CustomCells Opens Battery Headquarters - Battery-News


In a quiet facility on Germany’s “Energy Coast,” engineers at CustomCells are crafting lithium-ion batteries unlike any others in Europe. This independent German company specializes in tailor-made high-performance battery cells, the kind that have powered Porsche’s electric hypercars and are now slated to energize cutting-edge electric aircraft. CustomCells’ cells boast exceptional energy density and resilience to extreme temperatures – qualities prized not only in luxury sports vehicles but also in military drones and autonomous submarines. As Europe strives to wean itself off foreign battery imports, CustomCells has emerged as a homegrown champion at the nexus of innovation and industrial production. Founded as a spin-off of a renowned German research institute, the company embodies Europe’s push for technological sovereignty in energy storage. Its story – from supplying a revolutionary air-taxi startup to weathering industry upheavals – offers a glimpse into how Europe’s strategic autonomy ambitions are being powered, one battery cell at a time.
