Re: Your statement about battery packs - I believe this was the basis of the Compaq study. Their conclusion was that you could get 23% more active material in a battery pack. If the specific energy in wh/liter is identical, then Solid polymer can pack 23% more in an available space, as you could get 23% more beer with a 12 pack if you could include the space between the cans! Regarding watt-hr/Kg, the industry-standard 18650 Li-Ion cell with a more expensive cobalt cathode is about 90 watt-hr per Kilo. If you refer to Valence's may '97 spec sheets for their MnO2-cathode solid polymer, you can calculate about 145 watt/hr per Kg. With the diminishing size of portable electronic devices, wouldn't an OEM pay a little more to be able to pack 23% more energy into a space at about 60% of the weight? Regards, FMK
