An improved method of recycling lithium-ion battery anode scraps is provided. The method involves isolating an anode scrap including a graphite anode film adhered to a current collector foil with a polyvinylidene fluoride binder. The anode scrap is combined with deionized water to form a first mixture. The graphite anode film is delaminated from the current collector foil to form a second mixture comprising a free collector foil and a free graphite anode film. The free graphite anode film is filtered and dried from the second mixture to recover the free graphite anode film. The free graphite anode film is combined with a solvent comprising N-methyl-2-pyrrolidone (NMP) to form an anode formation slurry. The slurry is coated onto a copper current collector to produce a new anode.

A battery pack contains a plurality of battery cells that includes a first battery cell and a second battery cell; a first thermistor disposed closest to the first battery cell among the battery cells; a second thermistor disposed closest to the second battery cell among the battery cells. A case of the battery pack holds the battery cells, the first thermistor, and the second thermistor. The first battery cell is disposed such that at least one of the other battery cells is interposed between the first battery cell and a wall surface of the case in a direction orthogonal to a longitudinal direction of the first battery cell. The second battery cell is disposed such that none of the other battery cells is interposed between the second battery cell and the wall surface of the case in a direction orthogonal to a longitudinal direction of the second battery cell.

A pouch battery cell includes a rigid frame forming a skeleton of the cell and defining an aperture, an anode, a separator, a cathode, and a thermal transfer device disposed within the aperture, the anode and cathode each including a current collector with an exposed tab portion bonded to a terminal, integrated into the frame, and the thermal transfer device integrated into the frame and partially extending to the cell exterior.

An apparatus includes a frame component of a head-mounted device (HMD), an eyepiece, a battery, a processor, a heat pipe, and a hinge. The frame component includes a first compartment, a second compartment, and a channel connecting the first compartment and the second compartment. The heat pipe may extend from the first compartment to the second compartment through a channel and may be configured to transfer heat from the processor to the battery. A rate of heat transfer through the hinge may be greater than a threshold value when the hinge is in an open conformation that configures the frame component to be positioned along the side of the head. The heat transfer through the hinge may be smaller than the threshold value when the hinge is in a folded conformation that configures the frame component to be positioned for storage.
