Patent number: 11962015Abstract: Provided are an electrolytic copper foil, an electrode and a lithium-ion cell comprising the same. The electrolytic copper foil has a first surface and a second surface opposite the first surface. An absolute difference of the FWHM of the characteristic peaks of (111) planes of the first surface and the second surface analyzed by GIXRD is less than 0.14, the first and the second surfaces each have a nanoindentation hardness of 0.3 GPa to 3.0 GPa, and the yield strength of the electrolytic copper foil is more than 230 MPa. By controlling the absolute difference of the FWHM of the characteristic peaks of (111) plane of these two surfaces, the nanoindentation hardness of these two surfaces and the yield strength, the electrolytic copper foil can have improved tolerance to the repeated charging and discharging and reduced warpage, thereby improving the yield rate and value of the lithium-ion cell.Type: GrantFiled: September 8, 2022Date of Patent: April 16, 2024Assignee: CHANG CHUN PETROCHEMICAL CO., LTD.Inventors: Ting-Mu Chuang, Sung-Shiuan Lin, Yao-Sheng Lai, Jui-Chang Chou

Patent number: 11296605Abstract: A synchronous rectifier controller controls a rectification power switch connected in series with a secondary winding between two power lines. The synchronous rectifier has a gate driver and a slew-rate detector. The gate driver drives the rectification power switch. The slew-rate detector detects a channel voltage of the rectification power switch, checks if a slew rate of the channel voltage exceeds a slope threshold. If the slew rate exceeds the slope threshold, the slew-rate detector turns the rectification power switch ON through the gate driver. If the slew rate is less than the slope threshold, the slew-rate detector reduces the slope threshold.Type: GrantFiled: May 13, 2020Date of Patent: April 5, 2022Inventors: Chih-Chiao Tsai, Jui-Chang Chuang
