Patent number: 11614491Abstract: System, methods, and other embodiments described herein relate to improving the cycling of batteries by using data and a hierarchical Bayesian model (HBM) for predicting the cycle life of a cycling protocol. In one embodiment, a method includes classifying cycle life of a battery into a class using battery data from cycling with a protocol, wherein the class represents cycle life distributions of cycling protocols. The method also includes quantifying, using the class in a HBM, variability for the battery induced by the protocol. The method also includes predicting, using the HBM, an adjusted cycle life for the protocol according to the variability. The method also includes communicating the adjusted cycle life to operate the battery.Type: GrantFiled: April 20, 2021Date of Patent: March 28, 2023Assignees: Toyota Research Institute, Inc., Massachusetts Institute of Technology, The Board of Trustees of the Leland Stanford Junior UniversityInventors: Richard Dean Braatz, Benben Jiang, Fabian Mohr, Michael Forsuelo, William E.

Patent number: 9130231Abstract: In a lithium ion battery, one or more chelating agents may be attached to a microporous polymer separator for placement between a negative electrode and a positive electrode or to a polymer binder material used to construct the negative electrode, the positive electrode, or both. The chelating agents may comprise, for example, at least one of a crown ether, a crown ether, a podand, a lariat ether, a calixarene, a calixcrown, or mixtures thereof. The chelating agents can help improve the useful life of the lithium ion battery by complexing with unwanted metal cations that may become present in the battery's electrolyte solution while, at the same time, not significantly interfering with the movement of lithium ions between the negative and positive electrodes.Type: GrantFiled: July 21, 2014Date of Patent: September 8, 2015Assignee: GM Global Technology Operations LLCInventors: Ion C.
