Twelve distinguished speakers will be covering critical topics impacting energy storage and conversion at the upcoming AIP Publishing Horizons Virtual Conference on Aug. 4-6. The three-day event is organized by the journal Applied Physics Reviews and brings together leaders in the field of energy science to present their latest research in six sessions
The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.
A deceptively simple sensor system developed at PNNL can prevent dangerous battery fires.
Researchers at Aalto University have discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.
Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.

Three technologies developed by researchers at Oak Ridge National Laboratory have won National Technology Transfer Awards from the Federal Laboratory Consortium. The annual FLC Awards recognize significant accomplishments in transferring federal laboratory technologies to the marketplace.
Using X-ray tomography, a research team has observed the internal evolution of the materials inside solid-state lithium batteries as they were charged and discharged. Detailed three-dimensional information from the research could help improve the reliability and performance of the batteries, which use solid materials to replace the flammable liquid electrolytes in existing lithium-ion batteries.
Researchers reporting in ACS’ Nano Letters have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.
Taking a look back at the paths taken by the Joint Center for Energy Storage Research.
Lithium-ion batteries that function as high-performance power sources for renewable applications, such as electric vehicles and consumer electronics, require electrodes that deliver high energy density without compromising cell lifetimes. In the Journal of Vacuum Science and Technology A, researchers investigate the origins of degradation in high energy density LIB cathode materials and develop strategies for mitigating those degradation mechanisms and improving LIB performance.
Lawrence Livermore National Laboratory (LLNL), New Energy Nexus and CalCharge are co-hosting the sixth annual Bay Area Battery Summit (BABS), to be held virtually on Nov. 17-18.
Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible energy storage. Research reported in Applied Physics Reviews aims to offer a solution by showing how the inclusion of conductive fillers improves battery performance.
Researchers are developing new ways to advance lithium-rich batteries and using new materials for practical use, according to researchers with the U.S. Department of Energy’s Argonne National Laboratory.
Researchers at Berkeley Lab, in collaboration with Carnegie Mellon University, have developed a new battery material that could enable long-range electric vehicles that can drive for hundreds of miles on a single charge, and electric planes called eVTOLs for fast, environmentally friendly commutes.
An unexpected property of nanometer-scale antimony crystals — the spontaneous formation of hollow structures — could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.
Researchers sped-up the motion of lithium ions in solid-state batteries using the paddlewheel effect.
In the First-Person Science series, scientists describe how they made significant discoveries over years of research. Esther Takeuchi is a professor at Stony Brook University and the director of the Center for Mesoscale Transport Properties, a Department of Energy Office of Science Energy Frontier Research Center.
Story tips from the Department of Energy’s Oak Ridge National Laboratory
A team of researchers has developed a portable, more environmentally friendly method to produce hydrogen peroxide. It could enable hospitals to make their own supply of the disinfectant on demand and at lower cost.
Atomic distortions emerging in the electrode during operation provide a “fast lane” for the transport of lithium ions.
A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries. In Applied Physics Reviews, researchers at the University of Porto and the University of Texas at Austin report making their very simple battery with two different metals, as electrodes and a lithium or sodium glass electrolyte between them.
At a conference held by the ReCell Center, an advanced battery recycling collaboration based at Argonne, representatives from industry, government, and academia discussed innovative approaches for lithium-ion battery recycling.
In two new papers, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have turned to the power of machine learning and artificial intelligence to dramatically accelerate battery discovery.
