Much of the cost arises from expensive lithium sulfide salt ... But the mixture had poor ionic conductivity, a property that would lead to batteries that charge slowly and hold less energy ...

In the first study, a team led by Professor Jong-sung Yu at the DGIST Department of Energy Science and Engineering developed a nitrogen-doped porous carbon material ...

Sulfur has been suggested as a material for lithium-ion batteries ... capacity after 300 charge-discharge cycles. Next, the ...
