Operations at extreme temperatures
“High temperature operation is needed in areas where ambient temperatures can reach triple digits and roads get even hotter. In electric vehicles, battery packs are often under the floor near these hot roads,” said Zheng Chen, professor of nanoengineering at the UC San Diego Jacobs School of Engineering and lead author of the study.
“In addition, the batteries heat up only with the passage of current during operation. If the batteries cannot tolerate this high-temperature heating, their performance will quickly degrade.”
Chen’s team tested the prototype batteries and found that they retained 87.5% and 115.9% of their energy capacity at -40 and 122 F (-40 and 50 C), respectively. Better still, the researchers reported that the prototypes had high Coulombic efficiencies of 98.2% and 98.7% at these temperatures, meaning the batteries can undergo more charge-discharge cycles before they stop working.
However, developing the new batteries was no easy task.
“If you want a battery with high energy density, you generally need to use very hard and complicated chemistry,” Chen said. “High energy means more reactions are happening, which means less stability, more degradation. Making a high-energy battery that is stable is a difficult task in itself; trying to do this across a wide temperature range is even more challenging.”
Engineering a dibutyl ether electrolyte
To get around these obstacles, the team invented a dibutyl ether electrolyte and designed the sulfur cathode to be more stable by grafting it onto a polymer that prevents more sulfur from dissolving in the electrolyte.
The end result was batteries with much longer life cycles than a typical lithium-sulfur battery. “Our electrolyte helps improve both the cathode and anode sides while providing high conductivity and interfacial stability,” Chen said.
The new batteries could now allow electric vehicles to travel further on a single charge in cold climates, while alleviating the need for cooling systems to prevent vehicle battery packs from overheating in hot climates. But first, the team needs to scale the battery’s chemistry, optimizing it to run at even higher temperatures and further extend its life cycle.
The study is published in the Proceedings of the National Academy of Sciences (PNAS).
Room temperature operation capability and increased energy density have been recognized as two crucial goals, but are rarely achieved together in rechargeable lithium (Li) batteries. In this paper, we demonstrate an electrolyte system by using monodentate dibutyl ether with low melting points and high boiling points as the sole solvent. Its weak solvation gives it an aggregate solvation structure and low solubility towards polysulfide species at relatively low electrolyte concentration (2 mol L−1). These features were found to be vital in preventing dendrite growth and allowing Li metal Coulombic efficiencies of 99.0%, 98.2%, and 98.7% at 23 °C, −40 °C, and 50 °C, respectively. . Bag cells employing thin Li metal cathodes (50 μm) and high charge sulfurized polyacrylonitrile (3.3 mAh cm−2) (negative to positive capacitance ratio = 2) produce 87.5% and 115, 9% of its capacity at room temperature at −40 °C and 50 °C, respectively. This work provides solvent-based design criteria for a wide range of lithium sulfur pocket cell temperatures.
