Patent number: 11929505Abstract: Methods are disclosed for manufacturing an electrode for use in a device such as a secondary battery. Electrodes may include a first layer having first active particles adhered together by a binder, a second layer having second active particles adhered together by a binder, and an interphase layer interposed between the first and second layers. In some examples, the interphase layer may include an interpenetration of the first and second particles, such that substantially discrete fingers of the first layer interlock with substantially discrete fingers of the second layer.Type: GrantFiled: December 28, 2021Date of Patent: March 12, 2024Assignee: EnPower, Inc.Inventors: Kjell William Schroder, Adrian Yao, Neelam Singh

Patent number: 11645056Abstract: Capturing dependencies between variables using a variable agnostic object is disclosed. A system is configured to obtain an indication of a first dependency of a first variable to a second variable via a programming interface and depict the first dependency, the first variable, and the second variable in a first instance of a variable agnostic object in a source code. The system is also configured to obtain an indication of a second dependency of a third variable to a fourth variable via the programming interface and depict the second dependency, the third variable, and the fourth variable in a second instance of the variable agnostic object in the source code. The system is also configured to compile the source code to generate a computer-executable program capturing the first dependency and the second dependency based on the first instance and the second instance of the variable agnostic object.Type: GrantFiled: July 15, 2021Date of Patent: May 9, 2023Assignee: Intuit Inc.Inventors: Samarinder Singh Thind, Rajat Khare, Neelam Singh, Suresh Krishna Devanathan, Deepak Radhakrishna

Publication number: 20230006190Abstract: An auxiliary electrode includes a conductive layer having a first major surface in an X-Y plane, the conductive layer is electrically conductive and has a first surface area. The auxiliary electrode includes a first carrier ion supply layer and a second carrier ion supply layer, each carrier ion supply layer comprising a material that supplies carrier ions for an electrode of the secondary battery. The first carrier ion supply layer covers a first region of the first major surface of the conductive layer and the second carrier ion supply layer covers a second region of the first major surface of the conductive layer. The first and second regions are separated by a third region, the third region configured to be folded such that the first region and the second region are substantially parallel, and the third region is substantially perpendicular to the first and second regions in the folded configuration.Type: ApplicationFiled: June 28, 2022Publication date: January 5, 2023Inventors: Aditya MANDALAM, Richard J.
