Semi-Solid State Batteries: The Next Game-Changer in Power Bank Industry
Jan 20,2026
With the increasing frequency of mobile device usage and stringent 3C certification standards, electrical safety has further heightened public concern. The power bank industry is now embracing a technological revolution—semi-solid-state batteries. Compared to traditional liquid lithium-ion batteries, semi-solid-state batteries incorporate solid components into the electrolyte, significantly enhancing safety and energy density while balancing cost and mass-production feasibility. This technology is expected to address long-standing user concerns such as short battery life, slow charging, and safety risks, positioning itself as a key direction for next-generation portable energy storage.
The core advantages of semi-solid-state batteries include:
High Safety: Solid components reduce the risks of electrolyte leakage or combustion, making them suitable for extreme conditions such as high temperatures and impacts.
Increased Energy Density: Expected to improve by 20%–40% compared to traditional batteries, enabling longer usage with more compact designs.
Fast Charging Capability: Supports higher power input, significantly reducing charging time.
Long Cycle Life: Minimizes side reactions in the electrolyte, extending the overall battery lifespan.
Currently, numerous global technology companies are actively advancing semi-solid-state battery technology. Industry-acclaimed brands such as Marathon and ATL are leading the way. Hetai is collaborating closely with these pioneering enterprises to explore customized solutions for semi-solid-state batteries in the power bank sector, aiming to provide users with lighter, safer, and longer-lasting products.
The widespread adoption of semi-solid-state batteries will not only reshape the power bank market but also align with global demands for green energy and safe storage. Moving forward, Hetai’s OEM/ODM power banks will fully incorporate semi-solid-state batteries, driving the industry toward greater efficiency, reliability, and sustainability.
