    摘要： A lithium cell for a lithium metal battery includes an electrolyte material, a cathode structure arranged on one side of the electrolyte material, the cathode structure including a cathode electrode and a cathode current collector, and an anode structure arranged on an opposite side of the electrolyte material from the cathode structure. The anode structure includes an anode current collector, a lithium metal anode arranged on a side of the anode current collector arranged facing the electrolyte material, a polymer electrolyte protective coating deposited on a surface of the lithium metal anode arranged facing the electrolyte material. The polymer electrolyte protective coating includes a base polymer material, one or more lithium salts, inorganic filler, dispersant, plasticizer, an initiator, and a rheology modifier.

    摘要： A jetted material printing system includes a carrier substrate configured to travel along a longitudinal direction thereof, one or more printheads, each of the one or more printheads being configured to deposit an amount of material onto the carrier substrate to form a printed layer, a liquid removal device located at a first position from the one or more printheads in the longitudinal direction, and a binder conditioning device located downstream from the liquid removal device in the longitudinal direction and over the carrier substrate. A method of jetted material printing includes depositing material from one or more printheads onto a carrier substrate, the material including at least a powder, a binder and a solvent, removing the solvent from the jetted material, and conditioning the jetted material.

    摘要： A three-dimensional, additive manufacturing system is disclosed. The first and second printer modules form sequences of first patterned single-layer objects and second patterned single-layer objects on the first and second carrier substrates, respectively. The patterned single-layer objects are assembled into a three-dimensional object on the assembly plate of the assembly station. A controller controls the sequences and patterns of the patterned single-layer objects formed at the printer modules, and a sequence of assembly of the first patterned single-layer objects and the second patterned single-layer objects into the three-dimensional object on the assembly plate. The first transfer module transfers the first patterned single-layer objects from the first carrier substrate to the assembly apparatus in a first transfer zone and the second transfer module transfers the second patterned single-layer objects from the second carrier substrate to the assembly apparatus in a second transfer zone. The first and second printer modules are configured to deposit first and second materials under first and second deposition conditions, respectively. The first and second materials are different and/or the first and second deposition conditions are different.

    摘要： A solvent-free powder bed printing process includes depositing a binder-coated powder on a substrate. The binder-coated powder includes a binder that is either thermally curable or a photocurable composition. Optionally, the deposited layer may be densified by a compaction mechanism. A printed pattern is then formed by defined binder curing. This includes selectively curing the binder-coated powder to form a predetermined printed pattern using at least one of heat or light to cure the thermally curable or photocurable composition, respectively. Accordingly, the printed pattern is transferred to a build station or platform. Thus, binder deposition and subsequent drying and solvent recovery in the conventional binder jetting 3D printing have been eliminated. In some embodiments, further processing may occur on the printed pattern layer prior to transferring.
