EVTank predicts that the global solid-state battery market will see a compound annual growth rate (CAGR) of over 80% from 2024 to 2030. Given this growth rate and the share of consumer electronics applications, this specific market segment is poised for resonant expansion. For battery enterprises, accelerating industrial implementation and building mass production capabilities are becoming key to securing a stronger position in the consumer electronics supply chain.

In the crucial transitional phase towards all-solid-state batteries, Sunwoda has taken the lead in the consumer battery sector by delivering answers on both the 'technology' and 'mass production' fronts. Furthermore, at the 15th China International Battery Industry Expo (IBIE 2025) opening on October 10, Sunwoda publicly showcased its series of consumer semi-solid-state battery products for the first time and held a dedicated technology sharing session.

At the session, the company's technology expert, Dr. Cai Tingwei, provided an in-depth live interpretation, comprehensively displaying Sunwoda's technological innovations, mass production achievements, and future plans in the semi-solid-state battery field, making it a central focus of the exhibition.

Multi-Dimensional Breakthroughs Overcoming Traditional Battery Weaknesses

Dr. Cai Tingwei stated that Sunwoda possesses strong capabilities in its consumer battery business, capable of providing full 3C high-end lithium-ion battery solutions with significant advantages across multiple dimensions including energy density, charging speed, product performance, and form factor design. Its semi-solid-state technology, through coordinated innovation in materials, structure, and processes, systematically addresses typical pain points of traditional batteries, forming four core advantages:

Undeterred by Low Temperatures: Leveraging a solid-liquid synergistic mechanism, it maintains over 70% capacity and stable discharge performance even in extreme environments as cold as -30°C, overcoming the poor low-temperature performance of traditional lithium batteries.

Safety Assured: An internal high-strength protective network significantly enhances abuse tolerance, withstanding rigorous tests like crushing and impact, ensuring a 'safety net' for every power usage experience.

Broader Operating Temperature Range: Breaking the limitations of traditional lithium batteries being 'afraid of cold and heat,' it achieves stable operation across a wide temperature range of -30°C to 60°C, perfectly adapting to diverse usage scenarios like home, outdoor, and industrial auxiliary applications.

Simplified Process: Defying the notion that 'high technology equals high cost,' and paired with automated production lines (100% automation rate), it enables rapid transition from 'design finalization to mass production,' with a stable overall process yield rate exceeding 96%.

Full-Chain Systematic Support Enables Rapid Mass Production

The rapid realization of Sunwoda's semi-solid-state batteries stems from systematic capability support across the entire 'R&D - Pilot - Mass Production' chain. In September 2021, the company officially initiated the R&D project. After finalizing the core technology in March 2024, cumulative production surpassed 8 million units, fully demonstrating its leading technology conversion capability and large-scale manufacturing strength.

Regarding key technology breakthroughs, Sunwoda systematically studied the structure-property relationship between the composition/microstructure of solid electrolyte materials and their performance, and deeply explored the synergistic interaction mechanism between the solid and liquid phases. This identified the key performance optimization path for semi-solid-state batteries and the design scheme for interface regulation. Building on this, by optimizing the slurry preparation process, challenges like agglomeration and uniform dispersion of ultrafine powders were solved, achieving efficient, high-quality production of semi-solid-state batteries. To date, over 70 patents related to consumer semi-solid-state battery technology have been applied for.

Behind this mass production capability lies over a decade of technological accumulation and global layout by Sunwoda: Since 2011, the company has been developing consumer cell R&D in-house, focusing on the R&D and manufacturing of consumer polymer cells and small power cells. Its products cover smart terminals including smartphones, tablets, laptops, wearable devices, drones, power tools, smart mobility, and smart home products, engaging in deep cooperation with numerous renowned domestic and international enterprises.

Full-Category Compatibility, Continuously Leading Battery Industry Upgrades

Starting with mobile phone battery packs, Sunwoda has now grown into a global leader in lithium-ion batteries: Its mobile phone battery shipment volume has ranked first globally for five consecutive years (with a 34.3% market share), and it is also the world's second-largest laptop and tablet battery manufacturer. This profound industrial accumulation provides strong assurance for the rapid implementation of semi-solid-state technology.

Dr. Cai Tingwei pointed out that the mass production of the company's consumer semi-solid-state batteries holds significance far beyond the consumer industry itself; it provides a crucial 'commercial springboard' for the entire semi-solid/all-solid-state battery technology roadmap. In the future, Sunwoda will continue to iteratively upgrade its solid-state technology towards adapting to batteries with high energy density (≥1000 Wh/L), high capacity (≥10 Ah), and high voltage (≥4.60 V).

The company has successfully verified the mass production feasibility of semi-solid-state technology in the consumer battery field. Currently, these products are widely used in consumer electronic devices such as mobile phones, laptops, wearables, power banks, and drones.
