This dataset focuses on analyzing the impact of iron ion impurity content in electrolytes on the capacity of lead-acid batteries, and reveals the quantitative relationship between metal ion contamination and battery performance degradation. It provides critical electrolyte quality control basis for the company (as a battery manufacturer) and external stakeholders, with significant application value, which is specifically reflected in the following aspects: 1. Enhancing electrolyte purification process control: The company can establish strict raw material testing standards and electrolyte purification procedures by analyzing the impact of iron ion content on battery capacity, effectively control the content of harmful impurities, thereby significantly reducing battery self-discharge rate and extending battery service life. 2. Improving battery failure analysis and maintenance standards: This dataset can provide references for battery recycling enterprises, testing and certification institutions and end users, supporting them in carrying out research on battery failure mechanisms, formulating maintenance specifications, evaluating the purity of recycled electrolytes and other work, and promoting the high-quality and sustainable development of the lead-acid battery industry. 1. Data Collection: Real-time recording of lead-acid battery capacity test data under different iron ion contents, including fields such as test sample number, test time, iron ion content (ppm), battery capacity / Ah, etc. 2. Data Preprocessing: (1) Denoising the collected data to ensure data accuracy. (2) Aggregating the historically collected data (including this collection) to form dataset X, and calculating the average value of the battery capacity field in dataset X. 3. Calculation of Linear Regression Slope a and Intercept b: (1) Based on dataset X (with iron ion content as the independent variable and battery capacity as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. (2) The slope a represents the degree of impact of unit iron ion content change on battery capacity, and the intercept b represents the capacity value of lead-acid batteries under the reference iron ion content. 4. Result Application: (1) Calculate the proportional coefficient k: k = |a / average battery capacity| × 100%. (2) If k ≥ 10%, it is classified as "High Impact"; if 5% ≤ k < 10%, it is classified as "Medium Impact"; if k < 5%, it is classified as "Low Impact".
