The growing interest in battery systems has led to major advances in h
igh-energy and/or high-power density lithium batteries. Potential appl
ications for lithium batteries include radio transceivers, portable el
ectronic instrumentation, emergency locator transmitters, night vision
devices, human implantable devices, as well as uses in the aerospace
and defense programs. With this new technology comes the use of new so
lvent and electrolyte systems in the research, development, and produc
tion of lithium batteries. The goal is to enhance lithium battery tech
nology with the use of non-hazardous materials. Therefore, the toxicit
y and health hazards associated with exposure to the solvents and elec
trolytes used in current lithium battery research and development is e
valuated and described.
