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.

Flow battery report shows benefits to port but could the tech one-day power ships

Fri, 07/17/2020 - 09:40 -- Paul Crompton

A six-month feasibility study at Portsmouth, UK, port has demonstrated how flow batteries offer a more cost effective solution to reducing the shipping industry’s emissions than conventional lithium-ion and lead-acid batteries. 

Despite being larger than traditional batteries per kWh the Shore Power for Shipping (SPIDS) project found flow batteries can reduce the peak power of a port’s network connection to only 10-20% of the grid power required using traditional batteries.

New cathode coating extends lithium-ion battery life and boosts safety

Tue, 07/14/2020 - 12:42 -- Paul Crompton

A three-year project by the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Hong Kong University of Science and Technology (HKUST) has made a breakthrough in improving lithium-ion batteries.

Researchers used a coating called PEDOT to completely protect each particle of the cathode — inside and out — from reacting with the electrolyte, which improves lithium-ion battery cycle life and safety.
