Winner in the "Yeah, right" category: "Theoretical Energy Density: Up to 12,000 Wh/kg — roughly matching gasoline. This is a massive leap over today's best EV batteries (~250–350 Wh/kg)."
I have a game changing idea!!
Gas is so energy dense, let’s just use that!
.
“Theoretical Energy Density: Up to 12,000 Wh/kg — roughly matching gasoline. This is a massive leap over today’s best EV batteries (~250–350 Wh/kg).””
No you are comparing first law vs second law thermodynamics.
While the raw energy density is the same per kg of mass the outputs of energy from the systems are not.
Electric motors turn 98% of electron flow into physical torque and there for work by definition.
Internal combustion beings a first law machine must obey Carnot and can never turn more than 70% of the same energy density per kg into at the crankshaft torque. Given the temps that are achievable with combustion in a 80/20 mix of N2 and O2 this does not include what steel or even ceramics could survive you would instantly melt both at such temps. The very best ICE in a motor vehicle in hybrids from China I might add are in the 45% LHV to torque range.
So it’s 45% max vs 95-98% first law vs second law, this means on a per kg basis electrons win two to one.
So no while they match in bulk density they do not match in useable energy output to the wheels not even close. That’s how physics works.
This doesn’t include that EV don’t have hydraulic automatic transmissions eating even more of that engine torque on the way to the wheels. Electric motors have max torque at zero rpm they don’t need a hydraulic torque converter to moves vehicle and they don’t need to idle against a slipping fluid clutch that is just turning torque and therefore fuel into useless heat waste.
