(Phys.org)—A new semiliquid battery developed by researchers at The
University of Texas at Austin has exhibited encouraging early
results, encompassing many of the features desired in a
state-of-the-art energy-storage device. In particular, the new
battery has a working voltage similar to that of a lithium-ion
battery, a power density comparable to that of a supercapacitor, and
it can maintain its good performance even when being charged and
discharged at very high rates.

The researchers, led by Assistant Professor Guihua Yu, along with Yu
Ding and Yu Zhao, at UT Austin, have published their paper on the new
membrane-free, semiliquid battery in a recent issue of Nano Letters.
The researchers explain that the battery is considered "semiliquid"
because it uses a liquid ferrocene electrolyte, a liquid cathode, and
a solid lithium anode.

"The greatest significance of our work is that we have designed a
semiliquid battery based on a new chemistry," Yu told Phys.org. "The
battery shows excellent rate capability that can be fully charged or
discharged almost within one minute while maintaining good energy
efficiency and reasonable energy density, representing a promising
prototype liquid redox battery with both high energy density and
power density for energy storage."

The battery is designed for applications in two of the biggest areas
of battery technology: hybrid electric vehicles and energy storage
for renewable energy resources.
