Query: Non-Markovian effects on charging and self-discharging processes of
  quantum batteries   The performance of quantum technologies that use entanglement and coherence
as resource is highly limited by decohering effects due to their interaction
with some environment. Particularly, it is important to take into account
situations where such devices unavoidably interact with a surrounding. Here, we
study memory effects on energy and ergotropy of quantum batteries in the
framework of open system dynamics, where the battery and charger are
individually allowed to access a bosonic environment. Our investigation shows
that the battery can be fully charged and its energy can be preserved for long
times in non-Markovian dynamics compared with Markovian dynamics. In addition,
the total stored energy can be completely extracted as work and discharge time
becomes more longer as non-Markovianity increases. Our results indicate that
memory effects can play a significant role in improving the performance of
quantum batteries.
