Abstract: A gelable system is formed by mixing lithium salts and small-molecule ether compounds such as cyclic ether compounds or straight-chain ether compounds, optionally added with inorganic nanoparticles, additives, other solvents and/or electrolytes; a gel system or solid system is formed by interaction between them (such as the formation of new complexes or self-assembly, etc.), and by ring-opening polymerization or polycondensation of the small-molecule cyclic ether compounds, or by addition-fragmentation chain transfer polymerization of the small-molecule straight-chain ether compounds, etc. The gel system or solid system not only has better safety in use than common gel systems or solid systems, but also better adjustability of strength. The strength of the formed gel can be improved from the source by changing composition and type of raw materials. The improvement in the strength enables the gel system to be expanded into the solid system, thereby further extending the application range of the gel system.

Abstract: A flexible all-solid-state lithium-ion secondary battery is prepared by placing a positive electrode and a negative electrode or optionally a separator of the lithium-ion secondary battery in a gelable system in which a solid electrolyte has not yet formed by a way of infiltration or coating, so that the surfaces and the interiors of the positive and negative electrodes are infiltrated by the gelable system, which also fills the voids inside the positive and negative electrodes. When the gelable system is solidified to form the solid electrolyte, it can form the solid electrolyte in situ on the surfaces and interiors of the positive and negative electrodes. The lithium-ion secondary battery prepared by the method can form a conductive network inside the entire battery, which can not only extremely reduce the internal resistance of the lithium-ion secondary battery, thereby improving the conductivity and rate capability, but also solve the potential safety hazard problem caused by liquid electrolytes.

Abstract: The present disclosure provides a power supply module and a power supply system. The power supply module is used as a first power supply module in a computing system which further includes a second power supply module. The first power supply module and the second power supply module are cascaded in sequence.
