Synthetic data for Li-ion Batteries Degradation Maps with degradation example
收藏资源简介:
This dataset contains the data associated with the publication "Best Practices for Incremental Capacity Analysis" in Frontiers in Energy Research. It consists of synthetic data for the main Li-ion chemistries for different degradations. Available chemistries: GIC/NMC111 GIC/NMC532 GIC/LCO GIC/NCA GIC/LMO GIC/(NMC,LMO) GIC/LFP (GIC/Si)/NMC811 LTO/NMC LTO/LMO LTO/(NCA/LCO) Map files contains data for up to 30% of each degradation mode individually (or 500% for kinetic and resistance variations) at C/25 in charge and discharge. The variable Mapindex summarizes the order for the data in the Params and Voltage variables (Vmc and Vmd, for charge and discharge respectively). The variable Params summarizes the simulation parameters (column index in Paramindex). Qmc and Qmd contains the capacity values in charge and discharge respectively. Example files contains data for up to 15% LLI, 10%LAMPE, and 10%LAMNE C/25 simulations in charge and discharge with 3 % increments (for LLI) and 2% increments (for LAMs). The variable Params summarizes the simulation parameters (column index in Paramindex). Qc and Qd contains the capacity values in charge and discharge respectively and Vc, and Vd the voltage response. All simulations were performed with the 2022 version of the alawa toolbox using stock electrode data. Voltage and kinetics of electrodes from different manufacturers, with different composition, or with different architecture might differ significantly.
本数据集关联发表于《Frontiers in Energy Research》的论文《Best Practices for Incremental Capacity Analysis》(增量容量分析最佳实践),包含针对不同退化场景下主流锂离子电池(Li-ion)化学体系的合成数据。可用电池化学体系包括:GIC/NMC111、GIC/NMC532、GIC/LCO、GIC/NCA、GIC/LMO、GIC/(NMC,LMO)、GIC/LFP、(GIC/Si)/NMC811、LTO/NMC、LTO/LMO、LTO/(NCA/LCO)。 Map文件存储了以C/25倍率进行充放电时的数据,涵盖各退化模式单独占比最高达30%(动力学与内阻变化项最高可达500%)的场景。变量Mapindex用于概括Params与Voltage变量(充放电分别对应Vmc与Vmd)中的数据排序规则;变量Params用于概括仿真参数(对应Paramindex中的列索引)。Qmc与Qmd分别存储充放电过程中的容量数值。 Example文件包含以C/25倍率进行充放电的仿真数据,对应参数为锂存量损失(LLI)达15%、正极活性物质损失(LAMPE)达10%、负极活性物质损失(LAMNE)达10%,其中LLI的增量步长为3%,LAMs的增量步长为2%。变量Params用于概括仿真参数(对应Paramindex中的列索引);Qc与Qd分别存储充放电过程中的容量数值,Vc与Vd则对应电压响应数据。 所有仿真均采用2022版alawa工具箱,基于标准电极数据完成。不同制造商、不同配方或不同结构的电极,其电压特性与动力学行为可能存在显著差异。
