The PHENIX collaboration is in the process of developing an ambitious upgrade plan (called sPHENIX) to significantly improve physics capabilities and make use of the full enhanced luminosity at RHIC. The sPHENIX design contains silicon tracking, electromagnetic and hadronic calorimetry with large kinematic coverage and high data rate capabilities to sample 50 billion Au+Au collisions annually. This poster will describe how additional tracking layers and a preshower detector, will enable us to measure and resolve the three bottomonium Y(1S), Y(2S) and Y(3S) states decaying into di-electrons. Expected mass resolution, signal to background ratios for various assumptions of pion rejection factors will be presented.
