Inx Unveils Solid-State Battery Cells Amidst New Power Bank Standards

As new Chinese standards and mandatory CCC certifications reshape the power bank industry, the game is no longer just about capacity or wattage. Safety, energy density, and consistency of battery cells are now the true benchmarks for compliance and user trust.

At the 2026 World Power Bank Conference, Inx debuted its PB02 solid-state electrolyte battery cell. With 12% of market products flagged for safety issues in Q1 2026—80% of which were thermal runaway risks—battery safety has shifted from a feature to an absolute requirement for market entry.

New standards are formalizing this safety order. The PB02 cell, sized at 506578, delivers 18.2Wh and 5100mAh at just 58g. By pushing gravimetric energy density over 310Wh/kg and volumetric energy density over 685Wh/L, it allows for significantly thinner and lighter power banks without sacrificing performance.

Designed to meet GB 47372-2026, the PB02 excels in safety. It passed stringent nail penetration tests with no fire or explosion, maintaining peak temperatures between 34.9°C and 41.3°C and retaining stable voltage. Inx tackles common solid-state hurdles like high impedance and anode short-circuits using proprietary HICORE and TIE interface technologies, successfully balancing performance and safety.

Since 2020, Inx has focused on lithium-metal solid-state innovation across electronics, drones, and robotics. With the industry entry bar rising under GB 47372-2026, the PB02 cell marks a new focal point for brands looking to innovate, offering a clear path toward safer, lighter, and more powerful charging solutions.
