Here are some papers with spice models. I have used similar ideas when creating
spice models of lithium batteries.

Subject: [SI-LIST] Battery impedance
Hi all, I'm doing PDN analysis on mobile battery powered device and considering
how to model the battery as voltage source. Data sheets for these types of
batteries typically have specification for DC impedance and/or AC @ 1KHz
impedance, but I need impedance profile data to several MHz.
Any ideas or resource links about this? Thanks, Ivor
