Energizer Lithium?

[Chris Doughty]

I have seen the adverts on TV for these things...

these are non-rechargable so that gets around the miss-use when charging problem, but what stops them deep draining past their safe state? they are out there for jonny kid to go and buy and put in his Wii-mote and use till they don't work anymore, will they go volotile use like this?

still, its interesting to see Lithum getting into 'regular' cell sizes like AA

Those cells are lithium ion though instead of lithium polymer, they just die on a dead short instead of being volitile. The problem with lithium ion is their life degrades with age as opposed to charges and this is vastly effected by their operating temperatures.

Li-ion are used in dSLR's quite a lot.

It's lithium iron as apposed to lithium polymer and is widely used in phones and laptops so is well tested and already mainstream :)

It's the polymer in the battery that is flammable but some companies are now using non-flammable polymer. Or solid polymer in some cases.

Ye, my phone has a 950mAh LiPo in it :D (SE)

Lithium/Iron Disulphide is quite safe, the cells have a PTC device built-in (protecting against short-circuit) and they don't generate any more dangerous chemicals once discharged.
The only real danger is if you puncture the cell (like with something sharp) then the fumes / fire are more toxic than alkaline.
They are prohibitively expensive, Duracell M3 ultra performs almost as well until you are talking sub-zero temperatures or really high currents.

When I worked for Energizer Power Systems, I was part of the European OEM team on the introduction of the Energizer Lithium.. it was called the L91 then... it kicks ass in highdrain applications and at low temperatures, so it is great for DSC's etc. dont bother buying them for RC Transmitters etc as these are low drain and you dont see the benefit as much. We used them in a battery backup battery for the Audi A8 also due it's ten year shelf life.

Lithium has been used for YEARS in battery products, cameras, watches etc but they are 3V systems where as this is closer to 1.5V making it suitable as a drop in replacement for AA etc...
