Good gawd, Drivel was right, after all.

at what voltage though. 3 times the mah is not much point if the cell voltage drops a factor of 3 :-) I can do you a lot of mah per gram in a

2v battery.. :-)

Only 13A at 240 kV though!

As a matter of irrelevance, an elderly friend of mine who sadly developed dementia has gone for a year with the NHS refusing to pay for his care. On investigation it turns out that he was down as having been sectioned and consequently they assumed he was in a special care home where charges go automatically to the NHS. In fact he has been in a private care home, at great cost to the family. There's now a barney going on about reimbursement.

They thought he'd been sectioned because he very nearly was, a year ago, when he was playing up rather a lot and wouldn't take his meds or leave his home to go to hospital.

Simples ... convert all pylons next to roads into charge stations :-)

Seems the common 3.7V flavour of Lithium ion batteries are lithium nickel manganese cobalt oxide cathode with graphite anodes

Sure. I've been trying to see what effect they say substituting a silicon anode for a graphite one would have on battery voltage, I think the graphite anodes are "inactive" within the the normal 3.7V Li-ion battery chemistry, so perhaps none at all.

They do sprinkle in encouraging phrases such as "no significant effect on the battery working voltage" but I daresay the chemistry of rechargeable Lithium cells is well beyond schoolboy Zn/Cu red-ox equations.
