“…Alternatively, silicon based anodes exhibit great potential due to high Si‐abundance, reasonable electrochemical potential (0.4 V vs Li/Li + ) and high volumetric energy density (2190 mAh cm −3 for the lithiated Li 15 Si 4 phase), which makes them favorable in terms of costs and energy requirements. [ 4 ] However, silicon anodes undergo severe mechanical degradations, due to their huge volume expansion (contraction) (±320%) upon (de‐)lithiation. This volume fluctuation generates a vulnerable silicon surface every cycle exposing to liquid electrolyte, resulting in rapid capacity decay and poor cyclic life due to continuous solid electrolyte interphase (SEI) formation.…”

All‐solid‐state batteries (ASSBs) with silicon anodes are promising candidates to overcome energy limitations of conventional lithium‐ion batteries. However, silicon undergoes severe volume changes during cycling leading to rapid degradation. In this study, a columnar silicon anode (col‐Si) fabricated by a scalable physical vapor deposition process (PVD) is integrated in all‐solid‐state batteries based on argyrodite‐type electrolyte (Li6PS5Cl, 3 mS cm−1) and Ni‐rich layered oxide cathodes (LiNi0.9Co0.05Mn0.05O2, NCM) with a high specific capacity (210 mAh g−1). The column structure exhibits a 1D breathing mechanism similar to lithium, which preserves the interface toward the electrolyte. Stable cycling is demonstrated for more than 100 cycles with a high coulombic efficiency (CE) of 99.7–99.9% in full cells with industrially relevant areal loadings of 3.5 mAh cm−2, which is the highest value reported so far for ASSB full cells with silicon anodes. Impedance spectroscopy revealed that anode resistance is drastically reduced after first lithiation, which allows high charging currents of 0.9 mA cm−2 at room temperature without the occurrence of dendrites and short circuits. Finally, in‐operando monitoring of pouch cells gave valuable insights into the breathing behavior of the solid‐state cell.

“…Lithium‐ion batteries (LIBs) are getting increased attention owing to their special advantages, such as excellent chemical stability, wonderful energy density, and outstanding reliability – . Unfortunately, the dominant electrode materials for commercial LIBs anodes are carbon materials, failing to meet the robust demand for large scale applications which need large energy density and high power density . Particularly, NiCo 2 O 4 , as a transition metal oxide and spinel bimetallic oxide, has been considered as one of the most potential anode materials as its natural abundance, high specific capacity and low environmental impact, more importantly, its feasible oxidation state and high electrical conductivity.…”

A novel structure of "sea urchin-like" NiCo 2 O 4 particles coated with a PPy protection layer is successfully synthesized via a hydrothermal method combined with a subsequent in situ polymerization. As a potential anode material for Li-ion batteries, the as-prepared NiCo 2 O 4 @PPy nanocomposite exhibits a high initial discharge capacity of 1524.1 mAh·g −1 and still maintains a wonderful reversible capacity of 955.6 mAh·g −1 over 100 cycles at a current density of 100 mA·g −1 , and it also delivers a very stable reversible capacity of 541 mAh·g −1 even at a high current density up to 1000 mA·g −1 . The excellent cyclability and rate capability of the composite might be ascribed to the unique architecture of NiCo 2 O 4 particles, especially for the in situ polymerized PPy conductive protection layers, which not only promote the anode material's conductivity, but also protect the inner NiCo 2 O 4 particles from mechanical damage in the process of discharging and charging. The present work indicates that PPy modification could be an effective direction to improve the electrochemical properties of anode with poor conductivity.

“…The anodes composed of Si deposited onto the current collector exhibit a simpler architecture enabling a more detailed investigation, as well as a rational electrode development [23][24][25]. Additionally, Si-based thin film anodes are used for the conception of integrated devices such as microbatteries [26][27][28][29]. However, nanometric thin films have a small areal capacity that is found within a range of several hundred µAh cm −2 .…”

The currently preferred manufacturing method for Lithium-ion battery (LIB) electrodes is via the slurry route. While such an approach is appealing, the complexity of the electrode layers containing the active materials, conductivity helpers, and binders, has hampered detailed investigations of the active materials. As an alternative, an active material can be deposited as a thin film on a planar substrate, which enables a more robust and detailed analysis. However, due to the small areal capacity of nanometric thin films, the electrochemical activity of the cell casing must be negligible or at least well determined. We reported on the capacity and the differential capacity metrics of several materials used in the construction of the electrical terminals in LIBs. Among these materials, Ti was revealed to have the minimum reversible capacity for lithium-ion storage. The mechanical and electrochemical properties of the Ti–based materials were further improved through surface nitridation with thermal treatment in an ammonia-rich atmosphere. The nitridated Ti electrical terminal achieved a reversible capacity that was at least fifteen times lower than that of stainless steel, with a featureless differential capacity representation creating quasi-ideal experimental conditions for a detailed investigation of electroactive thin films.
