A wide microporous film comprises one or more layers comprising a polyolefin; wherein the film has a width of a least 40 inches, at least 45 inches, at least 50 inches, at least 55 inches, at least 60 inches, at least 65 inches, or at least 70 inches.

Provided is a coating die enabling coating of two layers of coating films stably. The coating die includes: a first block including a first manifold to receive a first coating liquid; a second block including a second manifold to receive a second coating liquid; and a shim sandwiched between the first block and the second block.

A laminating device includes: multiple laminating heads that each hold a unit laminated body; a drum section that holds multiple laminating heads; a drum drive unit that rotates the drum section to advance each laminating head to a laminating position that faces a lamination stage; and multiple head drive units that move the respective laminating heads independently of the move made by the rotation of the drum section. A head drive unit for a laminating head that has reached the laminating position drives the laminating head such as to offset the advancement of the laminating head made by the rotation of the drum section. Each laminating head discharges, onto the lamination stage, a unit laminated body so that multiple unit laminated bodies are laminated.

The invention provides a method for delaminating a composite by immersing the composite into a delamination solution; wherein the composite comprises a metal substrate and a coating applied on one side or both sides of the metal substrate, wherein the coating comprises a polymeric binder; and wherein the polymeric binder comprises an aqueous copolymer. The use of delamination solution comprising a weak base allows for complete delamination of the composite in a highly efficient and extremely fast manner. Furthermore, the delamination method disclosed herein circumvents complex separation processes, contamination and corrosion of the metal substrate and enables an excellent materials recovery. An application of the method for delaminating an electrode for a battery is disclosed herein.

A pouch film laminate for preparing a pouch type battery case accommodating an electrode assembly is provided. The pouch film laminate includes a sealant layer formed of a first polymer as an innermost layer, a surface protection layer formed of a second polymer as an outermost layer, an aluminum alloy thin film having a grain size of 10 μm to 13 μm, and a gas barrier layer laminated between the surface protection layer and the sealant layer, wherein the gas barrier layer has a thickness of 50 μm to 70 μm, and the sealant layer has a thickness of 70 μm to 100 μm.

A thermal management system.

An example of a thermal composite includes a substrate, a primer layer, a first adhesive layer, a blanket layer, a second adhesive layer, and a metal layer. The blanket layer includes basalt fibers or glass fibers. The thermal composite may be incorporated into a battery pack as a battery enclosure.

In one embodiment, each of the expanded and interconnected carbon layers is made up of at least one corrugated carbon sheet that is one atom thick. In another embodiment, each of the expanded and interconnected carbon layers is made up of a plurality of corrugated carbon sheets that are each one atom thick. The interconnected corrugated carbon-based network is characterized by a high surface area with highly tunable electrical conductivity and electrochemical properties.

A multi-layer heat insulation element for thermal insulation of a battery is proposed, with a first cover layer, with a second cover layer and with a compressible and/or pliable intermediate ply arranged between the cover layers, which has at least one heat-resistant fibre layer, wherein the fibre layer is formed from a needled nonwoven and/or wherein the cover layers are flexurally weak and the heat insulation element as a whole is compressible and flexibly pliable.

Disclosed herein are a metal-polymer laminate structure having an enhanced flame protection function as well as a method for preparing the same. The metal-polymer laminate structure includes a metallic layer, at least one polymeric layer provided on the metallic layer, and a backing layer provided on the at least one polymeric layer. The at least one polymeric layer includes an intumescent material, and a first functional layer is interposed between the metallic layer and the at least one polymeric layer. The first functional layer is a thermoplastic layer constructed from a material selected from polyamide, thermoplastic polyurethane, hotmelts, preferably polyamides such as PA6, PA6/6.36, PA6/66, PA12, PA6.12, PA6.10, PA6I/6T, copolymers of caprolactam or lauryllactam, thermoplastic polyurethane, and polyether block co-polyamides or combinations thereof.
