Overview

Numerical optimization demonstrates that increasing fin count effectively reduces maximum temperatures in lithium-ion batteries, suggesting viable passive thermal management for high-discharge rates.

Key Points

Investigate the impact of fin geometric parameters—including diameter, thickness, and count—on passive cooling performance in cylindrical lithium-ion batteries at high discharge rates and identify optimal configurations.
Conducted numerical simulations of a cylindrical lithium-ion battery operating at a 5C discharge rate across varying fin diameters (20–36 mm), thicknesses (0.5–2 mm), and quantities (3–9 fins).
Applied the I-optimal algorithm via the Response Surface Method to evaluate trade-offs and optimize objective functions including maximum temperature, average temperature, temperature homogeneity, and total mass.
Increasing the number of fins from 3 to 9 reduced maximum battery temperature by 6.0% and temperature difference by 36.3%, showing greater thermal homogeneity improvement than increases in diameter or thickness.
Increasing fin diameter reduced maximum temperature by 3.4% but increased mass by 12.2%, while increasing thickness decreased maximum temperature by 2.2% but increased mass by 21%.
Multi-objective optimization established an optimal configuration of 32.4 mm diameter, 1.35 mm thickness, and 9 fins, maintaining battery operating temperature below 349 K.
