Articles and methods involving protective membranes for electrochemical cells are generally provided. In some embodiments, a composite protective layer comprising particles and a polymeric binder may be disposed on an electroactive material. The particles may be reactive with lithium, may capable of intercalating lithium, and/or may comprise intercalated lithium. In some embodiments, the electroactive material may be in the form of a first electroactive layer, and a second electroactive layer may be disposed on the composite protective layer. Certain embodiments relate to activating a composite protective layer by intercalating lithium into particles within the layer and/or by reacting the particles with lithium metal.

Protective membrane for electrochemical cells

An electrode structure and its method of manufacture are disclosed. The disclosed electrode structures may be manufactured by depositing a first release layer on a first carrier substrate. A first protective layer may be deposited on a surface of the first release layer and a first electroactive material layer may then be deposited on the first protective layer.

Protected electrode structures

Electrochemical devices that include porous layers, and associated methods, are generally described. In certain cases, the electrochemical device includes a first layer (e.g., a porous coating containing nanoparticles) between an anode and a separator, and a second layer (e.g., another porous coating containing nanoparticles) between a cathode and the separator. The first layer and/or the second layer may have a relatively high porosity, even after the application of an applied pressure to the electrochemical device. The presence of the first layer and the second layer in the electrochemical device may mitigate the occurrence of certain problematic phenomena during cycling of the electrochemical device.

Electrochemical devices including porous layers

Articles and methods including composite layers for protection of electrodes in electrochemical cells are provided. In some embodiments, the composite layers comprise a polymeric material and a plurality of particles.

Ion-conductive composite for electrochemical cells

The use of fibril materials, such as fibril cellulose materials and other similar materials, in electrochemical cells and components thereof is generally described.
