Abstract

Porous carbons are the active materials of choice for supercapacitor applications because of their power capability, long-term cycle stability, and wide operating temperatures. However, the development of carbon active materials with improved physicochemical and electrochemical properties is generally carried out via time-consuming and cost-ineffective experimental processes. In this regard, machine-learning technology provides a data-driven approach to examine previously reported research works to find the critical features for developing ideal carbon materials for supercapacitors. Here, we report the design of a machine-learning-derived activation strategy that uses sodium amide and cross-linked polymer precursors to synthesize highly porous carbons (i.e., with specific surface areas > 4000 m2/g). Tuning the pore size and oxygen content of the carbonaceous materials, we report a highly porous carbon-base electrode with 0.7 mg/cm2 of electrode mass loading that exhibits a high specific capacitance of 610 F/g in 1 M H2SO4. This result approaches the specific capacitance of a porous carbon electrode predicted by the machine learning approach. We also investigate the charge storage mechanism and electrolyte transport properties via step potential electrochemical spectroscopy and quasielastic neutron scattering measurements.

Abstract

Li-ion batteries will lose both capacity and power over time due to calendar aging caused by slow parasitic processes that consume Li+ ions. Studying and mitigating these processes is traditionally an equally slow venture, which is especially taxing for the validation of new active materials and electrolyte additives. Here, we evaluate whether potentiostatic holds can be used to accelerate the diagnosis of Li+ loss during calendar aging. The technique is based on the idea that, under the right conditions, the current measured as the cell voltage is held constant can be correlated with the instantaneous rate of side reactions. Thus, in principle, these measurements could capture the rate of capacity fade in real time. In practice, we show that this method is incapable of quantitatively forecasting calendar aging trends. Instead, our study demonstrates that potentiostatic holds can be applied for initial qualitative screening of systems that exhibit promising long-term stability, which can be useful to shrink the parameter space for calendar aging studies. By facilitating the identification of improved formulations, this approach can help accelerate innovation in the battery industry.

Abstract

Rainstorm and the induced flood disaster often cause serious damage to transportation system, resulting in the loss of life and property. To improve the resilience of transportation system, this study proposes a framework for assessing the impacts of rainstorm and flood disaster on road network based on GPS data. The change ratio of traffic flow and congestion index are used to evaluate the disrupted and detour road sections caused by rainstorm. A method based on the change of traffic flow compared to the normal circumstances is proposed to identify the flood-damaged road sections. A case study in Beijing verifies the feasibility and practicality of the proposed framework, which can effectively assess the impacts of rainstorm from multiple spatial and temporal dimensions, identify the flood-damaged road sections, and supplement existing research. Research findings can provide scientific basis for the emergency management departments to accurately identify the roads affected by rainstorm and improve the resilience of transportation system., Author(s): Zhenzhen Yang (corresponding author) [1] 1. Introduction With the increasing severity of global warming, rainstorm and the induced flood disaster occur more and more frequently, which affects the normal [...]
