Title:*Collective effects**in quantum batteries*** *
*

_Abstract_

Quantum batteries are quantum devices that allow energy storage. During 
the last years there has been a growing interest in 
understanding whether quantum effects can be used to boost their 
capacity or charging power. In fact, it was shown that for closed 
quantum batteries (isolated from the environment) global operations can 
be used to speed up their power when compared with classical batteries. 
In this talk, I will first focus on dissipative batteries, which are 
batteries that evolve towards an equilibrium state while being coupled 
to a thermal bath. I will discuss how collective effects provide a 
different enhancement in their power and how quantum coherences affect 
their performance.  Finally, I will talk about the significance of 
collective transformations when fluctuations in energy are constrained.
