==ALL-SOLID-STATE SECONDARY BATTERY AND METHOD OF CHARGING THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18163963 titled 'ALL-SOLID-STATE SECONDARY BATTERY AND METHOD OF CHARGING THE SAME

==Simplified Explanation==

The abstract describes an all-solid-state secondary battery with a cathode, an anode, and a solid electrolyte layer. The anode active material layer contains a material that can alloy with lithium or form a compound with lithium. The ratio of the initial charge capacity of the anode active material layer to the initial charge capacity of the cathode active material layer must satisfy a specific condition.

* The all-solid-state secondary battery includes a cathode, an anode, and a solid electrolyte layer.
* The anode active material layer contains a material that can alloy with lithium or form a compound with lithium.
* The ratio of the initial charge capacity of the anode active material layer to the initial charge capacity of the cathode active material layer must be between 0.01 and 0.5.
* The initial charge capacity of the cathode active material layer is determined from a first open circuit voltage to a maximum charging voltage.
* The initial charge capacity of the anode active material layer is determined from a second open circuit voltage to 0.01 volts vs. Li/Li.

Potential applications of this technology:

* Electric vehicles
* Portable electronic devices
* Renewable energy storage systems

Problems solved by this technology:

* Improves the performance and efficiency of all-solid-state secondary batteries
* Enhances the energy storage capacity and lifespan of the batteries
* Provides a safer alternative to traditional lithium-ion batteries

Benefits of this technology:

* Higher energy density
* Longer battery life
* Improved safety and stability
* Compatibility with various applications and devices


==Original Abstract Submitted==

An all-solid-state secondary battery including: a cathode including a cathode active material layer; an anode including an anode current collector, and an anode active material layer on the anode current collector, wherein the anode active material layer includes an anode active material which is alloyable with lithium or forms a compound with lithium; and a solid electrolyte layer between the cathode and the anode, wherein a ratio of an initial charge capacity (b) of the anode active material layer to an initial charge capacity (a) of the cathode active material layer satisfies a condition of Equation 1: 0.01 <(b/a)<0.5, wherein a is the initial charge capacity of the cathode active material layer determined from a first open circuit voltage to a maximum charging voltage, and b is the initial charge capacity of the anode active material layer determined from a second open circuit voltage to 0.01 volts vs. Li/Li.
