Abstract
An electrode active material composition containing a pyrolytic plasticizer, a polymer electrolytic matrix composition and a preparation method of a lithium ion polymer battery using the same are provided. Since a separate plasticizer extraction step using an organic solvent is not necessary, the preparation cost is reduced and the preparation process can be kept clean. In particular, since a uniform porosity plate can be fabricated after removing the plasticizer, a lithium ion polymer battery with improved high-rate charge and discharge characteristics can be prepared.
