Abstract
Additives for energy storage devices comprising phosphorus-containing compounds are disclosed. The energy storage device comprises a first electrode and a second electrode, where at least one of the first electrode and the second electrode is a Si-based electrode, a separator between the first electrode and the second electrode, and an electrolyte composition. Phosphorus-containing compounds may serve as additives to the first electrode, the second electrode and/or the electrolyte, as well as the separator.
Claims16
An energy storage device comprising:
- a first electrode and a second electrode, wherein one or both of the first electrode and the second electrode is a Si-based electrode;
- a separator between the first electrode and the second electrode;
- and
- an electrolyte composition;
- wherein
- one or more of said first electrode, said second electrode and said electrolyte composition comprises at least one additive, wherein said additive comprises a phosphorus-containing compound.
(canceled)
A method of forming an energy storage device, the method comprising:
- forming an energy storage device comprising a cathode, an electrolyte composition, and an anode;
- wherein one or more of said anode, said cathode and said electrolyte composition comprises at least one additive, wherein said additive comprises a phosphorus-containing compound;
- wherein one or both of said cathode and said anode is formed using, at least, the following steps:
- said electrode material is mixed to create a slurry;
- said additive is added to said slurry;
- said slurry is coated on metal foil;
- and
- the coated metal foil is dried.
