ORNL‘s polymer and ceramic composite promises better solid-state electrolyte for lithium metal batteries

Wed, 05/20/2020 - 10:56 -- paul Crompton

Researchers at Oak Ridge National Laboratory (ORNL) have developed a thin film, highly conductive solid-state electrolyte made of a polymer and ceramic-based composite for lithium metal batteries. 

The electrolyte’s novel design is a three-dimensional interconnected structure that can provide mechanical robustness and high lithium ionic conductivity at room temperature.

Daimler focusing research on designing cobalt and lithium out of lithium-ion batteries

Mon, 05/04/2020 - 15:06 -- paul Crompton

Mercedes-Benz, a subsidiary of Daimler, is researching ways to design cobalt and other “critical” materials like lithium out of lithium-ion batteries.

The German vehicle OEM is looking at a variety of post-lithium-ion batteries— mainly based on manganese— that use less critical resources as it investigates ways of increasing energy density of its technology.

Scientists in China develop high-performance lithium-sulfur battery cathode

Wed, 04/22/2020 - 14:06 -- paul Crompton

Scientists at the Dalian Institute of Chemical Physics (DICP) at the Chinese Academy of Sciences have developed a cathode they claim will increase the performance capabilities of lithium-sulfur batteries.

Teams led by professor Jian Liu (pictured) and professor Zhongshuai Wu have increased the catalytic activity and sulfur loading of lithium-sulfur batteries by using a mesoporous carbon nanoreactor decorated with Fe1-xS electrocatalyst nanoparticles (Fe1-xS-NC) as the cathode.

Researchers use radio frequency to detect health of commercial lithium-ion batteries

Thu, 01/30/2020 - 14:38 -- paul Crompton

Researchers from Sandia National Laboratories have developed a radio-frequency detector that monitors a lithium-ion battery’s health while cycling— a first for commercially available batteries.

Placed inside the battery, the paper-thin magnetic resonance detector could help researchers better understand and characterise batteries to improve them for renewable storage and national security applications.

Solid-state battery breakthrough first stage in doubling energy density of lithium-ion cells

Fri, 11/29/2019 - 09:33 -- paul Crompton

Researchers at Australia's Deakin University have reported a way of using common industrial polymers to create solid electrolytes for solid-state lithium-ion batteries.

The scientists’ new solid polymer electrolyte system, based on a new lithium transport mechanism, was weakly bonded to the lithium-ion to replace the liquid solvents typically used as electrolytes in battery cells.
