Abstract:
An anode electrode with enhanced state of charge estimation is provided. The anode electrode comprises anode layer and a negative current collector. The negative current collector has a first side and a second side. The anode layer comprises lithium-titanium oxide and a second anode material (e.g. niobium-titanium oxide) disposed on at least one of the first and second sides of the negative current collector with single-layer or layer-by-layer coated structures. The second anode material (e.g. niobium-titanium oxide) can be physically blended with lithium-titanium oxide or be at least partially coated on the surface of lithium-titanium oxide or their combinations. The anode electrode further comprises a binder and a conductive carbon.
