US researchers open door for magnesium batteries to disrupt the ESS market

Thu, 12/03/2020 - 09:36 -- Paul Crompton

Researchers from the University of Houston and the Toyota Research Institute of North America (TRINA) have developed a new cathode and electrolyte that could help magnesium batteries compete with lithium-ion.

The teams have demonstrated a magnesium battery capable of operating at room temperature and delivering a power density comparable to that offered by lithium-ion batteries.

Engineering upgrades helps boost lithium-ion cathode recycling plant capacity by 150%

Thu, 06/11/2020 - 12:05 -- Paul Crompton

Metals firm American Manganese has more than doubled the capacity of its pilot lithium-ion battery cathode recycling plant in the US through engineering upgrades. 

The Canadian company raised capacity from 64 kg/day to 160 kg/day by adding thermal control of exothermic reactions that enable the plant to operate at higher pulp density.

Russian scientists develop alternative cathode material for metal-ion batteries

Fri, 04/24/2020 - 12:08 -- Paul Crompton

Scientists from Russia’s Skolkovo Institute of Science and Technology (Skoltech) have created a metal-ion cathode material based on titanium fluoride phosphate.

Researchers at Soltech’s Center for Energy Science and Technology (CEST) have reported their KTiPO4F cathode has exhibited a high electrochemical potential and “unprecedented” stability at high charge/discharge rates.

Scientists in China develop high-performance lithium-sulfur battery cathode

Wed, 04/22/2020 - 14:06 -- Paul Crompton

Scientists at the Dalian Institute of Chemical Physics (DICP) at the Chinese Academy of Sciences have developed a cathode they claim will increase the performance capabilities of lithium-sulfur batteries.

Teams led by professor Jian Liu (pictured) and professor Zhongshuai Wu have increased the catalytic activity and sulfur loading of lithium-sulfur batteries by using a mesoporous carbon nanoreactor decorated with Fe1-xS electrocatalyst nanoparticles (Fe1-xS-NC) as the cathode.

Posco shake-up bid to boost materials sales

Mon, 01/14/2019 - 00:00 -- John Shepherd

South Korea’s Posco is set to merge two of its business units to boost its global share of the battery materials market.

Posco’s board is expected to approve the merger of its Chemtech and ESM lithium-ion cathode materials divisions next month— on condition that no more than 20% of shareholders object.

If approved, the merger would take place in April 2019. Chemtech would integrate all group R&D capabilities for cathode materials to “fully develop next-generation cutting-edge products, while also promoting sales expansion”.

Cabot Corp, Saft in US low-cobalt cathode research

Mon, 10/22/2018 - 00:00 -- John Shepherd

The US Department of Energy (DOE) has selected speciality chemicals firm the Cabot Corporation as a technology partner to develop low-cobalt cathodes for next-generation lithium-ion batteries.

Cabot will work with researchers at the DOE’s Argonne National Laboratory and French battery maker Saft for the project. Argonne will assist in the synthesis of low-cobalt cathode compositions, while Saft will assist in the manufacture of batteries to validate performance of novel low-cobalt cathode formulations.

The DOE said it is investing a total of US$80 million “to explore more sustainable, affordable options” than cobalt— and “ultimately improve access to electric vehicle technology”.
