Today’s lithium-ion batteries fall short of meeting consumers’ needs in the automotive, consumer electronics, and stationary storage sectors. Solid-state lithium-metal batteries have the potential to help bridge this gap, particularly in the automotive sector, because the technology is designed to enable longer range, faster charging and enhanced safety compared to conventional lithium-ion batteries. QuantumScape’s Vice President of Cathode, Cheng-Chieh Chao, will highlight recent developments in solid-state lithium-metal battery technology for automotive applications and discuss innovative commercialization strategies,  like using licensing models,  that are gearing up to get this technology on the road as quickly and cost effectively as possible.

All solid-state Li-metal batteries are the focus of extensive research activities given their perceived potential to meet the safety requirements of advanced applications. With the absence of liquids, these batteries are often considered safer and non-flammable. However, we will discuss a concerning area that has been largely overlooked regarding the exothermic reactivity of Li metal when in contact with standard cathode materials.

Electrochemical stability of an anode-free all solid-state battery (AF-ASSB) based on argyrodite Li6PS5Cl (LPSCl) requires control of two distinct solid electrolyte interphases, SEI-1 and SEI-2. In fact, there are three active interfaces when an "empty" current collector is employed; lithium metal - SE interphase (SEI-1), lithium - current collector interface, and the collector - SE interphase (SEI-2) where copper sulfides are formed. A bilayer of 140 nm magnesium / 30 nm tungsten (Mg/W-Cu) controls these interfaces and allows for state-of-the-art electrochemical performance in half-cells and full cells. An AF-ASSB with NMC811 cathode achieves 150 cycles with Coulombic efficiency (CE) above 99.8%. With a high mass-loading cathode (8.6 mAh cm-2), the AF-ASSB retains 86.5% capacity after 45 cycles at 0.2C. During electrodeposition of Li, a gradient Li-Mg solid solution is formed, which reverses upon electrodissolution. This promotes conformal wetting/dewetting by the Li and stabilizes SEI-1 by lowering the thermodynamic driving force for SE reduction. The refractory W underlayer is required to prevent ongoing formation of SEI-2, which also drives electrochemical degradation. A mechanistic explanation for the observed Li segregation within the alloying LixMg layer is provided through mesoscale modelling, considering the role of diffusivity differences and of interfacial stress.

Furthermore, the composite electrolyte shows stability with Li-metal anodes and greatly improved dendrite resistance due to a desirable combination of ion-transport and rheological properties.
