Eer - if this is even remotely close to being true and scaleable this would be an enormous leap forward

The application of these batteries is for aviation more than anything else, you might see them in a BEV Ferrari or something though. BEVs seem to be moving from NMC to LiFePO4 (cheaper but lower power density).
Would be exciting to see domestic and short-haul aviation move to battery-electric platforms though...

Anyone noticed the over-hyped chinese claim?
BATTERIES Chinese Researchers Announce 711 KWh/Kg Lithium Battery
Upper case for kilo, too.
A sensible title might read ‘over 700Wh/kg’, but quoting to three significant figures immediately rings bells of idiotic claims/reporting - whether from the source of from the ‘journalists’.

Note: to get to the 500 Wh/kg **pack** density to make short haul passenger aviation viable, you need >1000 Wh/kg at **cell** level. Making a safe & certifiable battery pack for aviation use is both expensive and heavy.
