Title:
リチウムイオン二次電池電極用バインダー組成物およびその利用
Document Type and Number:
Japanese Patent JP4389282
Kind Code:
B2
Abstract:
PURPOSE: A binder composition for a second battery of a lithium ion is provided to improve charge/discharge cycle property of a battery in a high temperature by latex composed of polymer particle, by polymerizing a particular monomer as an electrode binder composition. CONSTITUTION: A binder composition for a second battery of a lithium ion contains a structure unit of an ethylene unsaturated carvone acid ester monomer derive(a) and a structure unit of an ethylene unsaturated carvone acid monomer derive(b). The structure unit(a) divided by the structure unit(b) is equal with 99-60 divided by 1-40(weight rate). The binder composition for the second battery is composed of a polymer particle, which does not contain nitrile corresponded as sum of the both structure units(a,b) is over 80 percents to a whole unit.
