#China to regulate #Lithium-ion battery industry amid fast expansion

Posted on June 19, 2024 by Nanthakumar Victor Emmanuel, P.Eng Leave a comment

China’s Ministry of Industry and Information Technology on Wednesday issued new guidelines for its lithium-ion battery industry, aiming to transform, upgrade and promote high-quality development amid rapid expansion in the sector.

The guidelines, following a proposal in May, will help firms scale back manufacturing projects that only expand production capacity, while enhancing technology innovation and product quality and trimming output costs, the ministry said.

Projects built on farmland and ecological zones would be required to be shut down, or strictly reined in and gradually removed.

Rapid expansion of production capacity along the lithium battery supply chain has led to a plunge in prices for products, including battery and raw materials, eroding companies’ profits in the world’s biggest market.

Industry planning and launch of new projects should be in line with national development of resources, ecological protection and energy saving management, the ministry said.

Safe and efficient energy storage is important for American prosperity and security. With the adoption of both renewable energy sources and electric vehicles on the rise around the world, it is no surprise that research into a new generation of batteries is a major focus. Researchers have been developing batteries with higher energy storage density and, thus, longer driving range. Other goals include shorter charging times, greater tolerance to low temperatures and safer operation.

One of the more promising such batteries has a lithium-containing cathode supplemented with nickel, manganese and cobalt (NMC). At the U.S. Department of Energy’s (DOE) Argonne National Laboratory, a team of scientists has recently developed a new coating method for NMC cathodes with high nickel content, which boosts the energy density substantially. The cathode is the positively charged battery component that supplies lithium ions that shuffle between it and the battery’s negatively charged electrode, called the anode, during cycling.

The repeated charging of batteries under conditions of high voltage and rapid recharge leads to structural instability and breakdown over time. To overcome the problem, Argonne scientists developed a new coating that allows the cathode particles to withstand the fracturing in their crystalline structure that had previously occurred upon cycling. They call this material “epitaxial entropy-assisted coating,” or EEC for short. According to Xu, “entropy assistance” ensures that the coating helps to prevent the breakdown of the material beneath it due to a thermodynamic effect, which leads materials to naturally become destabilized over time.

#India reaches out to critical mineral producers for processing technology

NEW DELHI: India has reached out to key critical mineral producers to bring in processing technology into the country, officials said. The move comes close on the back of the government rolling out auctions of critical mineral mines.

“Talks are on with the United States (US), Australia, and United Kingdom (UK), South Korea, and Japan for processing technology. Brazil and Argentina are also positive about collaborating with India,” a senior mines ministry official told ET.
According to another official aware of the plan, agreements with countries are being lined up and will soon be signed.

While India is going ahead with auction of mines holding critical minerals, there are no facilities for their beneficiation.

“We want to target India’s first critical mineral beneficiation and processing plant in the next 3-5 years,” the official quoted above said. “We want to ensure that development of critical mineral processing and extraction happen in parallel.”

#Pentagon plans #AI-based program to estimate prices for critical minerals

The US Department of Defense plans to develop a program to estimate prices and predict supplies of nickel, cobalt and other critical minerals, a move aimed at boosting market transparency but one that throws a new, uncertain variable into global metals markets.

The program, which received little attention after it was announced on a Pentagon website in October, is part of Washington’s broader efforts to jumpstart US production of critical minerals used in weapons manufacturing and the energy transition.

US output lags market leader China partly because attempts to build new American mines can be heavily influenced by commodity price swings.

The Pentagon’s work is being run by its Defense Advanced Research Projects Agency (DARPA) division, which was formed in response to the Soviet Union’s 1957 launch of the Sputnik 1 satellite and helped develop the Internet and the mRNA vaccine for Covid-19.

DARPA and the US Geological Survey plan to hire one or more private contractors to develop an artificial intelligence-backed model that would construct a metal’s “structural price” based on where and when it is produced, as well as labor, supply and other costs, according to documents seen by Reuters that describe the program, including a slide deck that DARPA presented last November to prospective contractors.
