Still someway to go then
"After 500 cycles, the capacity retention was a promising 83 per cent."
Since batteries for eVehicles are now achieving 90%+ at 2000+ cycles it will be a while before anyone swaps out their Li Ion for a chinese alternative.
OTOH if then can improve capacity retention they could be onto a world beater; I am always pissed off when my solar lamps garden retain enough charge for 30 minutes in winter when you need them most then miraculously revive in the summer with 6 hours just as you are thinking of replacing them. Sometimes make you think that garden lamps semi-sentient.
