TNT has 1162 Wh/kg ratio.

These new lithium-ion batteries get to 300-400Wh/kg range.

We are hitting the limit what is doable with energy density. Do you really want to carry 100g of TNT in your pocket or few tons of TNT in vehicle going 100km/h.

Of course things are not directly comparable, but ball parks.

I think the real breakthrough will come when we will be able to make powerful microbatteries.
