This dataset focuses on analyzing the impact of chloride ion impurity content in electrolytes on the capacity of lead-acid batteries, revealing the quantitative relationship between halide ion contamination and battery performance degradation. It provides a critical basis for electrolyte purity control for the company (as a battery manufacturer) and external relevant stakeholders, holding significant application value, which is reflected in the following aspects:
1. Strengthening the electrolyte quality control system: The company can establish strict deionized water standards and electrolyte impurity management plans by analyzing the impact of chloride ion content on battery capacity, effectively inhibiting plate corrosion and dendrite growth, thereby significantly improving the cycle stability and high-temperature performance of lead-acid batteries.
2. Guiding battery maintenance and recycling: This dataset can provide references for water treatment equipment suppliers, battery recycling enterprises and testing institutions, supporting their work such as optimizing pure water preparation processes, conducting pollution assessment of scrapped batteries, and developing purification technologies for regenerated electrolytes, and promoting the establishment of a more comprehensive environmental protection quality control system in the lead-acid battery industry.
1. Data collection:
Real-time recording of lead-acid battery capacity test data under different chloride ion contents, including fields such as test sample number, test time, chloride ion content (ppm), battery capacity/Ah, etc.
2. Data preprocessing:
(1) Denoise the collected data to ensure data accuracy.
(2) Aggregate the historically collected data (including this batch of collected data) to form dataset X, and calculate 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 chloride 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 a unit change in chloride ion content on battery capacity, and the intercept b represents the capacity value of lead-acid batteries under the reference chloride ion content.
4. Result application:
(1) Calculate the proportional coefficient k: k = |a / average battery capacity| × 100%.
(2) If k ≥ 12%, it is judged as "high impact"; if 6% ≤ k < 12%, it is judged as "medium impact"; if k < 6%, it is judged as "low impact".
