Diminishing the loss of performance of lithium ion batteries (LIBs) is a challenge that is yet to be fulfilled. Understanding of deterioration processes and mechanisms (i.e., so-called aging) requires analytically accurate examination of aged cells.

The accuracy for positional alignment of the positive electrode vs. the negative electrode is of great importance for the quality of assembly of lithium ion cells. Area-oversized negative electrodes increase the tolerance for electrode alignment. In

A P2-type Na0.67Mn0.8Cu0.1Mg0.1O2 has been synthesized as a cathode material for sodium ion batteries. By utilizing the synergetic effects of Cu and Mg substitution, the prepared material delivers a discharge capacity of 84 mAh g−1 at 180 mA g−1,
