SLURRY OBTAINED USING BINDER FOR BATTERY ELECTRODES, ELECTRODE OBTAINED USING THE SLURRY, AND LITHIUM ION SECONDARY BATTERY OBTAINED USING THE ELECTRODE

摘要

Provided is a slurry for lithium ion secondary battery electrodes, which has proper binding properties between active materials and between an active material and a current collector, an electrode using the slurry, and a lithium ion secondary battery using the electrode and having both a high initial discharge capacity and an excellent charge-discharge high-temperature cycle characteristic. The present invention relates to a slurry for lithium ion secondary battery electrodes, which is obtained using a binder for battery electrodes and an active material and has a pH of 3.0 to 6.0. Preferably, the slurry contains a binder for battery electrodes in an amount of 0.2 to 4.0% by mass based on the active material.
