Abstract
The present invention provides a method for measuring a distribution of pores in an electrode for a secondary battery, which can easily measure a distribution of pores inside the electrode for a secondary battery.
Claims8
A method for measuring a distribution of pores in an electrode for a secondary battery, comprising:
- preparing an electrode for a secondary battery comprising an electrode active material, a binder, and a conductive material;
- filling pores inside the electrode for a secondary battery with a polymer comprising silicon by impregnating the polymer comprising silicon into the electrode for a secondary battery;
- producing an electrode cross-sectional sample by irradiating the electrode for a secondary battery with an ion beam of an ion milling device;
- detecting silicon present on the electrode cross-sectional sample by using an energy-dispersive X-ray spectroscopy;
- and
- confirming a distribution of pores by analyzing an image in which points of silicon detected by the energy-dispersive X-ray spectroscopy are mapped.
