Waits for Duracell Bunny series phone to be released.
But about time companies focused on better battery life.
How many kg? 2?

I've just come out of hospital so I may have got my maths wrong but to give you an idea of how silly this is from a purely safety perspective.... you're carrying this around in your pocket, right? Running at 3.7V with 16Ah gives me an energy capacity of 213,120 Joules. A common model of hand grenade carries equivilent of 60g of TNT which contains 267KJ. And we've all seen the occasionally catastrophic failure modes of lithium cells with only 3Ah. You don't need to have a faulty cell, you just need it to be pierced in a car accident. It's a HUGE amount of energy to be packing into a relatively poorly protected package with known catastrophic failure modes.

Oh absolutely, car fires are amazing things and the design of your average fuel tank is nothing short of magic. These things should be popping into flames left right and centre but engineering means they don't. Fords in particular love to go up in flames - look up their current exhaust igniting dry grass off roader for an example of true engineering retardation (well, it's actually the DPF regenerating) and the fact that they are still selling the faulty models without a fix in place for an example of true customer care (well, that was the state of play last week before I ended up a guest of the NHS, I haven't caught up yet). Contrary to popular belief, petrol does not explode however and safety mechanisms in place give you time to escape (although it's seriously not much - once it gets into the cabin you've got well under ten seconds or you're literally burned alive). The phone catastrophic failure mode is coped with via venting the energy in a particular direction (assuming the cell is intact). All manufactured products have all their characteristics within a bell curve and there WILL be failures, hence the reason for the venting system - it gives some control over the energy release. As for a "safety protected" cell - it really isn't as far as physical protection from damage goes and that is gonna be the cause of a runaway / catastrophic failure. Anything with this much energy should be charged in a fireproof bag - plenty of them on sale for model aeroplane batteries, etc.
The difference between this and a car is that one is catching fire several meters from you whilst the other is riiiight next to your family jewels.
If you asked me whether I would rather carry a (properly stored, maintained, assembled and issued) hand grenade in my pocket or a phone with a battery this big, I'd actually go with the grenade.

60g is fairly low for a hand grenade, but it's the right order of magnitude. In a car accident the car battery would be a bigger concern - 12 V at 50-60 Ah (2.4 MJ), and many new cars have lithium cells for lightness
In the grand scheme of things you're more likely to have testicular cancer from the phone than it explode though....
But I get the point. Still not the biggest chance of injury in a car though from a phone battery cell accident. A nice big handful of other things likely to kill you first in a crash

I'm in Warwick.... but if you'd ever been to Rugeley you'd understand lol

Again it's proximity rather than overall hazard. For example the hoverboards going up with dicky batteries wasn't a massive issue as it was just far enough away to avoid severe damage and you can just hop off and enjoy the inferno. Ban them on aeroplanes and so on and you're all good. Samsung Note 7 however.... these are in the pocket and in order to remove it you're going to be putting your hand into your flaming pocket (which will probably have melted into your skin depending on the fabric), they're being charged next to beds overnight... oh the fun a pyromaniac hacker could have.
And I just picked the first grenade Google (no, Duckduckgo) gave me that listed the energy in something I could easily turn into Joules...
Also, on a tangent, have you seen the size of the batteries on the cars with stop-start? My fiance's Fiesta must have a bigger battery than it does engine.... That said, my bike has a bigger engine than her car, so that's not saying much.
