Chinese battery giant CATL aims to enter US market

Contemporary Amperex Technology Limited (CATL) is hardly a household name to US EV advocates, but that could change if the company’s plans come to fruition. CATL, which was profiled last week by Bloomberg, was founded in 2011 and now sells more cells to EV-makers in China than any other firm. CATL hopes to raise $2… Read more »

Ionic Materials raises $65 million to develop its solid-state electrolyte

Ionic Materials has secured $65 million in a Series C financing round from investors in the battery manufacturing, consumer electronic and EV fields, who will be working with the company to speed the development of its solid polymer electrolyte battery material. “This funding round will allow us to add to our talented technical staff while… Read more »

Cummins acquires Johnson Matthey’s automotive battery business

Engine builder Cummins has acquired Johnson Matthey’s UK automotive battery systems business, a subsidiary that specializes in high-voltage battery systems for electric and hybrid vehicles. Cummins and Johnson Matthey also agreed to collaborate on the development of battery materials for commercial heavy-duty applications. Last October, Cummins acquired Brammo, which is known for designing and developing… Read more »

Adding graphene girders to silicon electrodes could double battery life

Graphite has long been the default choice of material for anodes, but researchers dream of replacing graphite with silicon, which has ten times the gravimetric energy density. Unfortunately, silicon has several issues that limit its commercial use – it expands during lithiation, causing particles to agglomerate in ways that impede efficiency, and it is not… Read more »

New EV battery recycling model quantifies cost and energy savings

What’s going to happen to all those lithium-ion batteries after they die? What’s the best way to recycle them? A new model developed at the DOE’s Argonne National Laboratory allows industry insiders to assess the money and energy savings from recycling EV batteries. ReCell, a closed-loop battery recycling model, offers preliminary estimates of total costs… Read more »

Scania and Northvolt partner to develop batteries for heavy vehicles

Scania, a member of the Volkswagen Group, and Northvolt, a 2016 startup that is building what it calls a European gigafactory for Li-ion batteries (with a planned 32 GWh annual capacity), have agreed to work together to develop and commercialize battery cell technology for heavy commercial vehicles. Scania will invest €10 million ($12.5 million) in… Read more »

UK motor manufacturer YASA secures £15 million in funding, opens new factory

Motor manufacturer YASA, which was spun out from the University of Oxford in 2009, has raised £15 million in a new round of funding, bringing the total raised by the company to £35 million. The company also announced the signing of long-term development and supply agreements with several automotive customers, and the opening of a… Read more »

Recycling worn cathodes to make new batteries

As lithium-ion batteries proliferate, the question of what to do with them when they wear out is becoming a major environmental concern. Less than five percent of used batteries are recycled today. Nanoengineers at the University of California San Diego have developed an energy-efficient recycling process that restores used cathodes from spent batteries and makes… Read more »

Aqueous anode enables super-fast charging

An international team of scientists, including researchers from the DOE’s Argonne National Laboratory, has discovered an anode material that enables super-fast charging and offers stable operation over many thousands of cycles. In a recent article in Nature Communications, Argonne Battery Scientist Jun Lu and colleagues describe a water-bearing compound, lithium titanate hydrate, that could replace… Read more »
