What is a Stored Energy Mechanism (SEM)? | Schneider Electric USA
A Stored Energy Mechanism (SEM) is a mechanism that opens and closes a device (Switch) by compressing and releasing spring energy. The operating handle compresses a set of closing springs and a separate set of opening springs. These springs store the mechanical energy of this movement and are held in the compressed state by close and open latches.

How do chloroaluminate ionic liquids affect the rate of charge storage?
Xu et al. decreased the tortuosity and increased the porosity of graphite cathodes in aluminum batteries with chloroaluminate ionic liquids, yielding higher pseudocapacitive charge storage contributions and thus higher rate-capability. Ultimately, they reduced diffusion paths, δ, and increased mass transport by migration.
