“…The model shows good agreement with experimental data from Ecker et al 51 as not only an SEI growth due to non-ideal insulation properties and re-formation after cyclic cracking but also a cathode dissolution reaction is implemented. With this cathodic aging mechanism, the transition to non-linear behavior in retrievable capacity can be explained.…”

“…Therefore, the longer CV phase counterbalances the shorter charging time for the intercalation reaction and does not limit the SEI growth as much as expected. Figure 6 compares the simulated non-linear behavior in usable capacity with experimental results by Ecker et al 51 The non-linearity in usable capacity occurs as soon as the LAM in the cathode becomes larger than the LLI. Whereas the decrease in the beginning of the capacity fade and the position of the transition zone from linear to non-linear aging behavior are in good agreement, the slope after the transition zone is underestimated by the model.…”

“…This is to be expected as the same reduction potential and an overall side reaction exchange current density i 0,SEI is assumed. The incorporation of the two main degradation products is still advisable as it influences the thickness prediction of the SEI by the different molar volumes of LiF and Li 2 51 and data from the proposed model for calendar aging at 50% SOC as a result of SEI formation.…”

In this paper we introduce a pseudo two-dimensional (P2D) model for a common lithium-nickel-cobalt-manganese-oxide versus graphite (NCM/graphite) cell with solid electrolyte interphase (SEI) growth as the dominating capacity fade mechanism on the anode and active material dissolution as the main aging mechanism on the cathode. The SEI implementation considers a growth due to non-ideal insulation properties during calendar as well as cyclic aging and a re-formation after cyclic cracking of the layer during graphite expansion. Additionally, our approach distinguishes between an electronic (σ SEI ) and an ionic (κ SEI ) conductivity of the SEI. This approach introduces the possibility to adapt the model to capacity as well as power fade. Simulation data show good agreement with an experimental aging study for NCM/graphite cells at different temperatures introduced in literature. © The Author Lithium-ion batteries are one of the most promising candidates for energy storage in future stationary storage systems and electric vehicles.1-3 Enormous research efforts have been conducted to get a thorough understanding of the system "lithium-ion cell" and to further develop it for higher energy and power density, higher safety standards as well as longer cycle life. 4 The aging behavior of lithium-ion batteries has been a focus issue of battery research since the introduction of lithium-ion cells by Sony in 1991. 5 Reviews by Agubra et al., 6,7 Arora et al., 8 Aurbach et al., 9,10 Birkl et al., 11 Broussely et al., 12 Verma et al. 13 and Vetter et al. 14 are just a few examples of the extensive literature regarding aging behavior. Commonly accepted and experimentally verified aging phenomena as mentioned in the previously cited literature are electrolyte decomposition leading to solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI) growth, solvent co-intercalation, gas evolution with subsequent cracking of particles, a decrease of accessible surface area and porosity due to SEI growth, contact loss of active material particles due to volume changes during cycling, binder decomposition, current collector corrosion, metallic lithium plating and transition-metal dissolution from the cathode. The listed aging mechanisms can be assigned to three different categories that are a loss of lithium-ions (LLI), an impedance increase and a loss of active material (LAM). 12,[15][16][17][18] The LLI is synonymous to a decrease in the amount of cyclable lithium-ions as they are trapped in a passivating film on either of the electrodes or in plated metallic lithium. Due to the growth of the passivating layers and/or the formation of rock-salt in the cathode (residue of the cathode active material after transition-metal dissolution), kinetic transport of lithium-ions through those inactive areas is limited and results in an impedance rise. An LAM can be caused by the dissolution of transition-metal-ions from the cathode bulk material, changes in the electrode composition and/or changes in crystal structure of the a...

Multiscale Understanding of Surface Structural Effects on High‐Temperature Operational Resiliency of Layered Oxide Cathodes

The worldwide energy demand in electric vehicles and the increasing global temperature have called for development of high‐energy and long‐life lithium‐ion batteries (LIBs) with improved high‐temperature operational resiliency. However, current attention has been mostly focused on cycling aging at elevated temperature, leaving considerable gaps of knowledge in the failure mechanism, and practical control of abusive calendar aging and thermal runaway that are highly related to the eventual operational lifetime and safety performance of LIBs. Herein, using a combination of various in situ synchrotron X‐ray and electron microscopy techniques, a multiscale understanding of surface structure effects involved in regulating the high‐temperature operational tolerance of polycrystalline Ni‐rich layered cathodes is reported. The results collectively show that an ultraconformal poly(3,4‐ethylenedioxythiophene) coating can effectively prevent a LiNi0.8Co0.1Mn0.1O2 cathode from undergoing undesired phase transformation and transition metal dissolution on the surface, atomic displacement, and dislocations within primary particles, intergranular cracking along the grain boundaries within secondary particles, and intensive bulk oxygen release during high state‐of‐charge and high‐temperature aging. The present work highlights the essential role of surface structure controls in overcoming the multiscale degradation pathways of high‐energy battery materials at extreme temperature.
