The prototypes have much longer cycling lives than a typical lithium-sulfur battery.
that's produced at half the cost of lithium-ion ones, it seems there is always something new and exciting happening in the field.ngineers at the University of California, San Diego, have engineered novel energy-packed lithium-ion batteries that perform optimally at freezing cold and scorching hot temperatures,“You need high-temperature operation in areas where the ambient temperature can reach the triple digits and the roads get even hotter.
“Also, batteries warm up just from having a current run through during operation. If the batteries cannot tolerate this warmup at high temperature, their performance will quickly degrade.” Chen's team ran tests with the prototype batteries and found that they retained 87.5% and 115.9% of their energy capacity at -40 and 122 F , respectively. Better yet, the researchers reported that the prototypes had high Coulombic efficiencies of 98.2% and 98.7% at these temperatures, which means the batteries can undergo more charge and discharge cycles before they cease to function.
The end result was batteries with much longer cycling lives than a typical lithium-sulfur battery. “Our electrolyte helps improve both the cathode side and anode side while providing high conductivity and interfacial stability,” said Chen. enable electric vehicles to travel further on a single charge in cold climates while also alleviating the need for cooling systems to keep the vehicles’ battery packs from overheating in hot climates.
