Lithium has the atomic number 3 on the table of elements.
The chemical formulas for the lithium hydroxide and lithium carbonate used by battery manufacturers are:
Lithium hydroxide: LiOH, H2O
Lithium carbonate: Li2CO3

Lithium is a very light alkali element that is a critical component in the manufacture of batteries for the automotive industry. It is an essential and strategic raw material for meeting the challenge of the energy transition. Imerys has launched plans to start lithium mining and refining in central France.

Lithium: A highly strategic raw material
Pure lithium is a soft alkali element, which is white or silver in color. It is the lightest solid element on the planet, and floats on water. Being highly reactive, lithium is not found in its native state in the natural environment, but only in the form of ionic compounds.
Lithium is found in nature in aqueous salt solutions (brine) in salt flats (large, partially evaporated salt lakes) or – as at our Kaolin site in Beauvoir, France – in clay and hard rock such as granite and pegmatite.
Lithium is widely abundant, but there are only a few places on earth where it exists in adequate concentrations to make lithium mining economically viable. The biggest resources currently being mined are in Chile, Australia and China. There are only a few ongoing lithium mining projects in Europe, and most are still in the initial stages.
Lithium’s physical properties make it an essential raw material in the highly strategic market for lithium-ion batteries.
Main physical properties
- Very light
- High electrochemical potential
Lithium-ion batteries prized for their performance
The major application for lithium – and the one that has witnessed by far the fastest growth – is for energy storage in the form of lithium-ion batteries. Developed in the 1990s, lithium-ion batteries have become especially widespread in recent years. Compared to other types of batteries, lithium-ion batteries charge faster, last longer and have a higher energy density; as a result, they are lighter-weight batteries with a longer life.
Over the past few years, lithium-ion batteries have been adopted in a wide range of industries and notably the electric vehicle industry, which is growing rapidly. Given the climate challenges connected with the energy transition, that growth is likely to continue in the coming years: according to some estimates, the industry will expand fourfold between 2024 and 2035.
The EMILI project in Beauvoir
Imerys has launched the EMILI project to mine lithium at its Beauvoir site in central France.
Imerys’ lithium initiative is designed to address the dual challenge of the energy transition and economic sovereignty. It will aid in the creation of an integrated European supply chain for electric vehicle batteries by offering a local solution for one of the most strategic raw materials.
The EMILI project is one of the biggest lithium extraction projects in Europe to date. The site is expected to start production in the beginning of the next decade.
Imerys British Lithium project in the UK
Based in mid-Cornwall, the Imerys British Lithium project planned to produce over 21,000 tonnes of lithium carbonate every year, for over 20 years. Our lithium resource is located in an old china clay pit which has not been mined for a number of years.
Imerys announced early 2026 a strategic decision to place its Imerys British Lithium project into a care and maintenance phase, suspending active development for the foreseeable future. This decision is driven by capital allocation constraints, and the need to find a long-term partner to support the project.

In a major boost to Europe’s ambitions to decarbonize mobility, Imerys’ EMILI project has been awarded a €116 million grant from the European Union’s Innovation Fund.
April 23, 2026
On 22 April 2026, French President Emmanuel Macron visited Imerys' Beauvoir kaolin site in Échassières (Allier), dedicated to the EMILI lithium project. The visit was part of a broader government initiative to accelerate France's strategic industrial projects, notably marked by a cabinet meeting held in Montluçon.
January 29, 2024
Imerys has just announced the selection of two key sites in the Allier region in France for its lithium extraction and transformation project, EMILI. This move is part of an ambitious initiative to strengthen the European battery industry for electric vehicles and contribute to the energy transition.
June 26, 2023
A campaign of laboratory tests has made it possible to produce battery-grade lithium hydroxide using granite from the Beauvoir quarry. These encouraging results confirm Imerys’ technological capabilities and the effectiveness of the processes put in place for the EMILI project.
