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 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

Pune researchers use bagasse to produce anode-grade carbon for Li-ion batteries

Now, researchers from Pune’s National Chemical Laboratory (NCL) and Indian Institute of Science Education and Research (IISER) have used a simple, cost-effective, quick process to convert sugarcane bagasse, an agro waste, into anode-grade porous, conducting, activated carbon material for use in Lithium-ion batteries. While making anode-grade carbon is currently very expensive and time consuming, the Pune … Continue reading Pune researchers use bagasse to produce anode-grade carbon for Li-ion batteries
