Concentrated Electrolytes Widen the Operating Temperature Range of Lithium‐Ion Batteries (Adv. Sci. 18/2021)

Lithium‐Ion Batteries In article number 2101646, Jianhui Wang, Atsuo Yamada and co‐workers report salt‐concentrated electrolytes can overcome various challenges for lithium‐ion full cells that operate in a wide temperature range from ‐20 to 100 °C. This achievement contributes to building a novel power battery pack that requires no thermal management system and deliveries greatly enhanced systematic energy densities in both gravimetry and volumetry.
