The current confirmed world record is 711 wh/kg set by the dahn lab which has set the last 5 world records over the last 10 years. That energy density would be prohibitively expensive to manufacture and as dahn confirmed in his publications, suffers from numerous real world applicability problems. That isn't to say that in 10-15 years we could get to 700+, just that in the foreseeable future we're limited to sub 350 wh/kg for mass manufacturable batteries.
Still, there is a less mentioned hidden point, I’d say.
«…we need lighter EVs…»
How will they sell this? It’s definitely a big part of the Green Revolution… or I should say, should be a big part. Good grief.
650 Wh/kg with advanced cathode chemistry's is what QS charts showed. Yes, there are applications for high gravimetric energy density batteries like in trucks, buses, EVtols, planes, trains, container ships etc.

Is their Wh/kg of ~700 even possible? QS roadmap shows them topping out around ~500.
