Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process. . …

Researchers develop real-time picture of formation of solid–electrolyte interphase of a Li-ion battery

Green Car Congress

During the first charging process of a new Li-ion battery cell, trace amounts of electrolyte components decompose sacrificially to form what is called a solid–electrolyte interphase (SEI) on the anode surface. The inner SEI is continuous, dense and impermeable to electrolytes, and it is most probably composed of Li 2 O.

Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. Recently, there has been much interest in the development of electronic and energy storage devices using paper and textile components.

Simple process transforms PET plastic into a nanomaterial for supercapacitors

Green Car Congress

UC Riverside (UCR) engineers have developed a way to recycle PET (polyethylene terephthalate) plastic waste, such as soda or water bottles, into a nanomaterial useful for energy storage. An open-access paper on the work is published in the journal Energy Storage. Mihri Ozkan & Cengiz Ozkan/UCR).
