Lithium-intercalating electrode material

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a lithium-intercalating electrode material for rechargeable lithium-ion batteries consisting of core-shell particles. The core is made of a transition metal oxide (preferably molybdenum trioxide), and the shell is a sulphide of the same transition metal (preferably molybdenum disulphide). This unique core-shell structure combines the desirable properties of both oxides and sulphides, offering improved stability, capacity, and cycling performance compared to traditional electrode materials.

Use CasesContent extracted from patent full text and abstract with AI.

• Rechargeable lithium-ion batteries for portable electronics such as smartphones, laptops, and tablets.
• High-performance batteries for electric vehicles (EVs).
• Batteries for energy storage systems in renewable energy grids (solar, wind, etc.).
• Power sources for aerospace and medical devices requiring stable, high-capacity batteries.
• Development of next-generation lithium-ion cells for industrial applications.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved cycling stability with reduced capacity fading over time.
• High specific charge/capacity and efficient lithium ion intercalation.
• Lower irreversible charge loss, resulting in high coulombic efficiency (greater than 99%).
• Combines benefits of transition metal oxides (stability) and sulphides (lower voltage and high capacity).
• Potential to extend battery lifetime and enhance performance in demanding applications.
