What is Group1 battery technology?

Group1 is a battery technology and engineered material company. Potassium-ion batteries (KIB) are the domestic, credible alternative to LFP-based Lithium-ion batteries (LIB). But they are bottlenecked chiefly by the lack of high-quality, engineered cathode active material.

What does Group1 do?

Group1 aims to practically enable high-power and long-cycling Potassium-ion batteries that can meet society’s future growth needs. Group1 is he world's 1st engineered materials company focused on Potassium-ion batteries. Continuing the lineage of innovation from Nobel laureate Prof. JB Goodenough.

What is Group1 technology?

Developed in the legendary lab of 2019 Chemistry Nobel laureate Professor JB Goodenough (co-inventor of the LiB), Group1's game-changing technology is the most practical beyond-lithium solution.

Will Group1's KPW cathode materials accelerate industry adoption?

“Industry adoption of Group1’s KPW cathode materials will be accelerated because of the materials’ fit with existing graphite anode materials, electrolytes, cell design, and manufacturing for lithium-ion batteries,” says the company.

What are Group1 KIBS?

Group1 also uses other abundant, domestically-available minerals. Group1 says its KIBs will deliver safety benefits over LIBs based on the use of safer electrolytes and oxygen-free materials. They’re also more efficient and faster-charging, as potassium ions in electrolytes have a smaller size and higher mobility compared to lithium ions.

What did Leigang do before he founded Group1?

Prior to co-founding Group1, Leigang served as the Principal Battery Scientist at Nanotech Energy, where he led cylindrical/pouch cell design, assembly, and test for the desired safety, voltage, capacity, resistance, cycling life, rate capability, etc. His work resulted in a product that made a $64M funding raise.
