Here is all you need to know about the amazing breakthrough in nanotechnology that can make better rechargeable batteries, all thanks to researcher Gurpreet Singh, who recently won a whopping $500,000 award for further developments in the field.
Here is another good news in the field of Research and Development. Gurpreet Singh, an Indian-American researcher, has won a $500,000 National Science Foundation Career award for his work on nanosheets.
This assistant professor of mechanical and nuclear engineering at Kansas State University has done extensive research on “Scalable liquid exfoliation processing of ultra-thin two-dimensional metal dichalcogenides nanosheets for energy storage devices,” as per the University release.
The award money will be used by him for further research that can help to produce better rechargeable batteries, supercapacitors and catalysts for photo-electrochemical hydrogen production.
“Most negative electrodes for sodium-ion batteries use materials that undergo an ‘alloying’ reaction with sodium. These materials can swell as much as 400 to 500 percent as the battery is charged and discharged, which may result in mechanical damage and loss of electrical contact with the current collector,” Singh told Microfinance Monitor.
A part of the award money will also be used by Singh to set up educational activities for high school science teachers and female students in the field of nanotechnology.
“I want to create excitement about the opportunities in nanotechnology and also make others aware of the challenges related to scalable manufacture and high-cost that is currently hindering its introduction in practical applications,” he informs.
There is very little awareness about Transition Metal Dichalcogenides (TMD) and their mechanical, electrical and electrochemical properties. Singh plans to study the large-scale production of ultra-thin sheets – a few atoms thick and several micrometers thick – of TMDs. Around 40 types of TMDs have been identified, including naturally occurring molybdenite.
For energy applications like rechargeable batteries, supercapacitors and catalysts for photo-electrochemical hydrogen production, huge quantities of nanosheets are required. But, currently, no method meets the need of producing atomically thin TMDs in large quantifies at affordable rates. Singh’s research will focus on making this possible.
“For long-term sustainability, it is important to look at alternative energy production routes as well as methods for efficient energy storage and distribution,” Singh has said in a Kansas University press release.
Singh’s research stands out as it is the first time that such a flexible paper electrode was used in a sodium-ion battery as an anode that operates at room temperature. Most commercial sodium-sulfur batteries operate at around 300 degrees Celsius.
Singh’s amazing work and research in the past includes using graphene oxide to improve sodium- and lithium-ion flexible batteries and creating carbon nanotubes for better laser detectors and rechargeable batteries.
Further research will be done to commercialise the technology. We congratulate Singh on his amazing breakthrough and hope to see some very useful innovations through his research.
