The key to the supercell is a noncombustible ceramic fiber material that each jelly roll sits in like an egg in a carton. The material helps to control temperature throughout the cell and isolate damage caused by an overheated jelly roll. A metal shunt wrapped around each jelly roll and a flame retardant layer of the supercell wall that relieves pressure in the case of a thermal event add to its safety advantages.

The enhanced safety allows Cadenza to package the jelly rolls tightly for greater energy density, and the supercell’s straightforward design, which leverages many parts that are currently manufactured at low costs and high volumes, keeps production costs down. Finally, each supercell module is designed to click together like LEGO blocks, making it possible for manufacturers to easily scale their battery sizes to fit customer needs.

Cadenza’s safety, cost, and performance features were validated during a grant program with the Advanced Research Projects Agency-Energy (ARPA-E), which gave the company nearly $4 million to test the architecture beginning in 2013.
