摘要

The key requirements for future high performance battery cells are safe approaches with high energy densities, low cost materials, and kinetic and electrochemical stability upon cycling at high charging rates. [1] All of these properties are the result of complex interplay between the constituent materials for electrodes, electrolytes, coatings, etc. Atomic-scale simulations empower researchers and engineers to rapidly and cost-effectively explore and inspect existing materials and to propose new materials that meet the key requirements. Building on our rich industrial research portfolio, we illustrate practical applications of atomic-scale simulations to investigate materials for all solid-state batteries (ASSB) which utilize solid electrolytes. [2] One application is the screening of materials to design high energy density cathodes with low volume change upon cycling. [3] In another application we discuss the redox reactions of solid electrolytes and electrodes upon charging and discharging, the formation of related phases, and their impact on transport of charge carriers across interfaces. The company Materials Design develops the software environment MedeA? [4] integrating best simulation approaches at the atomic-scale with comprehensive databases, efficient computing and analysis tools and utilities to convert computed data into new material formulations.

[4]将原子级的最佳模拟方法与全面的数据库,有效的计算和分析工具以及实用程序集成在一起,以将计算的数据转换为新的材料配方。
