Increasing the specific energy, energy density, specific power, energy efficiency and energy retention of electrochemical storage devices are major incentives for the development of all-solid-state batteries. However, a general evaluation of all-solid-state battery performance is often difficult to derive from published reports, mostly due to the interdependence of performance measures, but also due to the lack of a basic reference system. Here, we present all-solid-state batteries reduced to the bare minimum of compounds, containing only a lithium metal anode, β-Li₃PS₄ solid electrolyte and Li(Ni_0.6Co_0.2Mn_0.2)O₂ cathode active material. We use this minimalistic system to benchmark the performance of all-solid-state batteries. In a Ragone-type graph, we compare literature data for thiophosphate-, oxide-, phosphate- and polymer-based all-solid-state batteries with our minimalistic cell. Using fundamental equations for key performance parameters, we identify research targets towards high energy, high power and practical all-solid-state batteries.

增加电化学存储设备的比能，能量密度，比功率，能效和能量保持力是开发全固态电池的主要动力。但是，通常很难从已发布的报告中获得对全固态电池性能的一般评估，这主要是由于性能指标之间的相互依赖性，而且还由于缺乏基本的参考系统。这里，我们提出的全固态电池减少到化合物的最低限度的，只包含锂金属的阳极，β-栗₃ PS ₄的固体电解质和锂（镍_0.6钴_0.2锰_0.2）O ₂正极活性物质。我们使用这种简约系统来对所有固态电池的性能进行基准测试。在Ragone型图中，我们将硫代磷酸酯，氧化物，磷酸盐和聚合物基全固态电池的文献数据与我们的简约电池进行了比较。使用关键性能参数的基本方程式，我们确定了针对高能量，高功率和实用的全固态电池的研究目标。
