Fundamental Understanding and Quantification of Capacity Losses
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

Why were rechargeable lithium-anode batteries rejected?
However, the use of lithium metal as anode material in rechargeable batteries was finally rejected due to safety reasons. What caused the fall in the application of rechargeable lithium-anode batteries is also well known and analogous to the origin of the lack of zinc anode rechargeable batteries.
Do electrode defects affect the performance of lithium-ion batteries?
Criteria for quality control: The influence of electrode defects on the performance of lithium-ion batteries is reviewed. Point and line defects as well as inhomogeneities in microstructure and composition and metallic impurities are addressed.
Can lithium cobaltate be replaced with a positive electrode?
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
What happens if a spinel reacts with lithium in electrochemical cells?
On the other hand, the reaction of the spinel with lithium in electrochemical cells leads to a non-crystalline product by transition metal reduction. The products of reaction have been studied by ex situ XRD of the discharged electrodes.
Why should a negative electrode be mixed with graphite?
Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge. In order to avoid this problem, mixing with graphite has favorable effects.
Is lithium a good negative electrode material for rechargeable batteries?
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
