“…This pathway can apply for either electrode, but loss of active material from the negative electrode is more likely to be a hidden trajectory since this electrode is typically oversized relative to the positive electrode; the exception is cells with lithium titanate electrodes, in which the positive electrode is limiting and can cause a "hidden" knee. 87,88 A richer picture emerges in models that capture the shifts in electrode stoichiometry with cycling. Lin et al 26 and Kindermann et al 90 89 Initially, all variables (LLI, LAM ne , and LAM pe ) increase linearly with cycle number.…”

Lithium-ion batteries can last many years but sometimes exhibit rapid, nonlinear degradation that severely limits battery lifetime. In this work, we review prior work on "knees" in lithium-ion battery aging trajectories. We first review definitions for knees and three classes of "internal state trajectories" (termed snowball, hidden, and threshold trajectories) that can cause a knee. We then discuss six knee "pathways", including lithium plating, electrode saturation, resistance growth, electrolyte and additive depletion, percolation-limited connectivity, and mechanical deformation-some of which have internal state trajectories with signals that are electrochemically undetectable. We also identify key design and usage sensitivities for knees. Finally, we discuss challenges and opportunities for knee modeling and prediction. Our findings illustrate the complexity and subtlety of lithium-ion battery degradation and can aid both academic and industrial efforts to improve battery lifetime.

“…In order to test the performance of the proposed model, it needs to be validated and compared to another known measured C loss during cycling and Calendar Aging. For the Cycling Aging, the input data needed for the C loss algorithm is extracted from (Baure & Dubarry, 2020), and the output is compared to the C loss from the same reference. Table 1 and Table 2 first columns show a summary of the extracted data that is required for the Cycling Aging C loss .…”

This research paper discusses the application of multiagent simulation model of production processes by reference to milk receiving and storage. The paper describes basic parameters for general models, and presents the experiment results obtained during the model processing, as well as the approach towards implementation of the multiagent system employing AnyLogic simulation environment. The introduction of general technique to plot multiagent simulation models allows to use digital tools to create a virtual copy of the true-life processes with the possibility to provide forecast and identification of the food production industries. The employment of simulation modeling enables refinement of the production process under study, identification of its weaknesses, and provision of the expert opinion on improvement of production processes and as regards the results of virtual testing thereof.

“…At the system level, Karouia et al [29] compared Li-ion and a ZEBRA-based BESS of different sizes from 0.1 to 5 KW, and Kubiak et al [30] analyzed the calendar aging induced degradation on a 250 kW/500 kWh system. At the cell level, and in addition to our previous work [31][32][33], Benato et al [34] tested cells of different chemistries under realistic conditions, and Li et al [35] tested nickel cobalt manganese cells for stationary applications. Finally, Podias et al, White et al, Elliot et al as well as Zhang et al investigated grid usage of recycled EV or bus batteries [36][37][38][39].…”

“…The Hawai'i Natural Energy Institute (HNEI) at the University of Hawai'i at Mānoa has been working on assessing the benefits of grid-scale BESS for the past decade [23,[31][32][33][40][41][42]. One of our demonstration BESS is installed on the Hawaii Electric Light Company power grid on northern tip of the Big Island of Hawai'i (star on the left of Figure 1) at the point of common coupling (PCC) between the 10.6 MW Hawaii Renewable Development Windfarm and the Waimea substation.…”

Grid-tied energy storage will play a key role in the reduction of carbon emissions. Systems based on Li-ion batteries could be good candidates for the task, especially those using lithium titanate negative electrodes. In this work, we will present the study of seven years of usage of a lithium titanate-based battery energy storage system on an isolated island grid. We will show that, even after seven years, the modules’ capacity loss is below 10% and that overall the battery is still performing within specifications. From our results, we established a forecast based on the internal degradation mechanisms of the hottest and coldest modules to show that the battery full lifetime on the grid should easily exceed 15 years. We also identified some inaccuracies in the online capacity estimation methodology which complicates the monitoring of the system.
