Singapore scientists devise ‘fruity’ approach to lithium-ion battery circular economy

Wed, 09/02/2020 - 09:34 -- paul Crompton

Scientists in Singapore have come up with a 'fruity' way of finding an environmentally-friendly method of recycling lithium-ion batteries.

A team led by Nanyang Technological University, Singapore (NTU Singapore) has developed a method of using orange peel and citric acid to recover reusable metals from spent lithium-ion batteries.

US scientists develop cheap, environmentally friendly redox flow battery

Thu, 05/28/2020 - 15:44 -- paul Crompton

Scientists from the University of Southern California claim to have built a redox flow battery based on low-cost and readily available materials.

The key innovation involves using different fluids: an iron sulfate solution anD Anthraquinone disulfonic acid (AQDS), an organic material already used in some redox flow batteries for its stability, solubility and energy storage potential.

Indian researchers develop low cost graphene for supercapacitor applications

Thu, 01/09/2020 - 14:57 -- paul Crompton

Scientists at an Indian institute are working on pilot-scale production of reduced graphene oxide (rGO) after developing a process for generating functionalised graphene at low-cost.

The team at the Indian Institute of Science Education and Research, Pune (IISER) hope the technology will lead to the development of graphene-based supercapacitors for energy storage systems by the end of the year.
