Custom Battery Materials Development

Cathodes, Anodes, & Solid Electrolytes

NEI Corporation specializes in producing non-commodity cathode, anode, and solid electrolyte battery materials. Our core competency is in providing compositions and powder morphologies that are not readily available in the market. We work closely with both lithium-ion battery developers and manufacturers to attain specialty battery materials that are ideally suited for their application. Our extensive materials science background and ability to custom tailor materials has resulted in improved battery performance for our customers and provides new capabilities for enabling next generation batteries. We also have manufacturing capabilities in place to produce your custom material in large quantities, and all work is done in a highly confidential manner (view & download our NDA).
