A method of manufacturing a secondary-battery electrode (10), which is an example of an embodiment, comprises a first step of forming an active material layer (22) on at least one surface of a long core body (21). The method of manufacturing the secondary-battery electrode (10), which is an example of the embodiment also comprises a second step of cutting an electrode precursor (20) into a predetermined shape by using a continuous wave laser, the electrode precursor (20) being the long core body (21) having the active material layer (22) formed thereon.

Methods of separating a glass web include exposing a separation path on the glass web to a laser beam that produces thermal stress along the separation path without damaging the glass web. The methods further include redirecting a portion of the laser beam to create a defect on the separation path while the separation path is under thermal stress produced during the exposing the separation path on the glass web to the laser beam, whereupon the glass web separates along the separation path in response to creating the defect. Apparatus are further provided for separating a glass web with at least one laser beam generator that produces a laser beam to heat a separation path and a mirror configured to reflect an end portion of the laser beam to create a defect at a location of the separation path on the glass web.

Discussed is an electrode manufacturing method, in which laser ablation is performed prior to cutting an electrode sheet so that a processing speed of cutting the electrode sheet by using laser is increased, and an electrode forming device for performing same.

Embodiments of the present disclosure generally relate to flexible substrate fabrication. In particular, embodiments described herein relate to methods for flexible substrate fabrication which can be used to improve the life of lithium-ion batteries. In one or more embodiments, a method of fabricating alloy anodes includes forming an alloy anode using a planar flow melt spinning process including solidifying a molten material over a quenching surface of a rotating casting drum and performing a pre-lithiation surface treatment on the alloy anode.

A reel-to-reel method to laser-ablate a circuitry pattern on the fly in a reel-to-reel machine as part of a process to fabricate a printed flexible circuit. The laser ablation method includes using an appropriate laser to irradiate a metal sheet thus ablating the edges of an intended circuitry pattern. Slugs can be removed by using an optional sacrificial liner, and the slugs can be optionally ablated into smaller parts first. The laser ablation can also include an optional method of creating tie bars to provide structural support to the web of circuitry patterns.

A method and arrangement for the texturing of a moving steel strip wherein a texture is applied to a surface of a moving steel strip by ablation by means of a single laser beam or a plurality of laser beams directed at the surface of the moving steel strip and wherein a liquid is supplied on the moving steel strip over a surface area on the moving steel strip that covers the working area of the single laser beam or the plurality of laser beams on the moving steel strip.

Provided are a manufacturing apparatus and a manufacturing method of an electrode for a secondary battery which forms a large number of holes in the electrode mixture having a level difference in thickness, by irradiating twice or less with a nanosecond laser, and an electrode for a secondary battery manufactured by the same.

A laser cutting system for cutting articles, such as tubes, and method of using the same. The laser cutting system can cut slots, holes, and/or pores into each article or tube to form filtration tubes, for example. The system includes a delivery system for delivering a laser beam from a laser source, at least one mirror, a focusing objective lens, a gas source, and a delivery nozzle. A first stage holds each article in a longitudinal direction, and may rotate the article axially during delivery of the gas and laser beam towards the article and move the article longitudinally relative to the delivery nozzle. A second stage is provided in the system for moving the delivery nozzle relative to the article being held by the first stage. A controller controls actuation of the laser beam and the gas source, and movement of the first stage and the second stage.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.
