Modifications to the surface of an electrode and/or the surfaces of the electrode material can improve battery performance. For example, the modifications can improve the capacity, rate capability and long cycle stability of the electrode and/or may minimize undesirable catalytic effects. In one instance, metal-ion batteries can have an anode that is coated, at least in part, with a metal fluoride protection layer. The protection layer is preferably less than 100 nm in thickness. The anode material is fabricated according to methods that result in improved anode performance.
