Company Overview

Adden Energy is a technology company, spun out of Harvard University in 2021, that is developing next-generation solid-state batteries for electric vehicles (EVs). The company's core innovation is a lithium-metal battery that utilizes a 'dynamic stability' phenomenon to enable self-healing components, which prevents the formation of dendrites—a common cause of battery failure. This technology aims to deliver significantly improved performance over current lithium-ion batteries, including faster charging times (under 10 minutes), a longer lifespan (over 10,000 cycles), higher energy density, and enhanced safety due to non-flammable materials. Adden Energy's mission is to accelerate the mass adoption of EVs by making batteries that allow electric cars to surpass internal combustion engine vehicles in every key metric, including cost and convenience. The company has received venture funding and is scaling its technology from lab-scale prototypes to commercial production, having commissioned a pilot production line in early 2025 to supply sample cells to automakers and other industrial clients.
