Abstract:

This ground breaking invention enables Li-ion batteries to operate at high voltage 5V, which is impossible with current state-of-art electrolytes. There is a strong commercial interest in high voltage, or 5V Li ion batteries Various candidates LiCoPO4, LiNi0.5Mn1.5O4, Li2FeCoPO4 etc, projected to deliver 1540 more energy than state-of-art LiFePO4 The additive invented by SEDD is easy to prepare, low in cost and causes minimum impact on the existing battery manufacturing processing The electrolyte formulated is an open and flexible system that is compatible with multiple cathode chemistries Demonstrated on LiCoPO4 in a previous presentation Now on spinel systems
