Pre-lithiated Li4+xTi5O12 (0 ≤ x ≤ 3) anodes towards building high-performance Li-ion capacitors

A 180° faradaic shift is observed for a completely pre-lithiated Li 4 Ti 5 O 12 anode when paired with an activated carbon cathode. The optimum range of pre-lithiation certainly enables attaining high energy and high power Li-ion capacitors.
