Recharge systems, definition

Not all systems can be described using these definitions, since there are also combined systems such as metal-air batteries [8-10] which contain a battery electrode (metal anode) and a fuel cell electrode (air cathode), or redox flow batteries [11,12] which are a form of rechargeable battery in which electrolyte containing one... 

In addition, apart from the primary accumulators (which are, by definition, non-rechargeable), all these components instantly facilitate reversible functions in terms of power (charge or discharge) which, unfortunately, are often not symmetrical. This property is of cracial importance for their use in electrical systems. 

In general, the field of alternative anodes for rechargeable Li batteries based on tin alloys is extensive and dynamic, and cannot be covered even briefly in this chapter. However, it is important to mention a unique phenomenon found in these systems that definitely relates to their surface chemistry and the formation of surface films. In recent work by Dahn et al. on Li insertion-deinsertion into SnSi films studied by in situ AFM imaging [181], it was found that after lithium insertion into these films, deinsertion...
