What property of the material determines the working voltage (working voltage window) of the anode material for Lithium ion batteries?

I have noticed that TiO2, MnO2 and Si are working with very different end voltages, i.e. Si stops at 0V, TiO2 stops at 1V etc. I understand that the end voltage is to protect the material from...
