Magnesium Alloy Process Developments and Applications

2021/1/28Editor's Note: Although the focused patent surveys in Light Metal Age have generally covered select aluminum technologies, magnesium alloy technology has generally been sidelined. Nevertheless, magnesium is a major alloying master alloy in aluminum casthouse production and critical to the reduction of light metals, such as titanium and beryllium. Therefore, this patent survey aims to []

Cathode

A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena.

Bipolar Electrodes for Next‐Generation Rechargeable

For example, the first commercial lithium‐ion battery (LIB) was assembled by LiCoO 2 cathode and graphite anode. Despite of using identical materials as before, the engineers have successfully increased the energy density of such a LIB to 200 Wh kg −1 from an initial 80 Wh kg −1 through substantial optimizations in cell configurations. [ 5 ]

Pre‐Lithiation Strategies for Next‐Generation Practical

The LiH can react with anode materials (e.g., Si) to obtain lithiated anode and the side‐products are hydrogen gas, which will be exposed to air with further treatment. [ 71 ] The lithiated anode obtained from the abovementioned methods is relatively sensitive to the environment so that it is difficult to prepare electrodes on a large scale based on these materials.

Electroplating

Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block
