Abstract
Cathode active materials coated with a boron-containing additive are useful for suppressing thermal events when used in an electrochemical cell. Electrochemical cells may include a cathode layer that includes a boron additive, or may include a layer that contains the boron additive.
Claims20
A composition comprising a boron additive and a cathode active material having a surface, wherein the boron additive is in physical contact with the surface of the cathode active material.
An electrochemical cell comprising:
- a first current collector layer;
- a cathode layer;
- a boron additive-containing layer comprising a boron additive and having a thickness from about 0.5 μm to about 15 μm, wherein the boron layer is positioned between the first current collector layer and the cathode layer;
- a separator layer;
- an anode layer;
- and
- a second current collector layer.
