Scientists from the Institute of Physics of the Czech Academy of Sciences have taken a step closer to simplifying battery production while improving stability and extending lifespan. They have introduced a new semi-solid substance for batteries that could transform the future of energy storage. The suspension electrolyte with salt particles enhances the performance and durability of dual-ion batteries.

In simple terms, a battery consists of a galvanic cell (a source of electric voltage) and an electrolyte—a liquid or solid solution that conducts electric current.

Unlike traditional electrolytes, which completely dissolve in the solution, the innovative electrolyte developed by the Czech physics team contains so-called suspended salt particles. These never fully dissolve but remain near the electrode surface, naturally creating a highly concentrated layer of anions that maintains the battery’s chemical balance during charging and discharging. This reduces undesirable side effects and results in longer-lasting, better-performing batteries.

“The new electrolyte technology is extremely promising for the battery industry. It can be integrated into dual-ion battery systems that use cheaper and more readily available materials. Our discovery brings dual-ion batteries closer to practical, real-world applications,” said Jiří Červenka, head of the Nanomaterials and Systems Group at the Institute of Physics of the Czech Academy of Sciences.

Stability, Fluidity, Easy Handling

Unlike standard single-ion lithium-ion batteries, dual-ion batteries store energy using two different ions from the electrolyte. This enables higher voltage and energy density.

To address one of the main limitations of dual-ion batteries—rapid depletion of active ions at the electrode interface—the researchers developed what they call a Suspension Electrolyte with Salt Particles (SPSE).

Thanks to its air stability, fluidity, and ease of handling even after long-term storage, the electrolyte is considered suitable for manufacturing and wide-scale applications.

Laboratory tests confirmed its stable performance and compatibility with commonly used battery materials such as zinc and graphite, according to the research team.

These properties indicate strong potential for affordable battery systems applicable in electric vehicles, renewable energy storage, and personal electronics.

The Czech scientists published their findings in the scientific journal Journal of Materials Chemistry A.
