LITHIUM SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18285007 titled 'LITHIUM SECONDARY BATTERY
Simplified Explanation
The abstract describes a lithium secondary battery with a wound type electrode group, a core member, and a nonaqueous electrolyte. The negative electrode allows for lithium metal deposition and dissolution, with a space in the electrode group for the separator to be apart from the electrodes.
- Positive electrode, negative electrode, and separator make up the wound type electrode group.
- Core member inserted in the hollow of the electrode group.
- Nonaqueous electrolyte with lithium ion conductivity.
- Lithium metal deposits and dissolves in the negative electrode during charging and discharging.
- Space in the electrode group for the separator to be apart from the electrodes.
Potential Applications
The technology can be applied in:
- Electric vehicles
- Portable electronic devices
- Energy storage systems
Problems Solved
- Improved battery performance
- Enhanced safety features
- Increased energy density
Benefits
- Longer battery life
- Faster charging capabilities
- Higher energy efficiency
Potential Commercial Applications
- Battery manufacturing companies
- Electric vehicle manufacturers
- Consumer electronics companies
Possible Prior Art
One possible prior art could be the development of lithium-ion batteries with similar electrode configurations and lithium metal deposition/dissolution mechanisms.
Unanswered Questions
How does the technology impact battery recycling processes?
The article does not address the potential effects of this technology on battery recycling processes. It would be interesting to explore how the presence of lithium metal in the negative electrode affects the recyclability of these batteries.
What are the environmental implications of using nonaqueous electrolytes in these batteries?
The abstract does not discuss the environmental impact of using nonaqueous electrolytes. Further research could investigate the sustainability of this choice and any potential drawbacks in terms of environmental pollution or resource depletion.
Original Abstract Submitted
A lithium secondary battery includes a wound type electrode group including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, a core member inserted in a hollow of the electrode group, and a nonaqueous electrolyte having a lithium ion conductivity, wherein in the negative electrode, a lithium metal deposits during charging and the lithium metal dissolves during discharging, and the electrode group has a space that allows the separator to be apart from and oppose at least one of the positive electrode and the negative electrode.
