ENPOLITE: Comparing Lithium-Ion Cells across Energy, Power, Lifetime, and Temperature

Dechent, Philipp; Epp, Alexander; Jost, Dominik; Preger, Yuliya; Attia, Peter M.; Li, Weihan; Sauer, Dirk U.

Due to their impressive energy density, power density, lifetime, and cost, lithium-ion batteries have become the most important electrochemical storage system, with applications including consumer electronics, electric vehicles, and stationary energy storage. However, each application has unique, often conflicting product specifications, requiring a balanced overall assessment. The Ragone plot is a commonly-used plot to compare energy and power of lithium-ion battery chemistries. Important parameters including cost, lifetime, and temperature sensitivity are not considered. Overall, a standardized and balanced reporting and visualization of specifications would greatly help an informed cell selection process.
