Areal Capacity

Solid-state batteries (SSBs) with lithium metal anodes offer higher specific energy than conventional lithium-ion batteries, but they must utilize areal capacities >3 mAh cm-2 and cycle at current densities >3 mA cm-2 to achieve commercial viability. Substantial research effort has focused on increasing rate capabilities of SSBs by mitigating detrimental processes such as lithium filament penetration. Less attention has been paid to understanding how areal capacity impacts plating/stripping behavior, despite the importance of areal capacity for achieving high specific energy. Here, we investigate and quantify the relationships among areal capacity, current density, and plating/stripping stability using both symmetric and full-cell configurations with a sulfide solid-state electrolyte (Li6PS5Cl). We show that unstable deposition and short circuiting readily occur at rates much lower than the measured critical current density when a sufficient areal capacity is passed. A systematic study of continuous plating under different electrochemical conditions reveals average “threshold capacity” values at different current densities, beyond which short circuiting occurs. Cycling cells below this threshold capacity significantly enhances cell lifetime, enabling stable symmetric cell cycling at 2.2 mA cm-2 without short circuiting. Finally, we show that full cells also exhibit threshold capacity behavior, but they tend to short circuit at lower current densities and areal capacities. Our results quantify the effects of transferred capacity and demonstrate the importance of using realistic areal capacities in experiments to develop viable solid-state batteries.

<p>Solid-state batteries (SSBs) with alkali metal anodes hold great promise as energetically dense and safe alternatives to conventional Li-ion cells. Whilst, in principle, SSBs have the additional advantage of offering virtually unlimited plating current densities, fast charges have so far only been achieved through sophisticated interface engineering strategies. Here, we reveal that such interface engineering can be easily achieved by tuning the chemistry of NaSICON solid electrolytes (Na<sub>3.4</sub>Zr<sub>2</sub>Si<sub>2.4</sub>P<sub>0.6</sub>O<sub>12</sub>) and taking advantage of the thermodynamic stabilization of a Na<sub>3</sub>PO<sub>4</sub> layer on their surface upon thermal activation. The optimized planar Na|NZSP interfaces are characterized by their exceptionally low interface resistances (down to 0.1 Ω cm<sup>2 </sup>at room temperature) and, more importantly, by their tolerance to large plating current densities (up to 10 mA cm<sup>-2</sup>) even for extended cycling periods of 30 minutes (corresponding to an areal capacity 5 mAh cm<sup>-2</sup>).</p>
