Thick electrodes whose active materials have high areal density may improve the energy densities of lithium-ion batteries. However, the weakened rate abilities and cycle lifetimes of such electrodes significantly limit their practical applications.
e) Charge–discharge voltage profiles and f) energy density analysis of the cell with ten layers of cathode-separator assemblies, cycled at 0.5 mA cm −2. We utilized this multilayered structure for a lithium metal battery, as shown in Figure 5d.
This lithium metal battery can achieve an areal capacity of ≈30 mAh cm −2 and an enhanced energy density of over 20% compared to conventional battery configurations. Lithium-ion batteries, which utilize the reversible electrochemical reaction of materials, are currently being used as indispensable energy storage devices.
Meanwhile, the abundant lithium ions in the separator located between the electrode layers could mitigate the depletion of lithium ions in the ten-layered electrode (Figure S19, Supporting Information). Therefore, most of the active material particles could participate in achieving the high capacity due to the smooth supply of lithium ions.
In this work, the effect of various gradient electrodes on the electrochemical performance of Li-ion batteries was investigated both theoretically and experimentally. A modified 2D model was developed to investigate the effects of different electrode structures on the lithiation process.
Furthermore, it is noted that the wet coating process is a fabrication method that has been adopted for mass production of electrodes in lithium-ion battery manufacturing, and thus the process compatibility for forming the electrode-separator assembly is expected to be superior.

To reveal the aging mechanism, the differential voltage (DV) curves and the variation rule of 10 s internal resistance at different aging stages of the batteries are analyzed. Finally, the aging mechanism of the whole life cycle for LIBs at low temperatures is revealed from both thermodynamic and kinetic perspectives.

First, we summarize the main aging mechanisms in lithium-ion batteries. Next, empirical modeling techniques are reviewed, followed by the current challenges and future trends, and a conclusion. Our results indicate that the effect of stress factors is easily oversimplified, and their correlations are often not taken into account.
Differential voltage analysis and correlation analysis demonstrate that the loss of lithium inventory dominates the aging process, while the accelerated decay rate in the later stage is associated with the loss of active positive electrode material and a significant increase in the internal resistance of the battery.
