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.

Abstract: A lithium polymer battery is provided. The lithium polymer battery includes a positive electrode plate having a positive electrode current collector and a positive electrode sheet having a positive electrode active material fixed to at least one plane of the positive electrode current collector as a main component, a negative electrode plate having a negative electrode current collector and a negative electrode sheet having a negative electrode active material fixed to at least one plane of the negative electrode current collector as a main component, a separator interposed between the positive electrode plate and the negative electrode plate, for isolating the positive and negative electrode plates from each other, and coating means interposed between the positive electrode current collector and the positive electrode sheet and between the negative electrode current collector and the negative electrode sheet, for increasing the adhesiveness of the current collectors and the sheets.
