Title:
電極用複合粉末及びその製造方法
Document Type and Number:
Japanese Patent JP4264513
Kind Code:
B2
Abstract:

To provide a universal and simple means for attaining a high output of an electrode without reducing energy density per weight and energy density per volume of a battery and a capacitor.

The compound powder for electrode is formed by binding electrode activator through a conductive material. The compound powder for the electrode is characterized by being that (1) the content of the conductive material in the compound powder for electrode is 0.01-30 wt%, and that (2) the compound powder for electrode has such a bonding strength that the bonding of the electrode active material and the conductive material is not exfoliated on condition of putting 0.5 mg of the compound powder for electrode and 50 ml of water/ethanol mixed solution (volume ratio 1:1) in a 100ml beaker, and stirring the solution by a stirrer having a length of 3 cm and a diameter at the cross section of central part of 5 mm at 600 rpm for 5 minutes. The manufacturing method of the compound powder is also provided.
