As humanoid robots enter their first true mass-production year in 2025, the global robotics industry is accelerating at remarkable speed. With expanding market potential and increasingly diversified application scenarios, the capabilities demanded from humanoid robots continue to advance. According to the World Robot Conference and its “Top 10 Potential Application Scenarios for Humanoid Robots,” the field now spans industrial operations, power-generation support, home services, inspections, and more. Yet three persistent challenges continue to hinder widespread real-world deployment: insufficient endurance, weakened power delivery under heavy workloads, and limited safety performance in extreme environments.

To help overcome these bottlenecks, BAK has launched RoPower, a dedicated kinetic-energy battery solution engineered for humanoid robotics. Designed to align the triad of “performance–battery–scenario,” the RoPower product family aims to accelerate high-quality development across the robotics sector.

Purpose-Built Power That Expands Operational Boundaries

In rugged outdoor environments and high-intensity logistics tasks, robots rely heavily on instantaneous, high-output bursts of power. The RoPower18650-30D is engineered for these demanding conditions. With an all-tab structure, it achieves a 70% reduction in internal resistance, delivering below 5 mΩ, doubling discharge capability and lowering temperature rise by 30%. Energy release becomes both safer and more efficient. A 50 A maximum discharge current provides strong, immediate power to support climbing, jumping, stair-ascending, and other high-load actions without stalling. Its fast-charge capabilities—from 10% to 80% in just 9 minutes—deliver a 200% improvement in charging speed, combining “high power + rapid replenishment” to greatly elevate operational efficiency.

In long-endurance scenarios such as home-service robotics and daily inspection tasks, run-time becomes the critical metric. The RoPower21700-65E offers 928 Wh/L volumetric energy density and 315 Wh/kg gravimetric energy density, extending battery life by up to 30% and reducing the frequency of charging cycles. With internal resistance below 8 mΩ and support for 4C maximum discharge, it ensures high-efficiency energy output. Its operational temperature window of –30°C to 60°C enables reliable performance during cold-weather patrols, high-heat workshop duties, and other harsh environmental tasks. Having passed 12 rigorous safety tests, the battery ensures stable, reliable robot operation even in complex real-world conditions.

For robots working in extreme or highly complex environments, strong energy reserves and comprehensive safety protection are both essential. The RoPower4695-330B delivers on these needs with 280 Wh/kg energy density, a 2,000-cycle lifespan, and robust long-term operational reliability—earning it a reputation as a “marathon runner” in the battery world. Its 15-minute rapid recharge reduces downtime and relieves endurance anxiety for nonstop deployments. The all-tab structure enhances safety by minimizing heat rise during charge–discharge cycles, thanks to internal resistance below 0.8 mΩ, and includes multilayer protections such as zero thermal propagation, supporting safe operation under extreme loads and severe environmental conditions.

Across all RoPower models, BAK delivers strong temperature adaptability and stable power output in both extreme cold and heat. The company has also expanded its product portfolio with a comprehensive “power–capacity–safety” matrix, enabling fine-tuned customization for different humanoid robot workloads and application scenarios.

BAK’s Executive Vice President Liu Zhibo noted:
“Energy is the life indicator of a robot and the foundation of performance breakthroughs. Every additional 1 Wh/kg in energy density or every 0.1C improvement in charging capability opens the door to hundreds—if not countless—new application possibilities. Moving forward, BAK will continue to identify key pain points in the robotics sector and enrich our battery family. Our vision is for every cell to become a key that unlocks new potential—providing full-lifecycle energy support for the large-scale deployment of humanoid robots and driving limitless future exploration.”
