When temperatures drop below freezing, mobile phones often need recharging, and electric cars have shorter driving ranges. This is because the anodes of their lithium-ion batteries become sluggish, hold less charge and drain energy quickly. To improve electrical performance in the extreme cold, researchers reporting at ACS Central Science have replaced the traditional graphite anode in a lithium-ion battery with a carbon-based anode material, which maintains its storage capacity. it can be recharged down to -31 F.
Lithium-ion batteries are great for powering rechargeable electronics because they can store a lot of energy and have a long lifespan. But when temperatures fall below freezing, the electrical performance of these energy sources deteriorates, and when conditions are cold enough, they can fail to transfer any charge. This is why some people living in central United States in the United States struggle with their electric cars in the dead of winter, and why it is dangerous to use these batteries when space exploration. Scientists recently determined that a flat graphite orientation at the anode was responsible for the decrease in lithium-ion battery energy storage capacity in the cold. Therefore, Xi Wang, Jianian Yao and colleagues wanted to modify the surface structure of carbon-based material to improve the charge transfer process of the anode.
To create the new material, the researchers heated a cobalt-containing imidazolate zeolite framework (known as ZIF-67) at high temperatures. The resulting 12-sided carbon nanospheres had uneven surfaces that demonstrated excellent electrical charge transfer capabilities. The team then tested the electrical performance of the material as the anode, with lithium metal as the cathode, inside a coin-shaped battery. The anode showed stable charging and discharging at temperatures of 77 F to -4 F and maintained 85.9% of room temperature energy storage capacity just below freezing point. By comparison, lithium-ion batteries made with other carbon anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. When the researchers dropped the air temperature to -31 F, the anode made with uneven nanospheres was still rechargeable, and during discharge, almost 100% of the charge charged in the battery was released. Incorporating the uneven nanosphere material into lithium-ion batteries could open up the possibilities for using these energy sources at very low temperatures, the researchers said.
