Semi-solid-state battery cells

Global shipments of semi-solid-state batteries are expected to exceed 15 GWh in 2026, with Chinese companies accounting for over 70% of the global market share. Among these, semi-solid-state batteries have achieved automotive-grade mass production first, while all-solid-state batteries have entered the prototype testing phase. China's solid-state battery industry has formed a pattern of parallel development along three technical routes: oxide, sulfide, and polymer. Oxide semi-solid-state batteries, due to their high stability, excellent low-temperature performance, and moderate mass production difficulty, have become the preferred route for commercialization in 2026.

Semi-solid-state batteries, which relevant authorities plan to uniformly name "solid-liquid batteries," are a type of battery that uses a hybrid solid-liquid electrolyte. They incorporate a solid electrolyte while retaining some liquid electrolyte, building upon the foundation of traditional lithium-ion batteries. Solid electrolytes contribute to improved battery safety and energy density.

Guoxuan High-Tech possesses ternary lithium battery technology, but safety concerns prevented its large-scale deployment. Now, through semi-solid-state and all-solid-state batteries, it has achieved a high-safety, high-energy-density product line, filling this gap.

From May 16th to 17th, Guoxuan High-Tech held its 2025 Global Technology Conference in Hefei. At the conference, Guoxuan High-Tech launched six new battery products, and executives including Zhu Xingbao introduced a series of advancements: the long-awaited all-solid-state battery has entered the pre-mass production stage; the G-Yuan quasi-solid-state battery with a range of 1000 kilometers, the G-Xing heavy-duty truck standard box capable of 12 years of continuous use, and the world's first single-compartment 20MWh energy storage system were also launched.

In terms of product portfolio, Guoxuan High-Tech covers a wide range of scenarios, including passenger cars, commercial vehicles, and energy storage; technologically, it extends from material innovation to intelligent manufacturing solutions.

Of course, the most attention-grabbing aspect is the progress in solid-state battery research and development.

Currently, Guoxuan High-Tech has already... In solid-state batteries. Public information shows that Guoxuan High-Tech adopts an aggressive dual-track strategy, currently offering two product lines: "G-Cut Battery" (semi-solid/solid-liquid hybrid battery) and "Jinshi Battery" (all-solid-state battery). The "G-Cut Battery" line retains approximately 5%-10% liquid electrolyte to improve ionic conductivity and address the current problem of high interfacial impedance in all-solid-state batteries. The "Jinshi Battery" line uses an oxide electrolyte technology route, completely eliminating liquid electrolyte, with a target of small-batch vehicle installation by 2027.

Guoxuan High-Tech publicly showcased its semi-solid-state battery product for the first time—580mm long, 120mm wide, 9mm thick, with a capacity of 136Ah, a weight of 1341 grams, and an energy density of 360Wh/kg. This battery can currently pass a 180℃ 30min hot box test, exceeding national standards.

Guoxuan High-Tech's first-generation semi-solid-state battery can pass a 1mm penetrating needle penetration test, while the second-generation product can pass a 5mm penetration test. Penetration test.
