Overview
The Nickel Iron Battery is the primary electrical energy storage device for the GVCS.
Detailed Description
The nickel-iron battery (NiFe battery) or "edison cell" is a storage battery having a nickel oxide-hydroxide cathode and an iron anode, with an electrolyte of potassium hydroxide (lye can be used as a substitute).
The active materials are held in nickel-plated steel tubes or perforated pockets.
It is a very robust battery which is tolerant of abuse, (overcharge, overdischarge, and short-circuiting) and can have very long life even if so treated.
It is often used in backup situations where it can be continuously charged and can last for more than 20 years.
