The Pure Lithium battery

Three step process

Start with brine that contains dissolved lithium salts.

The solid electrolyte* selectively extracts lithium from the brine and deposits lithium metal onto the copper substrate.

The laminate of the lithium metal negative electrode and the solid electrolyte is joined to the positive electrode.

The Pure Lithium technology, sourcing and process has eliminated the barriers to mass adoption of lithium metal batteries

Low cost feed stock

Earth abundant materials and the carbon intensity of their processes are considered as a precondition to scalability. Readily available, low-cost Li feed stock of varying quality ensures a secure supply chain, insulated from price fluctuations.

Clean process

Room temperature production process is clean, scalable and sustainable.

Vertically-integrated production

Technology enables vertical integration of Li metal production with the battery production process. Vertical integration is cost efficient, eliminating the high cost and handling issues for transporting and storing lithium metal.

One step process

Li is chemically bonded to a substrate creating a full anode in one production step. Lithium metal is never exposed to air, preserving the integrity of the material.

Manufactured in a charged state

Batteries manufactured in a charged state, reducing time and costly formation cycles. The Pure Lithium battery can be produced in one day. Compared to: Lithium ion requires 1.5-3 weeks for formation of the anode.

US based manufacturing, sourcing

Pure Lithium manufacturing process is possible within the United States, securing our energy supply chain, supporting energy independence, and creating domestic jobs.

Electrode purity

Pure lithium electrode is elementally pure, and does not contain impurities.

Why vertical integration?

Pure Lithium believes lithium metal batteries are not viable without vertical integration. A secure supply chain is critical and Pure Lithium is building it.

Vertical integration preserves the quality and integrity of lithium metal electrodes, overcoming multiple technical integration issues. This enables the finished product to be deployed on a mass scale. Vertical integration dramatically reduces costs with an integrated supply chain minimizing the transportation of feedstocks.

Pure Lithium is developing a full domestic feedstock sourcing, lithium metal electrode, battery production and distribution. This model can be scaled globally, so all localities can produce their own lithium metal batteries.
