NEGs applications in batteries, whose energy storing mechanisms relies on chemical energy, serve two different, but essential purposes.
In Na-S batteries NEG materials are used to maintain the purity of the reactants in the battery cells, thus guaranteeing a longer life.
In Ni-MH rechargeable batteries a specially-developed getter material, which does not require any activation treatment, is used to remove the hydrogen generated in the recharging process that may pose a safety hazard.
A specific technology that benefits from the distinct features of gettering materials is that of Flywheels. In these devices a rotor is kept spinning at high speed, storing kinetic energy that can be converted into electricity when needed. Vacuum is essential to minimize the drag on the rotor and therefore to limit unwanted energy dissipation. Non-Evaporable Getters or other sorption materials are ideal solutions for the pumping of such devices; they offer a passive and maintenance-free vacuum solution that can last for the lifetime of the Flywheel itself.
