Production method of continuous casting rolled metal strip

Abstract

The invention discloses a production method of a continuous casting rolled metal strip. The production method comprises the following steps: adding a liquid metal into a feeding side of a control roller set; keeping the liquid metal in a liquid state and in a flowable state by means of a high-temperature area arranged on the feeding side of the controller roller set; controlling a forming thickness of the liquid metal by means of the control roller set; and cooling and sizing the liquid metal on a transmission belt to the metal strip by means of a cooling area arranged on a discharging side ofthe control roller set. According to the production method of the continuous casting rolled metal strip, the thickness of the liquid metal is controlled by the control roller set, the liquid metal moves to the cooling area on the discharging side of the control roller set under joint action of the control roller set and the transmission belt, and the metal is cooled and sized by the cooling areato obtain the metal strip. As a result of high flowability of the liquid metal, the thickness of the liquid metal can be controlled very thin. When a compound metal strip is used as an energy-storingelectrode, a using demand can be met.

Description

technical field [0001] The invention relates to a production method of a metal strip, in particular to a production method of a continuous casting and rolling metal strip. Background technique [0002] The negative electrode of the lithium-ion battery is formed by mixing the negative electrode active material carbon material or non-carbon material, binder and additives, and the paste is evenly applied on both sides of the copper foil, dried and rolled. Whether lithium-ion batteries can be successfully manufactured depends on whether anode materials that can reversibly extract / intercalate lithium ions can be prepared. Generally speaking, the selection of a good anode material should follow the following principles: high specific energy; low electrode potential relative to lithium electrodes; good reversibility of charge and discharge reactions; good compatibility with electrolyte and binder; small specific surface area (<10m 2 / g), high true density (>2.0g / cm 3 ); go...

AI Technical Summary

Problems solved by technology

When thick metal lithium strips are used in metal lithium batteries, the capacity of the negative electrode is far greater than that of the positive electrode, which causes waste of lithium metal in the negative electrode, increases the volume and weight of the battery, and reduces the volume and quality of the battery. Energy density is not conducive to the improvement of the limit energy density of metal lithium batteries

In addition, the Chinese patent with the publication number CN105489845A proposes a method based on PVD to prepare a thin-layer metal lithium-based negative electrode. This method can prepare metal lithium with a thinner thickness, but this method cannot be continuously produced in large quantities.
