An improved energy clustering algorithm is introduced, and its implications for the measurement and identification of prompt electrons and photons are discussed in detail. Corrections and calibrations that affect performance, including energy calibration, identification and isolation efficiencies, and the measurement of the charge of reconstructed electron candidates are determined using up to 81 fb(-1) of proton-proton collision data collected at root s = 13 TeV between 2015 and 2017. %K Particle identification methods %K Performance of High Energy Physics Detectors %R 10.1088/1748-0221/14/12/P12006 %U https://arxiv.org/abs/1908.00005 %U https://doi.org/10.1088/1748-0221/14/12/P12006 %P P12006 - 69pp
