ADA Technologies, Inc.
has completed research that demonstrates the technical feasibility of developing
advanced lithium-ion nano-batteries. Funded by the National Science Foundation,
the $150,000 Phase I research focused on developing high-capacity / high-rate
nano-structured electrodes that could be combined with environmentally benign
electrolytes to significantly improve lithium-ion battery performance. The improvement
in performance is due to the unique structures of nano-scale electrodes.
Lithium-ion batteries represent the current state-of-the-art technology for
rechargeable batteries. However, performance (energy / power densities, safety,
and cycle life) of currently available lithium-ion batteries is limited by electrode
and electrolyte properties.
"The Phase I research was completely successful. Laboratory test batteries
achieved excellent performance measures with the potential to achieve a two-fold
increase in energy density and a ten-fold increase in power density compared
to current state-of-the-art lithium-ion battery technology," said Wen Lu,
Ph.D., project principal investigator and ADA Technologies senior research scientist.
Improvements in electrodes and electrolytes are needed to develop advanced
lithium-ion batteries to satisfy increasing performance demands. Lithium-ion
batteries are used in a wide range of applications, including consumer electronics
(cell phones, laptops, pagers, camcorders), medical electronics (drug delivery
units, portable defibrillators, neurological stimulators), transportation technology
(electric vehicles, hybrid electric vehicles, plug-in hybrids), and military
and defense (communication devices, unmanned aerial vehicles, spacecraft probes,
ADA has received nearly $1 million in grant money for advanced energy storage
technology R&D, including the development of lithium-ion batteries and ultracapacitors.
