Scientists in Ulm, Germany, say the new lithium-ion cells they are developing can retain 85% of their capacity after 10,000 charge cycles.
Researchers at ZSW (short for Center for Solar Energy and Hydrogen Research Baden-Wurttemberg) also say their small experimental cells have a power density of 1,100 watts per kilogram. That's nearly three times the density of some lithium-ion batteries currently in use.
The ability to maintain most of their capacity after 10,000 charge cycles implies that a battery made of the new cells could provide a service life of about 25 years considerably greater than is likely from lithium-ion batteries in use today.
The ZSW team offers no details about the architecture of its cells. But it says it has been able to produce them "semi-automatically" in the lab. The researchers say they are looking for industrial partners to help develop large prismatic lithium cells, a precursor to building a battery.
