  The unusual asymptotic structure of the accelerating black holes led to
ambiguity in their geometric characteristics and thermodynamic behavior.
Motivated by the interesting properties of such black holes and the significant
role of electric charge and string tension on their structure, we study the
thermodynamic behavior of these black holes by two methods and examine the
changes of free parameters on the thermal behavior of the black holes. First,
we investigate phase transition and thermal stability of the system through the
use of heat capacity in the non-extended phase space. We examine the effects of
electric charge, string tension and the cosmological constant on the phase
transition and stability of the system. We also find that to have a phase
transition, we have to apply some constraints on the free parameters. Then, we
employ the geometrical thermodynamic (GT) method to study phase transition and
compare the obtained results with those of the heat capacity. Next, we work in
the extended phase space by considering the cosmological constant as a
dynamical pressure and evaluate the existence of van der Waals like phase
transition. We obtain critical quantities and study the effective role of
electric charge and string tension on these quantities. Finally, we make use of
the GT method in the extended phase space and find that the results of the GT
method, heat capacity and $P-V$ diagram lead to a consistent conclusion.
