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

Israel-based 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.

The CEO of Australia-listed UltraCharge 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.
