This report presents a battery essentials (BEF) of the Sunwoda A2866 stacked pouch Li-ion battery, extracted from the Apple iPhone 14 Pro.
The BEF includes a summary of observed device metrics and salient features with supporting images and data. The summary is supported by the following unannotated image folders:

• Product teardown images
• Package optical photographs and package X-Ray
• Electrochemical impedance spectroscopy of the battery
• Differential capacity analysis of the battery
• Plan-view SEM images of the separated battery layers
• Optical and cross-sectional scanning electron microscope (SEM) images of the battery structure
• Results of SEM-based energy dispersive spectroscopy (SEM-EDS) analysis of the battery materials
• X-ray powder diffraction (XRD) of the anode and cathode
• Fourier-Transform infrared (FTIR) analysis of the separator
• Gas chromatography mass spectrometry (GCMS) analysis of the electrolyte solution

The Battery Essentials deliverable provides basic competitive benchmarking information and enables cost-effective tracking of multiple competitors’ technology
