What is a dual-graphite battery (DGB)?

A special case of the DIB is the so-called “dual-graphite battery” (DGB) or “dual-carbon battery” (DCB), in which both the anode and cathode consist of graphite/carbon (Figure 2 B). These DBG or DCB systems are the most promising options when considering sustainability and element abundance aspects, as well as their recycling ability.

What is a dual-ion battery (Dib)?

What are the safety characteristics of battery cells?

In general, the safety characteristics of battery cells can be described by the so-called “fire triangle,” as the combustion of materials and a corresponding fire require three elements, i.e., heat, fuel, and oxygen. If one of these elements can be “removed,” the fire can be extinguished or even be prevented.
