  • Publication number: 20220068420
    Abstract: An integrated circuit includes a test counting circuit, a test information storage circuit, a sequence control circuit and a driving circuit. The test counting circuit generates a counting address signal. The test information storage circuit stores a test control value and outputs the test control value based on the counting address signal. The sequence control circuit changes an output sequence of the test control value based on a sequence control signal and outputs a final test control value based on the test control value or a target control value. The driving circuit performs a pre-set test operation based on the final test control value.

  • Publication number: 20210098826
    Abstract: A lithium secondary battery including a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a sulfur dioxide-based inorganic electrolyte solution. The negative electrode includes a negative electrode active material which includes a carbon material having a coating comprising titanium oxide (TiOx, 0<x<2). The titanium oxide improves the wettability of the carbon material negative electrode to the inorganic electrolyte solution and the charge transfer reaction on the surface and minimizes the interfacial resistance of the carbon material/inorganic electrolyte solution, thereby improving the high-rate charge/discharge characteristics.
