This dataset focuses on analyzing the correlation between the proportion of positive electrode β-PbO₂ and the charging efficiency of lead-acid batteries, revealing the quantitative relationship between the crystal structure of positive electrode active materials and the battery's charging performance. It provides important process optimization basis for the company (as a battery manufacturer) and external relevant stakeholders, with significant application value, which is specifically reflected in the following aspects:
1. Optimizing positive electrode material preparation process: The company can accurately regulate the formation process parameters of positive electrode grids (such as current density, temperature, electrolyte concentration, etc.) by analyzing the correlation between β-PbO₂ proportion and charging efficiency, increase the generation proportion of β-PbO₂, thereby significantly improving the battery's charging acceptance and energy conversion efficiency.
2. Guiding the R&D of new positive electrode materials: This dataset can provide scientific basis for positive electrode material R&D institutions, battery manufacturing enterprises and industry standard-setting departments, supporting their work in positive electrode material modification, new additive development, charging process optimization and performance evaluation standard formulation, etc., promoting the innovative development of lead-acid battery positive electrode material technology.

1. Data collection:
Real-time recording of charging efficiency test data of lead-acid batteries under different positive electrode β-PbO₂ proportions, including fields such as test sample number, test time, β-PbO₂ proportion (%), charging efficiency (%), etc.
2. Data preprocessing:
(1) Perform denoising processing on the collected data to ensure data accuracy.
(2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the charging efficiency field in dataset X.
3. Calculation of correlation coefficient:
(1) Based on dataset X (taking β-PbO₂ proportion as the independent variable and charging efficiency as the dependent variable), use the CORREL function to calculate the correlation coefficient r between β-PbO₂ proportion and charging efficiency.
(2) The value range of correlation coefficient r is [-1, 1]. The closer its absolute value is to 1, the stronger the correlation between the two; the closer its absolute value is to 0, the weaker the correlation between the two.
4. Result application:
If |r| ≥ 0.8, it is judged as "strong correlation"; if 0.5 ≤ |r| < 0.8, it is judged as "moderate correlation"; if |r| < 0.5, it is judged as "weak correlation".
