Hydrocarbon fuels have energy densities that are at least 100 times greater than that of current lithium-ion batteries. Even with projected improvements in battery technology as far out as 2045, batteries are still expected to be significantly less energy-dense than gasoline. However, the energy density of the actual storage medium may not be the best… Read more »

Layered oxide cathode could make sodium-ion batteries an attractive option for EVs
Researchers at the US Department of Energy (DOE)’s Argonne National Laboratory have invented and patented a new battery cathode material that replaces lithium ions with sodium and could be significantly cheaper. The research team has developed a layered oxide cathode for sodium-ion batteries. A layered sodium nickel-manganese-iron (NMF) oxide cathode efficiently inserts and extracts sodium,… Read more »
Researchers demonstrate a four-electron reaction that improves energy density in Li-air batteries
Lithium-air batteries could theoretically deliver an energy density comparable to that of gasoline. However, in most systems, the reaction pathways either involve one- or two-electron transfer, leading to lithium peroxide (Li2O2) or lithium superoxide (LiO2), respectively. Researchers at the Illinois Institute of Technology and Argonne National Laboratory are investigating a way to create a lithium-air… Read more »
Li-Bridge calls for building a domestic US battery supply chain
Public-private alliance Li-Bridge, representing the US battery ecosystem, has released an action plan to accelerate creation of a robust domestic manufacturing base and supply chain for lithium-based batteries. The alliance was convened by the DOE and is managed by Argonne National Laboratory. The report’s 26 recommendations include a buying consortium for raw energy materials, a… Read more »
SAE Power Rating can now be applied to EVs
SAE International has released a standard document, “J2908 Vehicle Power and Rated System Power Test for Electrified Powertrains,” that defines methods to determine peak power ratings for electrified vehicles, and establishes a framework for testing, data post-processing and reporting of SAE System power for vehicles with electrified powertrains. “SAE Certified Power was designed for conventional… Read more »
Researchers create room-temperature 1,000+ cycle solid-state Li-air battery
Researchers from the Illinois Institute of Technology, Argonne National Laboratory, and University of Illinois at Chicago say they have created a room-temperature solid-state lithium-air battery that is rechargeable for 1,000 cycles, has a minimal polarization gap, and operates at high rates. In “A room temperature rechargeable Li2O-based lithium-air battery enabled by a solid electrolyte,” published… Read more »
Researchers study particle boundaries in cathodes, develop new NMC cathode design
Image shows single crystals of cathode material: (A) no internal boundaries and (B) internal boundaries visible. (Image by Argonne National Laboratory.) A research team has developed a new NMC cathode design that prevents cracking in cathode particles through a structure that doesn’t have boundaries between particles. “A different approach to avoid this cracking involves single-crystal… Read more »
Researchers develop closed-loop method for lithium recovery from batteries
A team of researchers from Worcester Polytechnic Institute and the DOE’s Argonne National Laboratory have developed a closed-loop process for recovering lithium from lithium-ion batteries. In an article published in Green Chemistry, the researchers write: “We developed a sustainable lithium recovery process, which can selectively leach and recover lithium with formic acid before recycling valuable… Read more »
Rice researchers find misaligned crystallites in cathodes limit lithium flow
Researchers at Rice University have found that stress between misaligned crystallites in cathodes limits the flow of lithium. In an article published in ACS Energy Letters, the researchers write: “As an important battery cathode material, reaction distribution in lithium iron phosphate (LiFePO4) has been extensively studied in dispersed particle systems, but remains poorly understood for… Read more »
