UltraCharge raising AUD2.5m ‘to accelerate Li-ion tech’

Australia-headquartered lithium and flow battery developer UltraCharge has told BBB it is finalising a raise of AUD2.5 million ($1.9m) to boost battery tech investments.

UltraCharge CEO Kobi Ben-Shabat (pictured) said the cash would be used in part to expand development of titanium dioxide (TiO2) as an alternative to graphite in the anodes of lithium-ion batteries, in a bid to improve fast charging capabilities, lifespan and safety.

Paraclete cuts formation time down to size

Paraclete Energy, a Michigan based lithium ion materials supplier, made a strong push for the acceptance of prelithiated anode materials at the Battery Show Europe last week, with the launch of prelithiated SM-Silicon.

Prelithiated nanoparticle SM-Silicon/PL has a proprietary surface modifier that acts as a protective shell from air and moisture and has an artificial SEI for cycle stability. Not only will customers be able to incorporate Paraclete Energy’s cycle stable SM-Silicon™ into their anode to achieve the highest capacity possible for their batteries, but they will also be able to reap the benefits mentioned an aqueous compatible prelithiated anode in short reduced formation time, said the company.

Lithium and sulfur combined in new anode material

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.

US anode and material firms join forces to drive lead-carbon commercialisation

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.

Consortium buys SPG mill to produce anode-ready materials for Li-ion batteries

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.

Sodium-ion reaches lithium-ion performance with carbonised apple waste

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.

Baked leaf leads to better sodium 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.

Alevo start production of utility scale Li-ion ESSs

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.

Thin foils from Dexmet

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.
