IEEE to Create New Battery Standard

Darn those pesky exploding batteries
This week the IEEE consortium announced that it has started work on a
new standard that would regulate how lithium-ion and lithium-polymer batteries are designed
and manufactured. The standard, called IEEE P1825, will set forth a number of criteria for battery design, construction and packaging in order to avoid some of the recent incidents involving lithium batteries.
For the longest time now, lithium-based batteries have been known to give reliable service as well as being safe. Unfortunately, being produced in greater quantities today, lithium batteries have fallen by the way side in terms of quality control. Sony, one of the world's largest manufacturers of lithium batteries is
currently under heavy investigation because its batteries have been involved in a number of recent fires
Over the last several weeks, a number of manufacturers have recalled batteries that were manufactured by Sony. Just last week,
Toshiba recalled 340,000 batteries
which were manufactured by Sony but used in its products. A day before that,
Virgin Atlantic banned any products that used either Dell or Apple batteries
-- all manufactured by Sony. Interestingly, in late August Sony announced that there would be
no more battery recalls for units it produced
. Despite the optimism, many batteries continue to be returned to their respective manufacturers.
The IEEE is hoping to have completed standards that cover both notebook batteries as well as batteries used in mobile phones by the end of 2006.

That is exactly what they have chosen not to do and should not do!
LIthium Ion requires a special charger and should not be made to fit in legacy chargers for NiCad or NiMH. This is very important and the only other alternative would be to integrated a separate cell protection circuit inside every cell, one quite comprehensive, which will make all batteries larger but particularly on the smaller AAA or AA, drastically reduce capacity to allow the room for the circuit (and raise cost due to this redundant circuitry, as not all of it needs be redundant for protection). Temp cutout would be useful, but overcurrent on devices always using series cell packs need not be per-cell in multi-cell packs.
Plus, there's that issue of them being a different voltage. Ultimately I hope they instead find an alternate chemistry that is reasonably affordable, offers higher energy density than NiMH, but is safer than Li-Ion. Until then, I think we need to differentiate Li-Ion but not having standardized formats meant to mimmick Alkalines.

Doh! The post was that there should be some standard sizes in the future, not to copy the dimensions of AAA or AA. Nobody was suggesting that.
To help you understand the concept of standardisation, the market has created a number of standardised memory formats. The new flash formats like CF or SD etc. Thankfully, we can all go to an electronics store (or online) and buy a CF or SD memory to fit into our consumer electronics devices. (Except SONY! LOL). The post was to point out that it would be equally helpful to have a battery standard. Can you imagine if EVERY ELECTRONICS DEVICE and EVERY MANUFACTURER had a different memory format?! Just transfer this concept to battery and you will understand the thesis of the HOPE post.
