Methods and systems are provided for a battery cathode material comprising greater than or equal to 60% nickel content, the cathode material having at least one metal doped therein. In one example, a method comprises doping the at least one metal into the cathode material using water as a solvent, wherein the at least one metal has an ionic radii greater than 60 picometers. The at least one metal may be selected from strontium (Sr), barium (Ba), rubidium (Rb), cesium (Cs), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), tungsten (W), platinum (Pt), neodymium (Nd), yttrium (Y), and cerium (Ce).

Method and systems for metal doping on battery cathode materials

Methods and systems are provided for a cathode material for lithium ion batteries. In one example, the cathode material may include a lithium mixed metal oxide core and a surface coating surrounding the core. Optionally, a passivating layer may continuously surround the surface coating. In some examples, the surface coating or surface layer may include a sacrificial lithium source, a lithium-based active cathode catalyst, or a combination thereof. In other examples, methods are provided for manufacturing the cathode material for use in a lithium ion battery.

Cathode with pre-lithiation coating and methods for preparation and use

A lithium iron phosphate electrochemically active material for use in an electrode and methods and systems related thereto are disclosed. In one example, a lithium iron phosphate electrochemically active material for use in an electrode is provided including, a dopant comprising vanadium and optionally a co-dopant comprising cobalt.

Nanoscale pore structure cathode for high power applications and material synthesis methods

A coated cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for applying a coating to an active cathode material for use in a lithium-ion battery. In one example, the coated cathode material may include a high-nickel content active cathode material, such as lithium nickel manganese cobalt oxide or lithium nickel aluminum cobalt oxide, coated with a coating including one or more high energy density active materials, such as lithium vanadium fluorophosphate and/or a lithium iron manganese phosphate compound. In some examples, the high-nickel content active cathode material may include greater than or equal to 60% nickel content.

Method and systems for coated cathode materials and use of coated cathode materials

A binder for an electrode is provided herein. In one example, the electrode may include a current collector, and an electrode coating layer, the electrode coating layer including an electrode active material and a binder, where the binder may comprise an aromatic polyamide-based compound, and the binder may be present at greater than 0 wt % and less than or equal to 30 wt % of the electrode coating layer. In one example, the binder provides stronger cohesion between particles of the electrode active material. Methods and systems are further provided for fabricating the electrode including the binder.

Polymer binder additives for electrodes

Materials and methods for a coated active electrode material for use in a lithium-ion battery is provided. In one example, a coating for an active electrode material or active electrode material precursor of an electrode of a battery cell may include lithium, boron, and oxygen. In particular, the coating may include lithium tetraborate (LBO), and the coating may be coated on a lithium insertion electrode active material such as lithium nickel manganese cobalt oxide (LiNiMnCoOor NMC).

Lithium tetraborate glass coating on cathode materials for improving safety and cycling stability

A doped cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for doping a cathode material for use in a lithium-ion battery. In one example, the doping may be a dry surface doping process. In some examples, dopants may stabilize a crystal structure of the cathode material and may result in fewer side reactions with an electrolyte as compared to an undoped cathode material. As such, cycling performance and capacity retention may be improved relative to the undoped cathode material. Further, in some examples, the doped cathode material produced with the dry surface doping process may have improved cycling performance and capacity retention relative to a comparable doped cathode material produced with a wet surface doping process.

Methods and systems for dry surface doping of cathode materials

Systems and methods are provided for a slurry for coating an electrode structure. In one example, a method may include dispersing, by mixing at one or both of a high shear and a low shear, a solid ionically conductive polymer material in at least a first portion of a solvent to form a suspension, then dispersing, by mixing at the one or both of the high shear and the low shear, one or more additives in the suspension, and then mixing, at the one or both of the high shear and the low shear, a second portion of the solvent with the suspension to form a slurry. As such, the slurry including the solid ionically conductive polymer material may be applied as a coating in a solid-state battery cell, which may reduce resistance to Li-ion transport and improve mechanical stability relative to a conventional solid-state battery cell.

Systems and methods for a composite solid-state battery cell with an ionically conductive polymer electrolyte

Methods and systems are provided for salt-rinse surface doping of electrode materials for lithium-ion batteries. In one example, a method may include dissolving a dopant salt in a solvent to form a dopant salt rinse solution, rinsing an electrode active material with the dopant salt rinse solution to form a coated electrode active material, and heating the coated electrode active material to form a doped electrode active material. In some examples, a surface region of the doped electrode active material may include a uniform distribution of dopants from the dopant salt rinse solution. In this way, the electrode active material may be rinsed and doped via the dopant salt rinse solution in a single-stage process.

In one example, an electrochemically active electrode material comprises: a polymer coating applied directly to an exterior surface of the electrochemically active electrode material; a metal plating catalyst adhered to the continuous polymer; and a continuous metal coating that completely covers the metal catalyst and continuous polymer coating. The electrochemically active electrode material may comprise a powder comprising one or more secondary particles, and the polymer and metal coatings may be applied to exterior surfaces of these secondary particles.

A lithium-ion battery including an electrodeposited anode material having a micron-scale, three-dimensional porous foam structure separated from interpenetrating cathode material that fills the void space of the porous foam structure by a thin solid-state electrolyte which has been reductively polymerized onto the anode material in a uniform and pinhole free manner, which will significantly reduce the distance which the Li-ions are required to traverse upon the charge/discharge of the battery cell over other types of Li-ion cell designs, and a procedure for fabricating the battery are described. The interpenetrating three-dimensional structure of the cell will also provide larger energy densities than conventional solid-state Li-ion cells based on thin-film technologies. The electrodeposited anode may include an intermetallic composition effective for reversibly intercalating Li-ions.
