Very low profile - batteries resembling the
profile of a credit card are feasible: cell thickness measuring as
little as one millimeter.
Flexible form factor - manufacturers are not
bound by standard cell formats. With high volume, any reasonable
size can be produced economically. Lightweight - gelled electrolytes
enable simplified packaging by eliminating the metal
shell.
Improved safety - more resistant
to overcharge; less chance for electrolyte leakage.
