Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing electrochemical cells with semi-solid electrodes. In some embodiments, a method can include mixing an active material, a conductive material, and an electrolyte to form a semi-solid electrode material. The method further includes drawing a vacuum on the semi-solid electrode material, compressing the semi-solid electrode material to form an electrode brick, and dispensing a portion of the electrode brick onto a current collector via a dispensation device to form an electrode. In some embodiments, the current collector is disposed on a pouch material. In some embodiments, the dispensation device includes a top blade for top edge control and two side plates for side edge control. In some embodiments, the method can further include conveying the electrode through the top blade and the two side plates to shape the electrode.

Methods of continuous and semi-continuous production of electrochemical cells

A system and corresponding method for additive manufacturing of a three-dimensional (3D) object to improve packing density of a powder bed used in the manufacturing process. The system and corresponding method enable higher density packing of the powder. Such higher density packing leads to better mechanical interlocking of particles, leading to lower sintering temperatures and reduced deformation of the 3D object during sintering. An embodiment of the system comprises means for adjusting a volume of a powder metered onto a top surface of the powder bed to produce an adjusted metered volume and means for spreading the adjusted metered volume to produce a smooth volume for forming a smooth layer of the powder with controlled packing density across the top surface of the powder bed. The controlled packing density enables uniform shrinkage, without warping, of the 3D object during sintering to produce higher quality 3D printed objects.

System and method for controlling powder bed density for 3D printing

A de-powdering basket comprises an enclosure of at least one side wall and a bottom wall. The enclosure is configured such that, when the enclosure is disposed within a build box, the outer surfaces of the at least one side wall are substantially adjacent to the interior walls of the build box. The enclosure further comprises one or more apertures disposed within the at least one side wall, each of the apertures comprising a void that extends through the at least one side wall from an interior surface of the side wall to an exterior surface of the side wall. The enclosure may be configured to accommodate a build plate situated within the enclosure. Outer edges of the build plate may cooperate with inner surfaces of the side walls of the enclosure to prevent loose powder from passing between the outer edges of the build plate and the side walls.

Systems, devices, and methods for additive manufacturing

A personal impact protection device () with a first mechanical member () that may be a shell, ring or housing, and a second mechanical member () that may also be a shell, ring or housing. The two mechanical members () are nested and spaced from one another. One or more elastomeric energy-absorption members () are mechanically coupled to and span the distance between both of the mechanical members () to absorb energy from impacts to the outer mechanical member () that displace the outer member () relative to the inner member ().

Personal impact protection device

An engine, such as a circulating piston engine, includes a housing that defines an annular bore, a piston assembly, and a valve. The piston assembly is disposed within the annular bore and is configured to be coupled to a drive mechanism. The valve is configured to be intermittently disposed within the annular bore to define a combustion chamber relative to the piston assembly.

Circulating piston engine

A universal mounting system for mounting communication equipment of various sizes within an automobile. The console's universal mounting system allows for the mounting of any of a wide variety of relatively standard communication equipment. The universality of the mounting system allows for field upgrading or repositioning of the communication equipment without replacing or making changes in the mounting hardware.
