Patent number: 11508956Abstract: A method of manufacturing a free-standing electrode film includes preparing a mixture including an electrode active material, a binder, and an additive solution or conductive paste, the additive solution or conductive paste being in an amount less than 5% by weight of the mixture and including a polymer additive and a liquid carrier, as well as a conductive material in the case of a conductive paste. The mixture may have total solid contents greater than 95% by weight. Preparing the mixture may include mixing the additive solution or conductive paste with the electrode active material to lubricate the electrode active material and subsequently adding and mixing in the binder. The method may further include subjecting the mixture to a shear force and, after the mixture has been subjected to the shear force, pressing the mixture into a free-standing film.Type: GrantFiled: September 8, 2020Date of Patent: November 22, 2022Assignee: LiCap Technologies, Inc.Inventors: Linda Zhong, Erika Shaw, Bae Kyun Kim

Accelerated formation of intercalation compounds within capacitor or battery cell negative electrode
Patent number: 11367861Abstract: A manufacturing method for the formation of lithium, potassium, and/or calcium intercalation compounds on a negative electrode for a battery or capacitor cell is disclosed. The battery or capacitor cell is constructed with a negative electrode that may contain graphitic carbon, silicon, metal oxide, and/or complex metal oxides and a lithium, potassium, and/or calcium ion source supplemental electrode. After construction of the cell, a method of controlled electrical contact is applied between the positive electrode and negative electrode to accelerate and regulate a process of ion exchange between the supplemental metal ion source electrode and the negative electrode which results in the formation of intercalation compounds within the negative electrode, and produces a battery or capacitor with a higher working voltage, high cycle life, and long DC life.Type: GrantFiled: April 8, 2020Date of Patent: June 21, 2022Assignee: LiCap Technologies, Inc.Inventor: Jonathan Hart -
