Allotrope Energy has developed a new class of supercapacitors featuring Lignavolt, a nano-porous carbon material derived from pulp industry byproducts. The devices demonstrate 14–15 Wh/kg energy density—twice that of typical supercapacitors—enabling higher energy recovery and power output in hybrid-electric vehicle systems. The company claims that the supercapacitors are well-suited to regenerative braking applications, allowing for… Read more…
