What Is Semi-Solid-State Battery Technology?
Semi-solid-state batteries replace the liquid electrolyte in traditional Li-polymer cells with a gel or semi-solid electrolyte. Often called "solid state power bank" technology in the consumer market, this next-generation chemistry fundamentally changes three things: energy density, thermal stability, and form factor.
"The solid-state battery market — including semi-solid-state — is projected to reach $963 million by 2030, growing at a 41.5% CAGR from $85 million in 2023. Within consumer electronics, solid-state micro batteries are forecast to grow from $1.67 billion to $3.87 billion at 14.88% CAGR. Semi-solid-state represents the first mass-production-ready step in this trajectory: delivering 50% thinner profiles, 30% higher energy density, and near-zero fire risk at only 20-40% cost premium over Li-polymer. Unlike full solid-state batteries which remain in lab/pilot phase until 2027+, semi-solid-state is shipping at scale today — and CES 2026 marked its consumer market breakout."

Semi-Solid-State vs. Li-Polymer vs. Solid-State
Not all "solid state power bank" claims are equal. True semi-solid-state batteries use a gel electrolyte with only 2.5-10% liquid content — a production-ready middle ground between traditional lithium-polymer and full solid-state technology that won't reach mass production until 2027+.

Brands Powered by Semi-Solid-State Technology (2026)
The semi-solid-state power bank market is exploding in 2026, with DTC brands, Japanese electronics giants, and crowdfunding projects all adopting this technology. Behind many of these brands is an OEM factory with semi-solid-state cell expertise.
Singapore — 5000-10000mAh, "Best of CES 2026" by TechRadar. 2.5% liquid content cells.
Kuxiu
Australia — S2/S3 MagSafe semi-solid power banks. Featured on The Verge.
Japan — 10000mAh with 2,000-cycle lifespan. Japanese retail market leader.
Neopow
US — X25 285W/25000mAh flagship. Crowdfunding record-breaker.
Meenova SolidPower
US — Kickstarter launch May 2026. Safety-first positioning.
Momax / Bull
HK / China — Premium consumer electronics retailers adopting semi-solid-state.
These DTC brands demonstrate the market demand — but most buyers need an OEM partner to bring their own semi-solid-state power bank to market. WOWOHCOOL provides the same production-grade semi-solid-state cells, with full OEM/ODM customization, MOQ from 500 units.
View Our 6 Semi-Solid-State Models →Why Semi-Solid-State Is Inherently Safer
Beyond certifications — the chemistry itself reduces risk. Semi-solid-state batteries contain dramatically less flammable liquid electrolyte than traditional Li-polymer, giving your brand a built-in safety story for retailers and end customers.
Reduced Thermal Runaway
Only 2.5–10% liquid electrolyte vs. 60–90% in standard Li-polymer cells. Less flammable material = dramatically lower fire propagation risk even under physical damage. The gel-state electrolyte solidifies above 60°C, self-containing thermal events.
UN38.3 + IATA Airline Ready
All models tested and certified for air and sea transport under UN38.3. Under 100Wh — permitted in carry-on per IATA Dangerous Goods Regulations. Full MSDS documentation included with every bulk shipment for customs clearance worldwide.
EU Battery Regulation 2023/1542
The new EU regulatory framework penalizes high-fire-risk chemistries. Semi-solid-state's reduced liquid electrolyte content positions your products ahead of the compliance curve — lower compliance burden, faster market access, stronger retailer confidence across the EU.
Global Market Certification Support
Need UL 2056 for North America, PSE for Japan, or KC for Korea? We coordinate the full application, testing, and documentation process. Typical turnaround: 4–8 weeks. Available for orders of 2,000+ units.
2,000+ Cycle Life = Less E-Waste
Semi-solid-state cells deliver 3–4× longer service life than standard Li-polymer (300–500 cycles). This directly reduces warranty claims and positions your brand favorably under EU right-to-repair and sustainability regulations coming into force 2026–2028.

Semi-Solid-State FAQ
What is a semi-solid-state battery power bank?▼
A semi-solid-state power bank uses gel-state or semi-solid electrolyte instead of liquid electrolyte found in traditional Li-polymer batteries. This delivers 50% thinner profiles, 30% higher energy density, lower fire risk, and longer cycle life (1,000-2,000 cycles vs 300-500 for Li-polymer). Often marketed as a "solid state power bank," true semi-solid-state technology contains only 2.5-10% liquid content.
What is the MOQ for semi-solid-state power bank OEM?▼
MOQ starts at 500 units for standard ODM models with custom logo printing. Custom OEM with tooling: 1,000-2,000 units. Sample turnaround: 3-7 days for standard, 10-15 days for custom.
Are semi-solid-state power banks safe for air shipping?▼
Yes. All WOWOHCOOL semi-solid-state power banks are UN38.3 certified and meet IATA air transport regulations. Capacity up to 27,000mAh (100Wh) is allowed in carry-on luggage per IATA passenger rules.
How is semi-solid-state different from full solid-state battery?▼
Semi-solid-state uses a hybrid electrolyte (partial liquid + partial solid) and is in mass production now. Full solid-state batteries are still in pilot production by manufacturers like Sunwoda and Svolt and not commercially available for power banks until 2027+.
Are semi-solid-state power banks safer than lithium-ion?▼
Yes. The gel electrolyte significantly reduces thermal runaway risk compared to traditional lithium-ion or Li-polymer cells. With only 2.5-10% liquid content (vs 60-90% in Li-polymer), there is dramatically less flammable material if the cell is damaged. This aligns with the EU Battery Regulation 2023/1542 which favors low-fire-risk chemistry.
How long does a semi-solid-state power bank last?▼
WOWOHCOOL semi-solid-state power banks deliver 1,000-2,000 charge cycles before reaching 80% capacity — that's 3-4x longer than traditional Li-polymer (300-500 cycles). At one full charge per day, this translates to 3-5+ years of daily use before noticeable capacity loss.
Which brands use semi-solid-state battery technology?▼
Notable brands launching semi-solid-state power banks in 2025-2026 include BMX SolidSafe (US, CES 2026 winner), Kuxiu (Australia), ELECOM (Japan, 2000-cycle), Neopow (US, 285W flagship), Meenova (Kickstarter), Momax (Hong Kong), and Bull (China). Many DTC brands source semi-solid-state cells through OEM factories — WOWOHCOOL offers the same technology with full customization from MOQ 500.
Can semi-solid-state power banks be taken on planes?▼
Yes. All WOWOHCOOL semi-solid-state power banks are under 100Wh and UN38.3 certified — fully compliant with IATA Dangerous Goods Regulations for carry-on luggage. No airline pre-approval is needed. Complete MSDS documentation is provided for international shipping and customs clearance.
