Core Insights - The article highlights the increasing importance of solid-state batteries as humanoid robots approach commercialization in 2026, with a projected demand for solid-state batteries exceeding 74 GWh by 2035, representing a growth of over 1,000 times from 2026 levels [2][5]. Group 1: Current Battery Technology - Currently, humanoid robots primarily use liquid lithium batteries, with most models having a battery capacity below 2 kWh and a runtime of 2 to 4 hours [6][8]. - High-nickel ternary lithium batteries (NMC/NCA) are the mainstream choice for robot batteries due to their relatively high energy density, while lithium iron phosphate batteries (LFP) are used for lower endurance applications [6]. Group 2: Future Developments - To achieve a runtime of 5 to 8 hours, strategies such as battery swapping technology are being explored, allowing for continuous operation without rebooting [7]. - The adoption of high energy density battery technology, such as solid-state batteries, is expected to significantly enhance the runtime of humanoid robots to over 4 hours [7]. Group 3: Challenges in Battery Development - The development of humanoid robot batteries faces two main challenges: the rapid iteration of core technologies affecting battery customization and the current focus on finding scalable commercial applications rather than improving battery life [8]. - Despite these challenges, the demand for high energy density, high discharge rate, and high safety batteries presents an opportunity for solid-state batteries to demonstrate their advantages [8].
