It depends actually. In general, these are called standard 19-inch instrument racks or cabinets. A rack is merely a set of rails, but a cabinet is included on the sides, open to the front for equipment placements, and typically has a door on the rear to control airflow, and often also has a door on the front to control airflow and also to control access.
Common electrolytes utilized in lithium-ion batteries, most often carbonates, cause dysfunctionality in magnesium ion systems by forming an impermeable layer of deposited electrolytes, which disables magnesium ion transfer.22 Extensive research is underway to establish ideal material combinations for high-quality magnesium-ion batteries.
$begingroup$ My best guess is because these are the easiest to work with metals with low x-ray emission energy. The other choices are Li, Be and Na. For all I know Lithium and Sodium probably have an awfully high vapor pressure in vacuum and low melting point and would contaminate the entire vacuum system (that happened to a fellow student of mine once).
Beyond being cheaper, magnesium-based batteries would also be safer. Poorly made lithium batteries can overheat and explode, creating a liability for industries ranging from telecom to aerospace.
