Contact UsIncreasing the size of cylindrical lithium-ion batteries (LIBs) to achieve higher energy densities and faster charging represents one effective tactics in nowadays battery society. A systematic understanding on the size effect of energy density, thermal and mechanical performance of cylindrical LIBs is of compelling need.
LIBs of greater diameter are prone to insider buckling and outer fracture. Increasing diameter is a trade-off between thermal and mechanical performance. Increasing the size of cylindrical lithium-ion batteries (LIBs) to achieve higher energy densities and faster charging represents one effective tactics in nowadays battery society.
The findings of this study show that the surface temperature of the cylinder lithium-ion battery can be lowered by adding fins and using phase change material. For protection, efficiency, price, and lifetime, it is essential to predict how lithium-ion batteries operate accurately.
SOC and SOH remain at 100% and 80%, utilizing an 8Ah battery with a nominal voltage of 4.2V, and a 3.9-year life expectancy, addressing charge/discharge cycle issues. Efficient heat dissipation in lithium-ion battery packs is crucial for safety, necessitating a thorough assessment of thermal performance during the design phase.
A systematic understanding on the size effect of energy density, thermal and mechanical performance of cylindrical LIBs is of compelling need. Taking the diameter D and height H of cylindrical LIBs as variables, we shed light on the energy densities, thermal and mechanical performance of cylindrical LIBs.
The thermal performance of cylindrical LIBs could be better characterized by the diameter-to-height ratio: cells of identical capacity but with greater D / H show lower temperature rise and lower thermal gradient at high cycling rates.
