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.

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.

Argonne boosts silicon anode performance in lithium-ion batteries with new electrolyte mixture

Fri, 10/11/2019 - 10:44 -- Paul Crompton

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed an electrolyte mixture and additive they claim boosts the energy density of next generation lithium-ion batteries by up to 50%. 

To develop its electrolyte additive the scientists added small amount of a second salt containing doubly or triply charged metal cations magnesium (Mg2+), calcium (Ca2+), zinc (Zn2+), or aluminium (Al3+). 

Image by Argonne National Laboratory: shows charging results in doubly or triply charged metal cations, such as Mg2+ (orange spheres), along with singly charged lithium ions (green spheres) being co-inserted from the electrolyte into the silicon (blue spheres) anode material. This process stabilises the anode, enabling long term cycling of lithium-ion batteries.

Scientists double output of flow batteries by revisiting old research

Scientists at the University of Colorado Boulder have devised redox flow battery electrolyte that could double the performance capabilities of traditional variants of the technology.

The team used chromium and organic binding agents to achieve ‘exceptional voltage and high efficiencies’ of 100% current efficiency and an 80% round-trip energy efficiency. The results were published in the journal Joule.
