Lithium-Thionyl Chloride — Special Mention

Although non-rechargeable,Lithium-Thionyl Chloride has the highest energy storage per kilogram of any battery type. Lithium-Thionyl Chloride cells do not supply high discharge currents, typically 1/10 the current of other cell types. However they last for 20 years, and withstand temperature extremes of -55 to +150 degrees C. For more information on Lithium-Thionyl Chloride batteries, contact Tadiran Battery Co.

Finally, if you would like a D-size battery that can supply 20 amperes of current for a short time (5 seconds), that will last for 10 years, check out the Ultracapacitor at Maxwell Technologies Inc. It is not really a battery at all, it is a 350 farad capacitor rated 2.5 volts. Yes, we said farads, not microfarads. As such it can store 277 Joules at 2.5 volts. This is not a great amount of energy storage, hence the limited discharge time. However, it can deliver more peak current than a lead-acid battery of the same size, and it recharges easily more than 500,000 times. The cost compares favorably with other D-size rechargeable batteries, but the cost per Watt-hour is not too good, $195.
