SOLID-STATE SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18363755 titled 'SOLID-STATE SECONDARY BATTERY
The abstract describes a solid-state secondary battery that can minimize chemical degradation during charging and discharging processes. The battery consists of a laminate body with a positive electrode layer, solid electrolyte layer, and negative electrode layer, as well as two types of solid electrolytes - one with oxidation resistance and the other with reduction resistance.
- The first solid electrolyte content is higher than the second solid electrolyte in the positive electrode layer.
- The first solid electrolyte content is higher than the second solid electrolyte in a specific region of the positive electrode layer.
- The second solid electrolyte content is higher than the first solid electrolyte in a specific region of the negative electrode layer.
Potential Applications: - Energy storage for electric vehicles - Portable electronic devices - Grid energy storage systems
Problems Solved: - Chemical degradation during charging/discharging - Enhanced battery performance and longevity
Benefits: - Improved battery efficiency - Longer lifespan - Safer operation
Commercial Applications: Solid-state batteries could revolutionize the electric vehicle industry by providing longer-lasting and safer energy storage solutions. This technology could also be utilized in various portable electronic devices and grid energy storage systems.
Questions about Solid-State Secondary Batteries: 1. How do solid-state secondary batteries differ from traditional lithium-ion batteries? Solid-state secondary batteries use solid electrolytes instead of liquid electrolytes, which can enhance safety and prevent leakage issues.
2. What are the key advantages of using solid-state secondary batteries in electric vehicles? Solid-state batteries offer higher energy density, longer lifespan, and improved safety compared to traditional lithium-ion batteries.
Original Abstract Submitted
A solid-state secondary battery is provided which can suppress chemical degradation from charging/discharging. A solid-state secondary battery includes a laminate body made by a positive electrode layer, solid electrolyte layer and negative electrode layer being laminated, and a first solid electrolyte having oxidation resistance and a second solid electrolyte having reduction resistance, in which content of a first solid electrolyte is greater than a second solid electrolyte in a solid electrolyte contained in the positive electrode layer, content of the first solid electrolyte is greater than the second solid electrolyte in a solid electrolyte contained in a region on a side of the positive electrode layer of the solid electrolyte layer, and content of the second solid electrolyte is greater than content of the first solid electrolyte in a solid electrolyte contained in a region on a side of the negative electrode layer of the solid electrolyte layer.
