Yg. Lee et al., Lithium sulfonated styrene oligomer (LiSSO) as a new class of lithium saltfor polymer electrolytes, POLYM BULL, 47(2), 2001, pp. 167-174
A new class of lithium salt with single-ionic characteristics, lithium sulf
onated styrene oligomer (LiSSO) [(CH2CHC6H5)(7)-(CH2CHC6H4SO3-Li+)(2)], was
synthesized and its complex with poly(ethylene oxide) (PEO) was prepared.
The maximum ionic conductivity of the PEO/LiSSO complex at 65 degreesC was
2.1 x 10(-4) S/cm at a salt concentration of [Li+]/[EO] = 0.20. The lithium
cationic transference number (t(+)) of the PEO/LiSSO complex was found to
be 0.95, and the polymer electrolyte was electrochemically stable up to 6.2
