  The advantage of quantum batteries is that quantum resources can be used to
improve charging efficiency. The quantum resources that are known to be
available are: quantum entanglement and quantum coherence. In this paper, we
introduce quantum steering as a new quantum resource into batteries for the
first time. We analyze the relationship between quantum steering, quantum
entanglement, energy storage, and extractable work by considering two models:
Field-quantum battery and Cavity-Heisenberg quantum battery. We find that in
the steerable range, the quantum steering of different qubits has a maximum or
minimum value, which corresponds to the energy storage of the battery, and the
extractable work has a maximum value. The occurrence of the minimum value of
quantum entanglement is always accompanied by the occurrence of the maximum
value of parameters such as energy storage. Ultimately, we analyzed the reasons
for these results using the purity of the system. And found a relatively
general conclusion: when the purity is at the maximum, important parameters
such as the energy storage of the battery are also at the maximum.
