Title: Asymmetric Temperature Modulation for Extreme Fast Charging of Lithium-Ion Batteries

Abstract

Adding 200 miles range in 10 minutes, so-called extreme fast charging (XFC), is a key to mainstream adoption of battery electric vehicles (BEVs). Here, we present an asymmetric temperature modulation (ATM) method that, on one hand, charges a Li-ion cell at an elevated temperature of 60oC to eliminate Li plating, and, on the other, limits the exposure time at 60oC to only ~10-min per cycle, or 0.01% of the lifetime of a BEV, to prevent severe solid-electrolyte-interphase growth. The asymmetric temperature between charge and discharge opens a new path to enhance kinetics and transport during charging while still achieving long life. Here, we show that a 9.5-Ah 170-Wh/kg cell sustained 1,700 XFC cycles (6C-charge to 80% state of charge) at 20% capacity loss with the ATM, compared to 60 cycles for a control cell, and that a 209-Wh/kg BEV cell retained 91.7% capacity after 2,500 XFC cycles.
