SILICON SECONDARY BATTERY

The present inventions relates to a silicon secondary battery and, more specifically, to a solid silicon secondary battery having a solid electrolyte and a method for preparing same. The present inventions, by means of substitutions of silicon for lithium of a secondary battery, enables decreasing of preparations cost and minimizing of environmental pollutions during discarding of the secondary battery. In additions, by means of laminate pressing multiple times a positive or negative electrode material and preparing a positive or negative electrode active material, the present inventions enables increasing of the density of a positive or negative electrode active material, thereby increasing current density and capacity. In additions, by having mesh plates equipped inside the positive electrode active material and the negative electrode active material, the present inventions enables effective moving of electrons. Moreover, by enabling common use of an electrode, of a silicon secondary battery, connected during a serial connections of the silicon secondary battery, the present inventions enables decreasing of the thickness of a silicon secondary battery assembly and increasing of output voltage. Also, by being integrally formed with a PCB or a chip and supplying a power source, the present inventions plays the role of a backup power source for instant discharging.
