Current research has sought to eliminate dependence on toxic lithium-ion batteries by creating a new battery system which enables a longer lifespan and carbon reduction capabilities. Metal-carbon dioxide batteries [MCBs] have posed a potential solution to these safety and environmental concerns.
However, MCBs exhibit prohibitively low power density at low temperatures, produce solid deposits which block functionality, and fail to capture or store carbon dioxide from the air. Because of these
limits to power density, as well as the use of precious metals, MCBs have been slow to be adopted.
Dr. Dong and his team have invented a new type of MCB which offers a disruptive enhancement of power density without the use of precious metals. This battery can operate in flow battery mode to decouple power and storage capacity that offers modularity and scalability. It also avoids solid blockage issues, is rechargeable, and produces a carbon negative effect.
