About Battery Resourcers

Enabling a circular economy.

Battery Resourcers is committed to changing the dynamics for processing end of life lithium ion batteries.

Battery Resourcers was founded in 2015 from technology created by Professor Yan Wang and his team at Worcester Polytechnic Institute. Battery Resourcers is committed to changing the dynamics for processing end of life lithium ion batteries.


Most lithium ion batteries are landfilled. If they are recycled, only the metal value from the batteries is recovered. Battery Resourcers proprietary process directly synthesizes new cathode materials from spent lithium ion cells.

Battery Resourcers manufactures and delivers low-cost cathode materials to the lithium ion battery market, enabling green technologies and resulting in less landfilled material.

We are creating a sustainable pathway forward.
