(Press-News.org) In a study publishing June 12 in the Cell Press journal Cell Reports Sustainability, researchers conducted the most comprehensive analysis to date on lithium supply and demand in China, Europe, and the USA. Despite that domestic lithium production in some of these regions could grow as much as 10 times by 2030, it would still fall short of the soaring demand for electric vehicles (EVs) without expanding imports or technological innovation.
“Lithium today is as important as gasoline in the industrial revolution,” says author Qifan Xia of East China Normal University in Shanghai. “While lithium reserves are substantial around the world, they are distributed unevenly across different countries. So, we were interested if the major EV markets can be self-sufficient.”
Together, China, Europe and the USA account for 80% of the world’s EV sales, and their demand is expected to increase further. The team estimated that China might need up to 1.3 million metric tons of lithium carbonate equivalent—a standard measure of lithium content—to produce new EVs. Europe might require 792,000 metric tons, followed by 692,000 metric tons for the US.
Based on existing and proposed lithium-mining projects from all three regions, the team found that China could produce somewhere between 804,000 and 1.1 million metric tons of lithium carbonate equivalent by 2030. Production in Europe could reach 325,000 metric tons, and in the USA, production could range from 229,000 to 610,000 metric tons in the next 5 years.
The results showed that even when these regions follow the most ambitious development plans to expand domestic lithium mining, none could fully meet their lithium needs through local production alone.
The USA and China could come close to meeting their needs if all proposed mining projects begin quickly. Europe would face the largest gap, and the team’s computer model showed that these countries would rely heavily on imports.
Currently, many of the lithium imports come from only a handful of suppliers, including Chile and Australia. The team, including co-author André Månberger at Lund University in Sweden, warned that increased imports by one region would directly reduce access for others, exacerbating supply constraints and straining international trade relations. For example, if China’s imports increase by 77%, imports to the US would drop by 84% and Europe's by 78%.
In addition to ramping up mining efforts, the study points to other means of easing future shortages. For example, adopting battery technologies that use less or no lithium—including sodium-ion batteries—could alleviate lithium shortages while supporting climate goals. Countries could also avoid the looming crisis by shifting the focus from producing personal EVs to promoting the use of public transit.
“Our study showed that without immediate action to expand mining, diversify suppliers, and rethink how we manage demand, the world risks delays in meeting critical climate and energy goals,” Xia says.

Your breath is one of a kind. A study published June 12 in the Cell Press journal Current Biology demonstrated that scientists can identify individuals based solely on their breathing patterns with 96.8% accuracy. These nasal respiratory “fingerprints” also offer insights into physical and mental health.
The research stemmed from the lab’s interest in olfaction, or the sense of smell. In mammals, the brain processes odor information during inhalation. This link between the brain and breathing led researchers to wonder: since every brain is unique, wouldn’t ...
The population across developed countries is getting older and the associated frailty and debilitation are becoming major health problems. This gradual muscle loss is accelerated by the poor capacity to repair damage and injury, especially after falls or surgeries.
Low muscle mass in the elderly — known as sarcopenia — leads to increased frailty and movement problems. Patients with sarcopenia are more likely to be hospitalized and develop other comorbidities, largely due to falls and fractures that tend to create health declines that quickly spiral out of control.
“We knew that a major contributor is the muscle stem cells that are needed to repair ...
All of us produce a growth factor – called IL-15 – which effectively protects us from cancers. It’s role is to boost the production of immune cells that can rapidly detect and kill cancer cells when they first appear. One of these cell-types is appropriately called Natural Killer Cells.
The problem is that cancer cells evolve numerous strategies to suppress immune cells like NK cells, even when these cancer cell are producing the immune boosting factor IL-15, and too often the cancer cells win. ...
Gland, Switzerland (IUCN) –Experts from the International Union for Conservation of Nature (IUCN) have analysed how targeted management of invasive alien species (IAS) can reduce extinction risks for threatened species across the European Union (EU), in line with the EU Biodiversity Strategy for 2030.
Published in the open-access journal NeoBiota, and funded by the European Commission, a new study identifies where and how targeted action against IAS (species that have been introduced to areas outside their ...
About The Study: In this cross-sectional study, U.S. drug overdose death rates entered a new wave of sustained deceleration in 2023 after 2 decades of increase. This shift may reflect changes in drug markets, treatment access, harm reduction efforts, and population-level risk. Although the decline is encouraging, persistent disparities highlight the need for targeted interventions and improved understanding of the underlying drivers.

About The Study: This study found that initiating fecal immunochemical test screening at age 40 to 49 was associated with further reduction in colorectal cancer (CRC) mortality and incidence compared with starting screening at age 50. These results provide strong empirical support for lowering the CRC screening age, with substantial public health implications.

(BOSTON) — About 30% of all respiratory tract infections are caused by coronaviruses, leading to widespread illnesses and, in some cases, to epidemic and even pandemic outbreaks, as we experienced with the COVID-19 pandemic. Despite the development of groundbreaking technology that enables the design of prophylactic vaccines, access to those vaccines is not equal across the globe, especially in low-resource countries, and also other hesitations prevent their adoption.
In addition, coronavirus variants are emerging ...
Out-of-body experiences – where people feel like spirits disconnected from their physical form – may be a coping mechanism triggered by trauma or other overwhelming stress, new University of Virginia School of Medicine research suggests.
That idea challenges the common assumption that out-of-body experiences, or OBEs, are solely a symptom of mental illness. Based on data from more than 500 people, the researchers, including UVA Health’s Marina Weiler, PhD, instead argue for a more nuanced perspective: that OBEs may represent an underlying issue that could be a better treatment target than the out-of-body experiences ...
WASHINGTON — In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six countries. Spanning thousands of kilometers, the experiment represents a significant step toward redefining the second and ultimately establishing a global optical time scale.
“The accurate time and frequency signals provided by atomic clocks are essential for many everyday technologies — like GPS, managing power grids and keeping financial transactions in sync,” said Helen Margolis, head of time and frequency ...
A third of the world’s population struggles with water scarcity. In many of these areas, fog holds water that could provide a lifeline — if only it could be captured.
Harvesting that water more efficiently has become the work of researchers from two colleges at Virginia Tech, who recently improved on their original fog harp design with a model that more closely resembles another musical instrument: a guitar. Their latest findings have been published by the Royal Society of Chemistry.
Harvesting water from resources such as fog is not a new idea. Archaeologists have found evidence of ancient ...
