Ji. Yamaki et al., SAFETY EVALUATION OF RECHARGEABLE CELLS WITH LITHIUM METAL ANODES ANDAMORPHOUS V2O5 CATHODES, Journal of Applied Electrochemistry, 28(2), 1998, pp. 135-140
Rechargeable cells with lithium metal anodes have a very large theoret
ical energy density and are a promising cell system. However, recharge
able lithium metal cells are not yet currently commercially available.
One of the biggest problems with the cells is the poor safety aspect
resulting from the high chemical reactivity of lithium. We have been s
tudying a cell system consisting of an amorphous (a-)V2O5-P2O5 (95 : 5
in molar ratio) cathode, a lithium (Li) metal anode and an organic el
ectrolyte in fabricating an AA-size prototype. In this paper, we repor
t recent progress on our rechargeable lithium metal cell focusing on i
ts safety.
