“…The authors of [24,130] investigated the effect of the storage duration, temperature (45-80 ° C), and electrolyte additives on the characteristics of industrial LIB containing negative electrodes prepared from mesocarbon microbeads mixed with mesocarbon fibers. The positive electrodes were fabricated of Li x CoO 2 and the electrolyte was a 1 M LiPF 6 solution in an EC-EMC mixture containing such additives as VC and a lithium organoboron complex (Li-OBC).…”

The phenomenology of the decrease in the capacity and energy density of lithium-ion batteries during their cycling and storage is considered together with the basic factors responsible for this phenomenon (overcharge and self-discharge of batteries, dissolution and phase alterations of electrode materials, cathodic reduction and anodic oxidation of electrolyte components, corrosion of materials of current leads) and the mechanism of chemical and electrochemical electrode processes responsible for degradation of batteries. Possible ways and basic techniques of increasing stability of exploitation characteristics of batteries are considered.

“…It can also react with the electrolyte leading to gas evolution and a surface layer formation on the cathode which results in an impedance rise. 8 All of these degradation mechanisms are enhanced by high charge and discharge rates as well as well as high temperature environments.…”

A commercial lithium-ion cell with LiCoO 2 /graphite electrodes was cycled at high-rates (2C) at room temperature. Periodic measurements were performed including internal pressure measurement, discharge capacity, and electrochemical impedance spectroscopy (EIS). Poor cell cyclability was demonstrated with 39% capacity fade after 250 cycles. Both the pressure rise and capacity fade demonstrated a paralinear behavior that is primarily parabolic in the early stage with a dependency on the square-root of the cycle number, followed by a transition to a linear dependency on cycle number in later cycles. An examination of the pressure and capacity evolution presented a direct correlation indicating a very strong, statistically significant relationship between the two (r s = 0.9455). Post cycling gas-chromatography analysis of the gases detected CO, CO 2 , CH 4 , C 2 H 6 , and C 3 H 8 indicating reactions with trace impurities and a reduction of the electrolyte. Scanning electron microscope (SEM) analysis revealed minimal changes to the surface morphology of the cathode, while demonstrating an ostensible passivation layer buildup as well as crack formations inducing continued electrolyte reduction. EIS analysis indicated an apparent increase in R CT in the early stages, followed by a stronger contribution of the charge-transfer kinetics and Li + transport through the solid-electrolyte interphase (SEI) in later stages.The demand for high power and energy coupled with long cycle life, low cost, and increased safety have become the driving factors in the development of lithium-ion batteries (LIBs). This demand continues to expand with the sustained capability expansion of high power military applications, electric vehicles, grid-tie energy storage, and other renewable energy applications. Unlike the short innovation cycles that technologies like portable electronics experience, these applications are focused on an affordable long-term product lifecycle that is safe. In order to achieve these long-term goals, a better understanding of the chief degradation mechanisms as well as a more sophisticated approach for battery life prediction is needed. The complicated nature of LIB aging poses a challenge to this goal as the power and capacity fade are products of various processes and internal interactions. There has been extensive research aimed at better understanding the stability of various electrode materials, electrolytes, and cell components, however power and capacity fade continue to be a nontrivial impediment to many of these applications. The cause of power and capacity fade of LIBs can generally be grouped into three categories: structural degradation (e.g., volume change, phase transition, and binder decomposition), chemical changes to the electrodes (e.g., chemical decomposition, dissolution reaction), and surface layer formation at the electrode-electrolyte interface. Additionally, current collector corrosion and metallic lithium plating contribute to power and capacity fade. All of these degradation mechanisms will...
