Title:
SILICON CATALYST BATTERY AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014182870
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a silicon catalyst battery and a manufacturing method thereof which can solve the following problems of lithium used in conventional lithium ion secondary batteries: the resource of lithium is unevenly distributed and lithium is in danger of causing a fire and corrosion; and it has been demanded to multiply an energy density.SOLUTION: A silicon catalyst battery is used as a secondary battery. The silicon catalyst battery comprises: a positive electrode including carbon capable of oxidizing and reducing oxygen in air; a negative electrode composed of a metal electrode; a layer of electrolyte; a separator interposed therebetween; and a current collecting electrode. The positive electrode has thereinside: carbon microparticles of graphite or the like; silicon microparticles; a positive electrode catalyst such as titanium or manganese dioxide; and an auxiliary material such as alginic acid or citric acid which serves as a stabilizer for the silicon microparticles. Outside the positive electrode, the silicon catalyst battery has the current collecting electrode having small holes for natural circulation of air, and a surface-processed film made of isoprene or the like through which water never permeates. The electrolyte includes: a metal chloride solution; and as an electrolytic solution, a metal ethoxide additive agent consisting of an ether-based solvent with a metal bromide added thereto.
