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

Green Car Congress

In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. C, the anode made with bumpy nanospheres was still rechargeable, and during discharge, released nearly 100% of the charge put into the battery.

Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions. —Liu et al.

RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Ce 0.02 (PO 4 ) 3 /C) measured at comparable current densities has been included for comparison. Researchers at Rensselaer Polytechnic Institute have developed a safe, extended cycling lithium-metal electrode for rechargeable Li-ion batteries by entrapping lithium metal within a porous graphene network (Li-PGN).

UT Austin team develops new family of high-capacity anode materials: Interdigitated Eutectic Alloys

Green Car Congress

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a new family of anode materials that can double the charge capacity of lithium-ion battery anodes. It is a simple, low-cost approach that can be applied to a broad range of alloy systems with various working ions such as Li, Na, or Mg.

Stretchable Batteries Make Flexible Electronics More So

Cars That Think

—James Pikul, University of Wisconsin, Madison Djenizian is part of a group that published a paper in February in the journal Advanced Materials Technologies on a stretchable lithium-ion wire battery. The battery is not rechargeable, and its applications include medical patches and hearing aids.
