==SULFIDE SOLID ELECTROLYTE MATERIAL, GAS-PHASE SYNTHESIS METHOD FOR MATERIALS THEREOF AND APPLICATION THEREOF - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240030485 titled 'SULFIDE SOLID ELECTROLYTE MATERIAL, GAS-PHASE SYNTHESIS METHOD FOR MATERIALS THEREOF AND APPLICATION THEREOF

==Simplified Explanation==

The abstract describes a gas-phase synthesis method for a sulfide solid electrolyte material, as well as its application. The method involves weighing a lithium (Li) source and a metal (M) source in a defined ratio, where the M source is an oxide or sulfide of certain elements from the third to sixth period of the periodic table. The raw materials are mixed and placed into a furnace. A sulfur (S) source is added to a sulfur source gas generation device, and a carrier gas is used to perform gas washing on the furnace at a set ventilation rate. The furnace is then heated to 200-800°C at a set heating rate, while introducing the gas containing the S source at the set ventilation rate. After a set duration, the furnace is cooled to room temperature and the sulfide solid electrolyte is removed.

* The gas-phase synthesis method involves weighing Li and M sources, mixing them, and placing them into a furnace.
* A sulfur source is added to generate a sulfur source gas, and gas washing is performed on the furnace using a carrier gas.
* The furnace is heated to a specific temperature range while introducing the gas containing the sulfur source.
* After a certain duration, the furnace is cooled and the sulfide solid electrolyte is obtained.

Potential applications of this technology:
* Solid-state batteries: The sulfide solid electrolyte material can be used as an electrolyte in solid-state batteries, which offer higher energy density, improved safety, and longer lifespan compared to traditional lithium-ion batteries.
* Fuel cells: The sulfide solid electrolyte material can be utilized as an electrolyte in solid oxide fuel cells, enabling efficient conversion of chemical energy into electrical energy.

Problems solved by this technology:
* Safety concerns: The use of sulfide solid electrolyte materials in batteries and fuel cells eliminates the risk of flammable liquid electrolytes, reducing the potential for accidents and fires.
* Performance limitations: Sulfide solid electrolytes have higher ionic conductivity than traditional oxide-based electrolytes, leading to improved battery and fuel cell performance.

Benefits of this technology:
* Enhanced battery performance: The use of sulfide solid electrolytes can result in higher energy density, faster charging rates, and longer cycle life in batteries.
* Improved fuel cell efficiency: Sulfide solid electrolytes enable lower operating temperatures and higher power densities in fuel cells, leading to improved overall efficiency.
