Joysun humanoid robot batteries utilize lithium metal anode technology (theoretical capacity 3860mAh/g, 10 times that of graphite anodes) paired with high-nickel ternary cathodes, achieving energy density over 400Wh/kg. This ultra-high energy density allows humanoid robots to carry lighter batteries while maintaining long operation hours. These humanoid robot batteries employ solid electrolyte systems, completely eliminating the flammability and explosion risks of liquid electrolytes, with thermal runaway temperature raised above 200°C. Joysun’s advanced battery technology helps humanoid robots integrate more flexibly and durably into human living and working environments.
