Experimental and simulation study on thermal characteristics of 18,650 lithium–iron–phosphate battery with and without spot–welding tabs

•The effects of spot-welded nickel strip on battery performance are studied experimentally.•The effects of ambient temperature on internal heat generation of 18,650 LPF is analyzed.•A two-dimensional electrochemical–thermal coupled model of 18,650 LPF is established. Thermal condition is crucial to...
