Abstract — To date, lithium-ion batteries have become one of the most important energy storage devices. Creating lithium ion microbatteries using materials structured at the nanoscale allow you to create solid-state lithium-ion batteries that have the fastest electrodes. In this work, we propose the design of an element of a lithium-ion current source, which has a 10 times higher stored energy density than similar devices that are widely used at present. The developed electrochemical cell has a fully solid-state design. The active material of the anode is silicene, a solid-state electrolyte is used, the cathode is made of complex transition metal oxides, and an ultra-thin insulating pad is used. The presented element of the secondary lithium-ion battery has a theoretical capacity of 3500 mAh g−1 and a high charging speed. The electrochemical cell is characterized by small size, low cost of components and operational safety.
