<p>Silicon carbon void structures (Si-C) are attractive anode materials for Lithium-ion batteries to cope with the volume changes of silicon during cycling. In this study, Si-C with varying Si contents (28 ‑ 37 %) are evaluated in all-solid-state batteries (ASSBs) for the first time. The carbon matrix enables enhanced performance and lifetime of the Si-C composites compared to bare silicon nanoparticles in half-cells even at high loadings of up to 7.4 mAh cm<sup>-2</sup>. In full cells with nickel-rich NCM (LiNi<sub>0.9</sub>Co<sub>0.05</sub>Mn<sub>0.05</sub>O<sub>2</sub>, 210 mAh g<sup>-1</sup>), kinetic limitations in the anode lead to a lowered voltage plateau compared to NCM half-cells. The solid electrolyte (Li<sub>6</sub>PS<sub>5</sub>Cl, 3 mS cm<sup>-1</sup>) does not penetrate the Si-C void structure resulting in less side reactions and higher initial coulombic efficiency compared to a liquid electrolyte (72.7 % vs. 31.0 %). Investigating the influence of balancing of full cells using 3-electrode ASSB cells revealed a higher delithiation of the cathode as a result of the higher cut-off voltage of the anode at high n/p ratios. During galvanostatic cycling, full cells with either a low or rather high overbalancing of the anode showed the highest capacity retention of up to 87.7 % after 50 cycles. </p>

Optimized Conditions

Current lithium-ion batteries are close to reaching their physicochemical energy density limit. Moreover, they present high operation risks regarding their liquid electrolyte. Solid-state batteries are a promising alternative to overcome these problems. They offer safe operation, and potentially improved energy and power density. The option of operating at higher voltages has led to the possibility of employing high capacity electrodes. In this study, the synthesis of a nanostructured anode through electrospinning was carried out. This electrode is based on polymer nanofibres with intercalated graphite particles. The effect of molecular weight, voltage, temperature and humidity has been studied for the formation of smooth and uniform nanofibres. At the optimized conditions, Polyethylene oxide (PEO)-Polyethylene glycol (PEG) nanofibres with diameters around 600 nm were successfully electrospun. The effect of graphite loading on the electrospinning of this solution was also studied. A 30% graphite particle loading in the final fibres was reached with a reproducible methodology. It was found that the electrospun graphite particles received a polymer coating during electrospinning. EDX analysis confirmed that most of the graphite particles are covered by a polymer layer, confirming this hypothesis. Even if it is unclear how this affects the behaviour of the graphite for energy storage, high graphite content was electrospun together with PEO nanofibres with a new methodology.
