Embodiments described herein include electrochemical cell modules. In some aspects, an electrochemical cell module includes a first electrochemical cell and a second electrochemical cell. The first electrochemical cell includes an anode material disposed on an anode current collector, a cathode material disposed on a cathode current collector, a separator disposed between the anode material and the cathode material, and a pouch material disposed on the anode current collector and the cathode current collector. The separator extends beyond the anode material and the cathode material and the pouch material extends beyond the separator. The portion of the separator that extends beyond the outer edge of the anode material and the cathode material and the portion of the pouch material that extends beyond the outer edge of the separator are folded at an angle of about 80 degrees to about 110 degrees with respect to the anode material and the cathode material.

Embodiments described herein relate to regeneration of lithium-deficient electrodes (e.g., lithium iron phosphate, LFP). The process includes multiple steps of heat treatment. The first step includes mixing spent electrode material with lithium carbonate. The lithium carbonate and the spent LFP are then subject to a heating process in an all-nitrogen environment. The first heat treatment brings the materials up to about 550° C. to remove excess water and oxygen. The second heat treatment brings the materials up to about 1,000° C., where they are sintered together to form a like-new electrode material.

Electrochemical cells including selectively permeable membrane and semi-solid electrodes, and method of manufacturing the same

Номер: US12107211B2
Автор: Jeffry DISKO, Junzheng CHEN, Naoki Ota, Yuki Kusachi
Принадлежит: 24M Technologies Inc

Embodiments described herein relate generally to electrochemical cells including a selectively permeable membrane and systems and methods for manufacturing the same. In some embodiments, the selectively permeable membrane can include a solid-state electrolyte material. In some embodiments, electrochemical cells can include a cathode disposed on a cathode current collector, an anode disposed on an anode current collector, and the selectively permeable membrane disposed therebetween. In some embodiments, the cathode and/or anode can include a slurry of an active material and a conductive material in a liquid electrolyte. In some embodiments, a catholyte can be different from an anolyte. In some embodiments, the catholyte can be optimized to improve the redox electrochemistry of the cathode and the anolyte can be optimized to improve the redox electrochemistry of the anode. In some embodiments, the selectively permeable membrane can be configured to isolate the catholyte from the anolyte.

Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material. In some embodiments, the method includes mechanically compressing the intermediate electrode to remove the portion of electrolyte from the semi-solid electrode material.
