Abstract
An electrode for an electrochemical energy store, including an active material layer having an active material, a protective layer being at least partially applied to the active material, and the protective layer at least partially including a fluorophosphate-based material. Such an electrode offers a particularly high stability, even when high voltages are present. Also described is a method for manufacturing an electrode, to an electrochemical energy store and to the use of a fluorophosphate-based material for generating a protective layer for an active material of an electrode of an electrochemical energy store.
Claims11
An electrode for an electrochemical energy store, comprising:
- an active material layer having an active material, wherein a protective layer is at least partially applied to the active material, and the protective layer at least partially includes a fluorophosphate-based material.
An energy store, comprising:
- at least one electrode for an electrochemical energy store, including:
- an active material layer having an active material, wherein a protective layer is at least partially applied to the active material, and the protective layer at least partially includes a fluorophosphate-based material.
A method for manufacturing an electrode for an energy store, the method comprising:
- (a) providing an active material;
- (b) if necessary, adding a conductive additive;
- (c) if necessary, adding a binder;
- (d) at least partially coating the active material with a protective layer, the protective layer at least partially including a fluorophosphate-based material, or a precursor of a fluorophosphate-based material;
- (e) combining a current collector with the generated mixture;
- and
- (f) if necessary, compressing the manufactured electrode.
A fluorophosphate-based material comprising:
- a fluorophosphate-based material for generating a protective layer for an active material of an electrode of an electrochemical energy store;
- wherein the electrode is for an electrochemical energy store, and includes:
- an active material layer having an active material, wherein a protective layer is at least partially applied to the active material, and the protective layer at least partially includes a fluorophosphate-based material.
