For alkali-ion batteries, most non-aqueous electrolytes are unstable at the low electrode potentials of the negative electrode, which is why a passivating layer, known as the solid electrolyte interphase (SEI) layer generally is formed. Ideally, the SEI should be formed during the first cycles under minimum charge consumption to circumvent large irreversible capacity
Active lithium ions provided by the positive electrode will be lost in the negative electrode with the formation of organic/inorganic salts and lithium dendrites, which lead to a mismatch between the positive and negative electrode capacities, and further decrease the capacity of the battery. 20 In addition, the peaks of A are sharper than that of B, meaning the
