Researchers in India have combined two chemistries to boost the capacity retention of an anode material in lithium-ion batteries.
The team from the Indian Institute of Technology (IIT) Madras combined the lithium ion insertion reaction from lithium-ion batteries and the sulfur redox reaction from lithium-sulfur batteries to increase the battery’s overall capacity.
Two US lead-acid companies have teamed up in a joint technology assessment program to drive the comercialisation of their anode and material technology.
Large format bi-polar battery developer Advanced Battery Concepts, (ABC) and lead-carbon energy storage firm Axion Power International will assess the performance, efficacy and cost of the technology and materials in ABC's ‘GreenSeal’ bipolar battery.
A new consortium has announced it will buy a mill that will produce anode-ready spherical graphite (SPG) for lithium batteries in the US.
The group has announced it will buy a micronising and spheronising mill to produce the material, which is critical for lithium-ion battery anode materials.
German researchers have used apple leftovers as a carbon-based active anode material to create a sodium-ion battery with the performance of lithium-ion.
Researchers Professor Stefano Passerini and Dr. Daniel Buchholz of the Helmholtz Institute Ulm of Karlsruhe Institute of Technology claim apple waste has the right electrochemical properties for use in sodium-ion batteries.
Scientists from the University of Maryland have used an anode made of carbonised oak leaf to boost performance of a sodium battery.
Using the ‘leaf’ anode, scientists found a battery could hold 90% of its charge after 200 cycles and kept its charge efficiency at around 75%. The results were unveiled in a paper published in the journal ACS Applied Materials Interfaces.
Anode production for Alevo Energy’s utility-scale batteries has begun at its 3.5-million square-foot plant in Concord, US.
The North Carolina firm’s production line is housed in about a third of the plant’s 600,000-square-foot basement.
Once installed, the company’s cathode-production line will fill another third of the basement along with testing and other manufacturing equipment, including ovens.
The plant will manufacture the company’s Gridbank battery energy storage systems, which use Solith’s advanced lithium-ion battery formation.
A deadline for the first completed GridBank batteries to roll off the line has not yet been finalised.

Dexmet has introduced new microgrid anode and cathode foil materials down to 25 micron (.001”) in both aluminum and copper at widths up to 305mm (12”).
These thinner materials produce very small openings in the material, and should prove to be the perfect anode and cathode electrode solution for improved overall cell performance.
