It feels like batteries are getting closer to a breakout, Wh/kg estimates each year recently keeps getting beat, we’re at 500 Wh/kg now, by mid 2030s we might reach 1000 Wh/kg,

Global battery sales continue to grow YoY, we're in 1GWh/y territory now

creating and destroying; built flying cars & autonomous vehicles, now building /faust, more here: /july, web: july.rocks

It's interesting to note this flywheel / feedback loop

Increase energy density -> more people buy it
more people by it -> decreases cost
cost decreases -> increases demand
increased demand -> need more increase in energy density

repeat

For context:

In June 2024, we're at 720Wh/Kg !!!

In 2019, predictions were around by 2035 we will reach 400~500 Wh/kg or more

Lol

Crazy to say that since we keep beating estimates, it seems like we're just getting started

Super interesting! I’ve been hearing more about them lately, this makes sense 

Thanks for sharing

increase energy density and unlock new types of vehicles

You speak on demand but lack what innovation takes us to the step level efficiency needed

continued increase in battery energy density + cost reduction means:
- cars: more EV range, faster charging, lighter vehicles
- bigger cars: longer range electric buses, first light trucks
- grid storage: improves peak shaving
- heavier trucks: eventually all trucks
- all trains & ships
- anything that flies = electric

What experiences its renaissance with these efficiency and cost gains?

Energy is being stored fr. 
Don’t tell Saylor.

we're just gonna hope for the engineers and real workers, not us

Is 500 Wh/kg in production or the lab? How fast is energy density moving from the lab to production at >megawatt scale?
