Ampcera a step closer to commercialising its solid electrolyte technology for solid-state lithium-ion batteries

Thu, 07/02/2020 - 12:59 -- Paul Crompton

Battery electrolyte developer Ampcera has announced the latest step in the commercialisation of its flexible solid electrolyte (SE) membrane technology for solid-state lithium-ion batteries. 

The US firm claims its solid-state electrolyte (SSE) has the potential to enable solid-state lithium metal batteries to achieve an energy density of 500Wh/kg while reducing cost to below $100/kWh.

New electrolyte developed at Stanford may boost lithium metal batteries

Tue, 06/23/2020 - 18:41 -- Paul Crompton

Scientists at Stanford University have revealed a novel electrolyte design they claim will boost the performance of lithium metal batteries.

The team from the US institution added fluorine atoms onto the electrolyte molecule to make the liquid more stable and create a new molecule that allows the lithium metal anode to function well in the electrolyte.

Call for lithium-ion battery transport loophole to be closed after battery blaze

Tue, 06/09/2020 - 15:06 -- Paul Crompton

The National Transportation Safety Board (NTSB) is calling for a safety loophole to be closed after a fire destroyed a truck transporting large format lithium-ion batteries.

Recommendations by the independent US government agency responsible for investigating civil transportation have been made to address “gaps in the existing regulations” uncovered during the inquiry into the fire in Canada.

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.
