How then is the current Li-polymer battery made conductive at ambient temperatures? Most of the commercial Li-polymer batteries or mobile phones are a hybrid. Some gelled electrolyte has been added to the dry polymer. The correct term for this system is Lithium Ion Polymer. For marketing reasons, most battery manufacturers call it simply Li-polymer. Since the hybrid lithium polymer is the only functioning polymer battery for portable use today, we will focus on this chemistry variation but use the correct term of lithium ion polymer (Li-ion polymer).
With gelled electrolyte added, what then is the difference between Li-ion and Li-ion polymer? Although the characteristics and performance of the two systems are very similar, the Li-ion polymer is unique in that the solid electrolyte replaces the porous separator. The gelled electrolyte is simply added to enhance ion conductivity.
Technical difficulties and delays in volume manufacturing have deferred the introduction of the Li-ion polymer battery. In addition, the promised superiority of the Li-ion polymer has not yet been realized. No improvements in capacity gains are achieved — in fact, the capacity is slightly less than that of the standard Li-ion battery. For the present, there is no cost advantage in using the Li-ion polymer battery. The major reason for switching to the Li-ion polymer is form factor. It allows wafer-thin geometries, a style that is demanded by the highly competitive mobile phone industry.summarizes the advantages and limitations of the Li-ion polymer battery.
