Lithium-sulfur batteries are emerging as strong contenders in energy storage; however, a cohesive design framework, systematic performance analysis and benchmarks remain absent. This study bridges this gap by examining recent advancements, with a focus on functional sulfur host materials, using a data-driven approach. Through a meticulous literature review, we digitize 866 galvanostatic cycling and rate capability plots, along with the collection of key host material properties-such as specific surface area and polysulfide binding/adsorption energy-as well as essential cell design parameters including sulfur loading, electrode formulation, and electrolyte-to-sulfur ratios, to standardize performance using specific energy and power metrics. This approach enables us mapping field advancements and identify impactful research contributions. Additionally, irrespective of materials chemistry, a comprehensive analysis of this database helps us to disclose general patterns that apply universally across all cells, highlight the most constructive and detrimental regions of the design-parameter space, and perceive potential synergies. These insights outline key areas for optimization, guiding future development of practical lithium-sulfur battery technology.
锂硫电池正成为储能领域强有力的竞争者；然而，目前仍缺乏一个连贯的设计框架、系统的性能分析和基准。本研究通过采用数据驱动的方法，审视近期的进展，重点关注功能性硫主体材料，弥补了这一差距。通过细致的文献综述，我们将866个恒电流循环和倍率性能图数字化，并收集关键主体材料特性（如比表面积和多硫化物结合/吸附能）以及基本的电池设计参数（包括硫负载量、电极配方和电解质与硫的比例），以使用比能量和功率指标来规范性能。这种方法使我们能够描绘该领域的进展并识别有影响力的研究贡献。此外，无论材料化学如何，对该数据库的全面分析有助于我们揭示适用于所有电池的通用模式，突出设计参数空间中最具建设性和最不利的区域，并认识到潜在的协同效应。这些见解勾勒出优化的关键领域，为实用锂硫电池技术的未来发展提供指导。
