Fast Ion Conductor

New battery developed by researchers in US could provide "thousand mile" range for EVs and open up new possibilities for long-haul transport and electric planes.

For the electric vehicle takeover, batteries need a major makeover.

New battery material offers promise for the development of all-solid batteries. In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flamma

Researchers at Tokyo Tech have discovered hidden chemical order of the Mo and Nb atoms in disordered Ba7Nb4MoO20, by combining state-of-the-art techniques, including resonant X-ray diffraction and solid-state nuclear magnetic resonance. This study provides valuable insights into how a material's properties, such as ionic conduction, can be heavily influenced by its hidden chemical order. These results would…

Two Chicago-area institutions teamed up to develop a solid-state battery that could eventually power airplanes.

Many owners of electric cars have wished for a battery pack that could power their vehicle for more than a thousand miles on a single charge. Researchers at the Illinois Institute of Technology (IIT) and U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a lithium-air battery that could make that dream a reality. The team's new battery design could also one day power domestic airplanes and…

We always knew they'd power the EV revolution ... if we ever learned why they short circuit. Mission accomplished.

Garnet-type solid electrolytes are attracting great interest due to high ionic conductivity and excellent electrochemical stability against Li metal. However, the thick electrolyte layer and rigid nature as well as poor interfacial contact are huge obstacles for its application in all-solid-state lithium batteries. Currently, researchers in China provide a promising strategy toward realizing 20 μm-thick flexible…

Solid-state batteries for electric vehicles, offering greater energy density and range than contemporary lithium-ion batteries, remain out of reach, not least due to challenges coming from the composition of the battery's cathode. A new cathode composition and accompanying manufacturing technique looks set to overcome this hurdle.

Google DeepMind's AI breakthrough increases the number of known stable materials by a factor of ten.

In a study published in the journal Science China Chemistry, fluorinated cyclic carbonate (DFEC) was introduced into ether electrolyte as a SEI-forming additive. The modified electrolyte could improve the interface of Li metal anode and achieve high efficiency and long cycling stability of LMBs.

A research team at the Technical University of Munich (TUM) has discovered a material class with above-average conductivity. This is a decisive step forward in the development of high-performance solid-state batteries. Investigations conducted at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) made an essential contribution to the discovery.

A new discovery could finally usher the development of solid-state lithium batteries, which would be more lightweight, compact, and safe than current lithium batteries. The growth of metallic filaments called dendrites within the solid electrolyte has been a longstanding obstacle, but the new study explains how dendrites form and how to divert them.

Scientists have created a chlorine-based solid-state electrolyte for lithium-ion batteries that offers improved performance.

Engineers from MIT and Kyushu University in Japan have demonstrated for the first time that light can be used to significantly improve the performance of fuel cells, lithium batteries and other devices that are based on the movement of charged atoms, or ions.

Electric vehicles may finally be on the cusp of unlocking up to 1,000 miles of range and faster charging speeds, through solid-state battery tech.

A team of European researchers from Helmholtz-Zentrum Berlin (HZB) and Humboldt University in Berlin developed an alternative charging solution to make li-ion batteries last much longer than...

Batteries containing solid electrolytes have many theoretical benefits, but a technique to manufacture them cheaply has been elusive

Recently there was a thread about a "breakthrough" in battery technology at Toyota.https://news.ycombinator.com/item?id=36585327Toyota has been putting out PR puff pieces about their "solid-state" (solid-electrolyte) batteries for years, but this story was unique in that it had a quote from Keiji Kaita, who holds some high-level role at Toyota. Anyway, I didn't think much of it, because there was no paper…

A research group of the Department of Electrical and Electronic Information Engineering at Toyohashi University of Technology—consisting of Hirotada Gamo, a doctoral course student; Kazuhiro Hikima, assistant professor; and Atsunori Matsuda, professor—has elucidated the decomposition behavior of electrolytes in the cathode composites of all-solid-state lithium-sulfur batteries (ASSLSB).
