BYD builds on its closed loop dream with second-life lithium-ion battery partnership

Tue, 01/05/2021 - 14:34 -- Paul Crompton

Chinese battery OEM and electric vehicle maker BYD will transform old batteries into energy storage systems through a partnership with Chinese lithium-ion recycling start-up Pandpower and Japanese trading house Itochu.

Old battery packs from buses, taxis and other vehicles manufactured by BYD will be collected from dealerships across China and turned into ship-container-sized power units for renewable energy and factories.

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.

World’s first test bench using CT surveillance on lithium-ion batteries is opened in Europe

Tue, 11/24/2020 - 17:15 -- Paul Crompton

Climatic chamber maker Weiss Technik has developed a test bench for lithium-ion batteries that aims to improve the safety, durability and performance of batteries as well as inform the development of EU-standards.

Developed at its German headquarters, the testing facility at the EU’s Joint Research Centre (JRC) in Petten, the Netherlands, will enable researchers to use computer tomography (CT) images during battery operation.

Lithium-ion battery fires spark global recall of 68,000 EVs amid over charging concerns

Tue, 11/17/2020 - 09:38 -- Paul Crompton

The root cause of fires that pushed General Motors to recall 68,667 Chevrolet Bolt electric vehicles is unknown but “could be” related to overcharging the high voltage lithium-ion batteries produced in South Korea by LG Chem. 

Concerns the batteries could catch fire when fully charged has led the US federal vehicle safety agency National Highway Traffic Safety Administration (NHTSA) to recommend charging up to 90% capacity until a software update is completed.

Greenpeace highlights need to repurpose lithium-ion as EV markets surge

Fri, 11/06/2020 - 10:06 -- Paul Crompton

Repurposing lithium-ion batteries from electric vehicles (EVs) into energy storage systems can help meet the world’s power needs as early as 2030, research by Greenpeace East Asia shows.

The organisation is calling for manufacturers to track the sale and re-collection of all their batteries, and introduce life cycle as a core performance metric for product design, emphasising standardisation and recyclability.

Scientists use algorithm to identify potential solid electrolyte materials for lithium-ion batteries

Mon, 11/02/2020 - 12:49 -- Paul Crompton

Theoretical scientists at Stanford University have identified a new class of materials that could lead to the development of more efficient solid-state lithium-ion batteries.

The materials—lithium, boron and sulfur— were identified after the team used a computer algorithm to screen more than 12,000 lithium-containing compounds in a materials database.
