An electrochemical cell includes a solid-state electrolyte, an anode, and an interfacial layer between the solid-state electrolyte and the anode, wherein the interfacial layer includes a lithium metal sulfide.

Stable lithium metal sulfide coatings for solid-state batteries

Described are embodiments of a laminator and notcher system that pertains to batteries and methods of preparing batteries. In some embodiments, the system includes a laminator configured to densify an electrode film and a notcher configured to receive the densified electrode film from the laminator and cut the densified electrode film into a plurality of electrodes. A web path of the densified electrode film from the laminator to the notcher can have a bend angle greater than 165 degrees.

Nanoporous carbon coated lithium vanadium fluorophosphate materials and cathodes for fast charging li-ion batteries are described. Formation of the materials using polymer-templating is also described.

Nanoporous lithium vanadium fluorophosphate materials and cathodes for fast charging li-ion batteries

A synthetic metal dichalcogenide having a highly defected nanocrystalline layered structure, wherein layer spacing is larger than in perfect crystals of the same material, wherein the defected structure provides access to interlayer crystals of the same material, and wherein the defected structure facilitates a pseudocapacitive charge storage mechanism. The metal dichalcogenide is receptive to intercalation of ions such as Li ions, Na ions, Mg ions, and Ca ions, and does not undergo a phase transition upon intercalation of Li ions, Na ions, Mg ions, or Ca ions. The metal dichalcogenide can be used, for example, as a component of an electrode that also includes a carbon derivative, and a binder, which are intermixed to form the electrode. The resultant composite electrode is highly porous and highly electronically conductive, and is suitable for use in devices such as symmetric capacitors, asymmetric capacitors, rocking chair batteries, and other devices.
