Design and Simulation of Spirally-Wound, Lithium-Ion Cells

A general approach for the design of cylindrical and prismatic spirally-wound lithium-ion cells that accounts for arbitrary tabbing and coating patterns is presented. Examples are presented for design of high-power and high-energy 18650 size cells. For high-energy cells the current collector design...

Description
Summary:A general approach for the design of cylindrical and prismatic spirally-wound lithium-ion cells that accounts for arbitrary tabbing and coating patterns is presented. Examples are presented for design of high-power and high-energy 18650 size cells. For high-energy cells the current collector design is not critical while for high-power cells the tabbing design is significant especially when thermal effects are considered.
