1. A capacitor-assisted battery module comprising:
a housing;
a positive terminal;
a negative terminal;
one or more capacitor-assisted battery cells disposed in the housing and comprising one or more battery terminals and one or more capacitor terminals, wherein at least one of the one or more battery terminals and the capacitor terminals is connected to the negative terminal; and
one or more first switches configured to connect the one or more capacitor terminals to the positive terminal,
wherein
the positive terminal and the negative terminal are configured to output an overall voltage of the capacitor-assisted battery module, and
one of the one or more capacitor-assisted battery cells comprises at least three terminals, each of which being connected to i) the positive terminal via one of the one or more first switches, ii) the negative terminal, or iii) a terminal of another one of the one or more capacitor-assisted battery cells, wherein one of the at least three terminals is connected to at least one of a) a plurality of capacitor electrodes, and b) a plurality of battery electrodes.
