Patent number: 11352445Abstract: Methods for preparing a recombinant protein from a bacterium are provided. The method includes constructing an expression vector including two promoters. Each of the two promoters attaches a secretion signal peptide to one polypeptide of a protein. The protein attached with the two promoters and secretion signal peptides is then cloned into the expression vector to provide a recombinant expression plasmid. The recombinant expression plasmid is transformed into a host cell. A fermentation process is performed to grow the host cell and to induce an expression to synthesize polypeptides in the host cell and to transport the polypeptides to an outside of a cytoplasm of the host cell, such that the polypeptides are released in a soluble form in a growth medium of the host cell. The polypeptides are assembled into a three-dimensional structure of the protein. The protein is captured from the growth medium.Type: GrantFiled: December 31, 2018Date of Patent: June 7, 2022Assignee: JECHO LABORATORIES INC.Inventors: Jianwei Zhu, Cedric Cagliero, Andrew Burnette, Yueqing Xie, Hua Jiang, Huili Lu, Manyu Luo

Patent number: 11239498Abstract: The present disclosure relates to the technical field of lithium-ion battery, and particularly, to an electrolytic solution and a lithium-ion battery including the electrolytic solution. The electrolytic solution includes additives, and the additives include an additive A and an additive B. The additive A forms a film on the surface of the positive electrode and effectively prevents interface side reactions at the positive electrode. Comparing with the additive A, the additive B is preferentially reduced to form a film at the negative electrode, avoiding an increase in impedance and deterioration of cycling dynamic performance, etc., caused by film formation of the additive A on the negative electrode. The combination of the additive A and additive B imparts the battery with a reduced gas production, a higher capacity retention rate and a lower impedance at high temperature.Type: GrantFiled: April 22, 2019Date of Patent: February 1, 2022Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Jianwei Zhu, Chenghua Fu, Xiaomei Wang
