The present embodiments are directed to systems and methods for plating of work rolls. In one embodiment, a system includes an inner tank having an inner diameter dimensioned to receive a work roll, and an outer tank, wherein the inner tank is disposed coaxially within the outer tank. The inner tank and the outer tank may each include cylindrical shapes. A temperature regulating tank, positioned outside of the outer tank, may be in fluid communication with an annular space between the inner and outer tanks. An exhaust hood having a generally ring-shaped profile including a plurality of slots formed therein may suction fumes from the inner tank. An anode configuration also is disclosed, having a shunt incorporated into the anode, wherein current going to the anode passes through the shunt.

Electrochemical deposition systems and methods are described that have enhanced crystallization prevention features. The systems may include a bath vessel operable to hold an electrochemical deposition fluid having a metal salt dissolved in water. The systems may also include sensors including a thermometer and concentration sensor operable to measure characteristics of the electrochemical deposition fluid. The systems further include a computer configured to perform operations that include receiving system data from the electrochemical system and generating a control signal to change a characteristic of the electrochemical deposition fluid to prevent crystallization of a metal salt in the fluid. The computer generates the control signal based on processing that may include comparing an actual metal salt concentration in the electrochemical deposition fluid to a theoretical solubility limit for the metal salt in the fluid.

A workpiece holding jig for holding a plate-shaped workpiece that is an object to be electroplated, includes a frame and a back panel. The frame includes an annular body, a conductive member, a contact member, an inner seal member, and an outer seal member. The frame forms a sealed space between the inner seal member and the outer seal member, that accommodates the peripheral edge, the conductive member, and the contact member. The inner seal member has a column and a lip in order from outside to inside, the column protrudes toward the back panel so as to come into pressure contact with the peripheral edge of the workpiece when holding the workpiece, and the lip protrudes toward the back panel to the same extent as that of the column, with at least a tip portion of the lip inclined outward.

Process for the fabrication of an electrode structure comprising an electrochemically active material suitable for use in an energy storage device. The method includes electrodepositing the electrochemically active material onto an electrode in electrodeposition bath containing a non-aqueous electrolyte. The electrode structure can be used for various applications such as electrochemical energy storage devices including high power and high-energy lithium-ion batteries.

A liquid storage device includes a tank body including multiple working cycle drain ports for supplying solution to multiple work chambers and a thermal cycle liquid injection port for introducing heated solution into the tank body. The working cycle drain ports are located on opposing side walls of the tank body. A side wall connecting the two side walls has the thermal cycle liquid injection port positioned near or at the middle of the length of the side wall. The liquid storage device further includes a guide element located inside the tank body. The guide element is connected to the thermal cycle liquid injection port, allowing the solution entering from the thermal cycle liquid injection port to flow through the guide element into the tank body and toward each of the working cycle drain ports.
