Description

Technical Field

[0001] The invention relates to the technical field of solid-state battery production, and in particular to a method for automatically adjusting peripheral welding tracks of a CCD in producing solid-state batteries. Background Art

[0002] Solid-state battery is a battery that uses solid electrodes and solid electrolytes. The negative electrode material of the solid-state battery can be a composite negative electrode of nano-silicon and graphite, and the positive electrode can be lithium manganese oxide, lithium-rich manganese-based materials or lithium-free positive electrode materials. The electrolyte is a solid electrolyte with an energy density of 300-450 watt-hours / kilogram. Solid-state batteries use solid electrolytes to replace the electrolytes and diaphragms of traditional lithium-ion batteries. They are safer, have higher energy density, and have stronger cycle performance. They have become the main research and development direction of the next generation of power batteries. Solid electrolytes can be roughly divided into three categories: inorganic electrolytes, solid polymer electrolytes, and composite electrolytes. Since the power-to-weight ratio of solid-state batteries is relatively high, they are ideal batteries for electric vehicles. CCD is a semiconductor device that can convert optical signals into analog current signals. After amplification and analog-to-digital conversion, it can achieve image acquisition, storage, transmission, processing and reproduction. It has the characteristics of small size and light weight, low power consumption, high sensitivity and fast response speed.
