Re: How many battery "breakthroughs" @ DainB
May I leave it to you to figure out why wood which is 4 times as energy dense as TNT does not produce same result when it is releasing all that energy ?
Because wood usually exists as a discrete physical block, and that prevents the fuel from being exposed quickly to the oxidising agent fast enough to cause an explosion. However, that's for a lump of wood. If you have wood dust it most certainly is explosive because the oxidising agent and the fuel can be mixed to the perfect proportions. Operators of wood pellet power stations and sawmills know this, often from costly experience, and there's Youtube videos of real world wood dust explosions (coal, flour, corn dust, even sugar will do the same). Scan to 30 seconds into this:
TNT and most other explosives don't rely on atmospheric oxygen, they contain their own reagents, and so does a battery. Given the sort of explosions a conventional lithium battery can achieve if short circuited, I wouldn't want to be around one with three times the energy density.
