Driven by the large-scale application of electric vehicles around the world, lithium-ion batteries have experienced rapid development in the past decade, creating a trillion-level industry. However, existing liquid lithium-ion batteries are approaching their energy density limits and pose certain safety risks. Therefore, driven by the demand for batteries with high energy density, high safety, and long life, all-solid-state batteries (ASSBs) are regarded as an innovative technology to accelerate the popularity of electric vehicles. Sulfide solid-state battery is a new type of high energy density battery with the advantages of high safety, high cycle life and high energy density.

Prospects:

● High energy density: Sulfide solid-state batteries have high energy density and can provide longer use time and higher power output.

● High safety: Sulfide solid-state batteries use solid electrolytes, which have high thermal stability and breakdown resistance, and can effectively improve battery safety.

● Long cycle life: Sulfide solid-state batteries have good cycle stability and anti-polarization properties, which can achieve longer cycle life and more stable battery performance.

Research direction:

● Material optimization: Preparing the coating of sulfide solid-state battery pole pieces through ultrasonic spraying technology, optimizing the composition and structure of the material to improve battery performance and stability.

● Interface engineering: Ultrasonic spraying technology is used to form an interface layer between the electrode and the electrolyte to improve the ion transmission rate and interface stability of the battery.

Application areas:

● Electric vehicles: Sulfide solid-state batteries have high energy density and high safety, and can be used as the power source for electric vehicles, providing longer cruising range and higher safety performance.

● Renewable energy storage: Sulfide solid-state batteries can be used to store renewable energy, such as solar and wind energy, to balance energy supply and demand and improve energy efficiency.

Advantages Advantages:

● Uniformity: Ultrasonic spraying technology achieves uniform distribution of coatings and provides better battery performance.

● Controllability: Precisely control the thickness of the coating to meet specific battery requirements.

● Save materials: Ultrasonic spraying technology can atomize materials into tiny particles, improve material utilization and reduce material waste.
