Query: Quantum battery based on quantum discord at room temperature   The study of advanced quantum devices for energy storage has attracted the
attention of the scientific community in the past few years. Although several
theoretical progresses have been achieved recently, experimental proposals of
platforms operating as quantum batteries under ambient conditions are still
lacking. In this context, this work presents a feasible realization of a
quantum battery in a carboxylate-based metal complex, which can store a finite
amount of extractable work under the form of quantum discord at room
temperature, and recharge by thermalization with a reservoir. Moreover, the
stored work can be evaluated through non-destructive measurements of the
compound's magnetic susceptibility. These results pave the way for the
development of enhanced energy storage platforms through material engineering.
