This dataset focuses on analyzing the impact of phosphoric acid additive content in electrolyte on the capacity of lead-acid batteries, revealing the quantitative relationship between phosphate-modified electrolyte and battery performance optimization. It provides key basis for electrolyte formula improvement for the company (as a battery manufacturer) and external relevant parties, with important application value, which is specifically reflected in the following aspects:
1. Optimizing electrolyte modified formula design: The company can accurately control the additive ratio by analyzing the impact of phosphoric acid content on battery capacity, inhibiting positive grid corrosion while improving negative plate sulfation, thereby significantly enhancing the deep cycle life and charge retention capability of the battery.
2. Promoting the development of high-performance battery technology: This dataset can provide references for electrolyte additive suppliers, battery R&D institutions and standard-setting organizations, supporting their work such as developing new composite additives, designing long-life batteries, formulating industry test specifications, etc., and promoting performance breakthroughs of lead-acid batteries in fields such as energy storage and backup power.

1. Data Collection:
Real-time recording of capacity test data for lead-acid batteries under different phosphoric acid additive contents, including fields such as test sample number, test time, phosphoric acid content (g/L), 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 phosphoric acid 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 influence of unit change in phosphoric acid content on battery capacity, and the intercept b represents the battery capacity value of lead-acid batteries under the baseline phosphoric acid content.
4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average battery capacity| × 100%.
(2) If k ≥ 8%, it is judged as "high impact"; if 4% ≤ k < 8%, it is judged as "medium impact"; if k < 4%, it is judged as "low impact".
