Disclosed herein are embodiments of systems and methods for recycling used solid feedstocks containing lithium powders for use in lithium-ion batteries. The used solid feedstocks may be Lithium Nickel Manganese Cobalt Oxide (NMC) materials. In some embodiments, the used solid feedstock can undergo a microwave plasma process to produce a newly usable, lithium supplemented solid precursor with augmented chemistries and physical properties.

Methods and systems for reclamation of Li-ion cathode materials using microwave plasma processing

The embodiments disclosed herein are directed to systems, methods, and devices for processing a material using a microwave plasma apparatus with an interior liner. In some embodiments, the liner comprises a reduction resistant material layer in direct contact with a hydrogen-containing plasma of a plasma processing apparatus. In some embodiments, the liner may comprise a sleeve disposed between a plasma and one or more concentric tubes of a plasma processing apparatus. In some embodiments, the liner may comprise a coating of material applied to the one or more concentric tubes. In some embodiments, the liner may comprise a flexible ceramic material, such as a ceramic ribbon that is coiled or wrapped in a helix shape spiraling around the interior of the one or more concentric tubes.

Microwave plasma apparatus and methods for processing materials using an interior liner

Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing semi-solid electrodes and batteries incorporating semi-solid electrodes. In some embodiments, the process of manufacturing a semi-solid electrode includes continuously dispensing a semi-solid electrode slurry onto a current collector, separating the semi-solid electrode slurry into discrete portions, and cutting the current collector to form a finished electrode.

Continuous and semi-continuous methods of semi-solid electrode and battery manufacturing

Disclosed herein are embodiments of strain tolerant particles, methods of manufacturing such structures, and feedstock to form said structures. In some embodiments, the structures can include alternating regions of an energy storage structure and a reinforcing structure. Advantageously, when the strain tolerant particles are used within an anode of a lithium ion battery, the reinforcing structure may provide mechanical stability to the particles and thus increase cycle life.

Microcomposite alloy structure

Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cells includes an anode and a semi-solid cathode. The semi-solid cathode includes a suspension of an active material of about 35% to about 75% by volume of an active material and about 0.5% to about 8% by volume of a conductive material in a non-aqueous liquid electrolyte. An ion-permeable membrane is disposed between the anode and the semi-solid cathode. The semi-solid cathode has a thickness of about 250 &#x3bc;m to about 2,000 &#x3bc;m, and the electrochemical cell has an area specific capacity of at least about 7 mAh/cmat a C-rate of C/4. In some embodiments, the semi-solid cathode slurry has a mixing index of at least about 0.9.

Semi-solid electrodes having high rate capability

Disclosed herein are embodiments of doped and undoped spherical or spheroidal lithium lanthanum zirconium oxide (LLZO) powder products, and methods of production using microwave plasma processing, which can be incorporated into solid state lithium ion batteries. Advantageously, embodiments of the disclosed LLZO powder display a high quality, high purity stoichiometry, small particle size, narrow size distribution, spherical morphology, and customizable crystalline structure.

Lithium lanthanum zirconium oxide (LLZO) powder

Embodiments described herein relate generally to systems and methods for improving safety features in electrochemical cells. In particular, the systems and methods as described herein can solve safety issues concerning gas generation in electrochemical cells.

Systems and methods for improving safety features in electrochemical cells

Embodiments described herein relate generally to a current interrupt device (CID) including a frangible bulb that is configured to be thermally triggered. In some embodiments, the CID includes a breaking contact electrically coupled to a fixed contact and held in electrical contact by the frangible bulb. In some embodiments, the frangible bulb is configured to break at a temperature threshold. In some embodiments, the breaking contact is configured to bend, rotate and/or otherwise deform about a hinge point in order to become electrically disconnected from the fixed contact when the frangible bulb breaks. In some embodiments, opening the electrical circuit between the breaking contact and the fixed contact may prevent overcharging, overvoltage conditions, overcurrent conditions, thermal runaway, and/or other catastrophic failure events.

Current interrupt device based on thermal activation of frangible glass bulb

Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cell includes an anode and a semi-solid cathode. The semi-solid cathode includes a suspension of an active material of about 35% to about 75% by volume of an active material and about 0.5% to about 8% by volume of a conductive material in a non-aqueous liquid electrolyte. An ion-permeable membrane is disposed between the anode and the semi-solid cathode. The semi-solid cathode has a thickness of about 250 &#x3bc;m to about 2,000 &#x3bc;m, and the electrochemical cell has an area specific capacity of at least about 7 mAh/cmat a C-rate of C/4. In some embodiments, the semi-solid cathode slurry has a mixing index of at least about 0.9.

Embodiments described herein relate generally to electrodes for electrochemical cells, the electrodes including an electrode material disposed on a current collector. In some embodiments, an electrode includes an edge protection barrier member on a perimeter of a surface of the current collector. The barrier member forms a wall along the main edge(s) of the current collector, defining an inner region bounded by the barrier member and the top surface of the current collector, and the electrode material occupies the inner region.
