Patent number: 9761861Abstract: The present invention is directed to battery system and operation thereof. In an embodiment, lithium material is plated onto the anode region of a lithium secondary battery cell by a pulsed current. The pulse current may have both positive and negative polarity. One of the polarities causes lithium material to plate onto the anode region, and the opposite polarity causes lithium dendrites to be removed. There are other embodiments as well.Type: GrantFiled: May 28, 2014Date of Patent: September 12, 2017Assignee: QuantumScape CorporationInventors: Timothy Holme, Marie Mayer, Ghyrn Loveness, Zhebo Chen, Rainer Fasching

Publication number: 20160013483Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.Type: ApplicationFiled: September 18, 2015Publication date: January 14, 2016Inventors: Ghyrn E. Loveness, William S. Delhagen, Rainer Fasching, Song Han, Zuqin Liu
