Abstract: A lipid delivery system, a virus-like structure (VLS) vaccine constructed therefrom, and a lipid particle capable of encapsulating an mRNA molecule encoding a SARS-CoV-2-specific antigen are provided. After the lipid particle encapsulates an mRNA molecule encoding a SARS-CoV-2 antigen, a SARS-CoV-2 S1 antigen protein can be embedded on a surface of an envelope structure of the lipid under specific buffer conditions to produce a VLS vaccine with an antigen-encoding mRNA molecule encapsulated inside and an outer membrane presenting a required viral antigen protein. The vaccine has a superior specific antibody-inducing ability to a SARS-CoV-2 mRNA vaccine and a polypeptide vaccine, can maintain a long-lasting high antibody level, and can also exhibit excellent immune binding abilities for the emerging different variants.

Abstract: This invention is related to a process for preparing polymeric Li-ion cell with high-capacity as well as the cells manufactured with the process. The process produces anode paste with lithium salt and cobalt oxide and sprays the paste onto aluminum current collector to form the anode; produces cathode paste with two lithium-embedded carbon materials and sprays the paste to copper current collector to form the cathode; produces a paste with polyvinylidene fluoride, silicon dioxide (gas phase), o-dibutyl phthalate ester, and acetone and sprays the paste onto a polyester film to form the diaphragm; performs extraction for the cell assembled with said anode, diaphragm, and cathode, welds lugs, immerses the cell into electrolyte to, and packs the cell with aluminum-plastic composite film, and finally performs formation for the cell, so that a polymeric Li-ion cell with high-capacity is accomplished.
