Li-Ion battery technology update. (From #idf09 session)

Posted on 22 September 2009, Last updated on 19 November 2012 by

I’m reporting from the IDF09 battery technology session.

Here’s what’s been happening in Li-Ion tech.

“3% per year improvements in capacity (watt-hours) inch If you ask me, that’s peanuts. Chemistry research not keeping up with Moore’s Law ;-)

Battery packs aren’t just cells…

11:27 am.

Trends Thin and light systems and their effect on battery packs. Here;s a nice diagram that explains how cell types affect design.

Prismatic cells 40% more expensive for same capacity.

Clearly cylindrical cells are more common.

Next few years:

More than 2600mah in a standard cell. (the ‘18650’ cell)

11:30 Sasmung now talking.

Samsung say 33% of customers willing to pay $45 for an extra hourCapture_00015

Getting technical now…. Samsungs secret sauce for 3.0A

New technologys…. Silicon based anode. Getting too technical for me here!!!!

Bottom line: 30% improvement in Q3 2010. Sounds too good to be true. I’ve heard these sort of promises before!

That’s all from the battery technology session at IDF09. I’ll continue to report on mobility topics at MeetMobility so check back regularly for updates.

    In recent years we’ve heard of nanowire li-ion batteries, new cathode materials/structures that improve charging speed etc. and all sorts of discoveries that have been cautiously predicted to exit the laboratories and enter the markets within about a decade. It was nice to read about the short term visions for a change!
