Explore the EVE Energy 50E lithium-ion cylindrical 21700 battery cell including capacity, mass, energy density and performance data. Compare specifications and simulate battery behaviour using validated models in the Voltt.
257Wh/kg
771W/kg
Simulate and save up to 90% on cell evaluation time and cost
Run validated simulations on this cell - no test hardware, no waiting on the lab.
Top-level spec data shown here is directly from the manufacturer. Modelled and experimental metrics - including energy density, power density, TEL and discharge curves - are available through our simulation tools.
With Simulate you can configure packs, run custom dynamic power profiles, amend starting conditions and explore thousands of possible design configurations across our whole cell model database.

EVE Energy is a Chinese battery manufacturer headquartered in Huizhou, Guangdong, and one of the largest global suppliers by volume. It produces cylindrical, prismatic and pouch cells across LFP and nickel-rich NMC chemistries, including 21700 cells such as the 40P and 50E, plus primary lithium and sodium-ion cells. Its breadth is unusual: it is a top energy storage cell supplier while also producing 46-series large cylindrical cells for automotive customers such as BMW.
