A battery management system (BMS) is needed for the use of Li-Ion cells. The BMS is indispensable because Li-Ion cells can be dangerous. If overcharged, they can undergo thermal runaway and explode. If overly discharged, chemical reactions take place within the cell that permanently affect its ability to hold charge.

As a function of irradiation time, the unit cell volume undergoes a reduction-to-expansion transition as the AFE phase evolves into FE monoclinic (FE M) and rhombohedral (FE R) phases ( Figure 7 a–e). During the in situ energy storage process, an intermediate transient FD phase was observed between the AFE and FE phases.
