Abstract:
Organophosphonic acids are highlighted to delaminate cathode materials from Al foil, with an Al leaching rate of only 2.88%. Mechanistic analysis revealed that organophosphonic acids formed a dense passivation layer on the surface of the Al foil, inhibiting the dissolution of the Al foil and reducing the interaction between the Al foil and binder.

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...
