The flexibility of VOLTA allows for its implementation to novel chemical spaces, too. Let us consider a battery system powering an autonomous sensor like an internet of things (IoT) device. Such devices are meant to be wireless and with low to zero maintenance requirements, since electronics have gradually reduced their nominal voltage to about 1.2 V, to decrease dissipation and consumption, and the trend is expected to continue, and reach 0.5 V. Low voltage batteries hence become useful to power them avoiding DC-DC voltage converters.
