ELECTRODE FOR LITHIUM SECONDARY BATTERY, LITHIUM SECONDARY BATTERY USING THE SAME AND FABRICATION METHOD THEREOF

摘要

Provided in the present invention are an electrode for a lithium secondary battery, a lithium secondary battery using the same, and a manufacturing method thereof. The electrode for a lithium secondary battery includes: a collector body; an electrode active material layer positioned on top of the collector body; and inorganic particles dispersed in the electrode active material layer and have more than two radical polymerizing functional groups. According to the said invention, when forming a macromolecular electrolyte caused by an in-situ polymerization, a direct polymerization reaction between monomers and inorganic particles inside a precursor solution can and be led to an enhancement in the interfacial property between the electrode and electrolyte. Moreover, macromolecular electrolyte distribution inside the electrode can be made uniform. Therefore, the lithium secondary battery can have an improved lifespan and a high discharge during a charging and discharging process.
