Abstract: Aspects of the disclosure include an electrode coating having a spatially varied porosity and a method of forming the same by using a porous current collector. An exemplary method can include forming a porous current collector having a bulk material and a plurality of voids. The porous current collector can be coated, infused, or otherwise saturated with an electrode coating having an active electrode material. The porous current collector and the electrode coating can be compressed in a calendering process to define the electrode film. The distribution of the plurality of voids in the porous current collector provides for regions of different calendering pressures during the calendering process. The regions of different calendering pressures leads to regions of higher and lower porosity in the resultant electrode film. In other words, an electrode film having a spatially varied porosity.

Abstract: A method of soldering a shape memory alloy (SMA) element to a component includes positioning a tinned end of the SMA element with respect to a surface of the component, and then directly soldering the tinned end to the surface using solder material having a low liquidus temperature of 500° F. or less when an oxide layer is not present on the SMA element. The end may be soldered using lead-based solder material at a higher temperature when an oxide layer is present. The end may be tinned with flux material containing phosphoric acid or tin fluoride prior to soldering the SMA element. The SMA element may be submersed in an acid bath to remove the oxide layer. The solder material may contain tin and silver, antimony, or zinc, or other materials sufficient for achieving the low liquidus temperature. Heat penetrating the SMA element is controlled to protect shape memory abilities.

Abstract: A functionalized adhesive and systems and methods employing the same are disclosed. The functionalized adhesive is configured to form an adhesive joint between a first substrate and a second substrate. The functionalized adhesive comprises a neat adhesive selected to have a bonding strength above a predetermined bonding threshold and a filler selectively dispersed within the neat adhesive. The filler is selected to modify electrical properties of the neat adhesive such that the functionalized adhesive is electrically conductive with a tailored resistivity and such that a resistance of the adhesive joint is greater than a resistance of the first substrate and the second substrate.

Abstract: A method of making a calendered electrode for a battery cell comprises introducing a coated electrode having a first surface extending thereover. The coated electrode has a predetermined density of active materials for ion transport. The method further comprises selectively modifying the coated electrode by patterning the first surface to define a patterned electrode having a first portion and a second portion. After the step of selectively modifying, the method further comprises compressing the patterned electrode by calendering the first surface to provide the first portion having a first density of active materials and the second portion having a second density of active materials. The second density is greater than the first density to define the calendered electrode having a spatial variation of active material density.

Abstract: Methods for pre-lithiating negative electrodes for lithium-ion electrochemical cells (e.g., batteries) are provided. The methods include disposing a lithium metal source comprising a layer of lithium metal adjacent to a surface of a pre-fabricated negative electrode. The lithium metal source and electrode are heated (e.g., to a temperature of ≧about 100° C.) to transfer a quantity of lithium to the pre-fabricated negative electrode. This lithiation process adds excess active lithium capacity that enables replacement of irreversibly lost lithium during cell formation and cell aging, thus leading to increased battery capacity and improved battery life. The methods may be batch or continuous.
