Battery Scientists at United States Penn State University, believe an all-climate battery is possible, following detailed research. Their work has produced a novel design for a lithium-ion battery, that optimizes performance in extreme climates. This is a most interesting development, especially given the colder winters we are experiencing.
The All-Climate Challenge of Lithium-Ion Batteries
Lithium-ion batteries struggle to achieve their full potential at low temperatures, as evidenced by electric vehicle performance in winter. But the real worry could be the possibility of lithium-ion batteries exploding at high temperatures.
The Penn State research, which we link to below, proposes a design that could address these two challenges at the same time. We are aware of previous efforts in this regard, although these have not addressed high and low temperature issues simultaneously.
We understand that the original design envisaged lithium-ion batteries operating at room temperature. “But now that these batteries have been integrated into electric vehicles, data centers and large-scale systems,” a researcher observes …
“They can run very hot, and a stable operational temperature has become awkward for manufacturers to work around. We need to address this fundamental design flaw to enhance large systems. It would be great if an all-climate battery offered stable and efficient performance over a wider range of temperatures.”
How the Penn State Team Tackled Climate Issues
The scientists at Penn State University imagined a heating element inside a lithium-ion battery, which could support battery operation at low temperatures. This would allow them to concentrate on high temperature issues, without comprising performance in cold climates.
This novel approach combines low temperature management with improving tolerance to high temperatures. The Penn State team plans to adjust the electrodes and electrolyte in current lithium-ion batteries, to allow for a thin sheet of nickel only slightly thicker than a red blood cell.
This, they say will allow a battery system to self-regulate temperature (by presumably heating the nickel sheet when required) while adding virtually no weight or volume to the battery. The team’s longer-term goal is to enable safe operation within the -50 to 75 C (-55 to 165 F) ambient temperature ranges.
