), iZip can travel at a top speed of 20 km per hour. The cycle, which weighs … Continue reading Electric bicycles from Chennai to hit the road soon
