The ability to fast charge automotive lithium ion batteries is key to enabling wide scale adoption by consumers. A primary challenge to fast charging is lithium plating due to insufficient lithium diffusion rates into the graphite anode. Plating and subsequent poor cycling of plated lithium leads to capacity loss over time, and possible failure due to dendrite-induced short circuit. Sandia National Laboratories and University of Michigan have worked together to develop advanced anode architectures, known as Highly Ordered Hierarchies (HOH), to increase lithium diffusion rates and avoid lithium plating. This work will describe Sandia's latest efforts to characterize and quantify the improvements brought on by these advanced anode structures. High precision cycling and isothermal control during fast charging allow very precise tracking of cycle-to-cycle efficiency and intra-cycle differential coulometry. These methods are used to detect and quantify lithium plating at the earliest stages, and provide a quantitative basis for evaluating the dependence of lithium plating on anode architecture, temperature, and current. We will describe the beneficial effects of HOH anode structures, as well as the beneficial effects of moderate temperature increases. A thorough discussion on experimental conditions will also be conducted, to aid others in performing similar measurements.
