"MXenes do not just store charge physically but undergo complex chemical surface redox reactions that vary based on electrolyte... proton-based electrolytes lead to titanium atom oxidation state reduction... li-ion electrolytes lead to titanium atom oxidation state increase... bridges gap between batteries/ capacitors... layered 2D titanium carbide with conductive cores/ reactive surfaces... function with eco-friendly aqueous electrolytes... precise optimization for future energy storage materials"
