Abstract: In a method for recycling all solid-state batteries, spent battery cells are dissolved in anhydrous ethanol. The resulting solution is separated into solids and supernatants which are separately processed to regenerate the solid electrolyte and the solid electrode materials. The supernatant is subjected to vacuum evaporation to precipitate an electrolyte powder, which is then annealed under flowing oxygen. The solid electrode material is regenerated by washing the solids with water, drying the washed solids, relithiating the washed solids, and annealing the relithiated solids. The resulting materials are suitable for use in fabrication of new all-solid state batteries.

Abstract: A method for direct recycling of degraded lithium-ion battery (LIB) cathodes includes relithiating degraded lithium nickel cobalt manganese oxide (NCM) by mixing the cathode particles with a eutectic molten-salt solution and heating the mixture at ambient pressure over a period of time, followed by a short-time thermal annealing. Combining low-temperature relithiation using the eutectic molten-salt solution with thermal annealing provides successful regeneration and full recovery of the LIB to its original storage capacity, cycling stability and rate capability to the levels of the pristine materials. The method is useful to recycle and remanufacture degraded cathode materials for LIB or sodium-ion batteries.

Abstract: Various embodiments provide a method for receiving reference signal and a method for sending a reference signal. In those embodiments, a terminal device can determine a location of a resource element to which a reference signal is mapped. The terminal device can determine a reference signal sequence corresponding to the resource element. The index of each element in the reference signal sequence is determined based on a resource block index of a resource block corresponding to the resource element, a quantity of resource elements that carry the reference signal in the resource block, a resource block offset, or an inter-symbol offset. The terminal device can receive the reference signal by using the resource element, and performing channel estimation or channel sounding based on the received reference signal and the reference signal sequence. Therefore, the terminal device can complete channel estimation without learning of a system bandwidth.
