    Abstract: A method and system to quickly analyze and predict battery failure and short-circuit comprises a battery cell unit carried with a sensor unit continuing detect a value of a condition of the battery cell unit to obtain a time domain result. The system will further convert the time domain result into a frequency domain result and will send an alarm or warning if such frequency domain result has exceeded a pre-set threshold. The present invention could accurately send the reminder or warning of the upcoming short-circuit at earlier stage of the battery cell unit by simply analyzing the time domain result converting as the frequency domain result. The system provided by the present invention has the ability to detect micro-circuit of the battery cell unit to facilitate detecting battery failure and short-circuit to avoid any emergency happened to the battery while using.

    Abstract: The present invention provides an additive containing sulfide-based solid electrolyte having an acidic component attached to the sulfide-based solid electrolyte. The sulfide-based solid electrolyte comprises a —PS structure having at least a phosphorous atom and a sulfur atom. The acidic component carries a positive charge which could firmly attach to the sulfur atom of the —PS structure of the sulfide-based solid electrolyte. The present invention utilizes the acidic component as the additive to enhance the water or vapor resistance ability to the sulfide-based solid electrolyte. By using compatible acidic component, the additive could firmly attach to the sulfur atom of the —PS structure of the sulfide-based solid electrolyte but still maintaining in good electrical properties. By enhancing the sulfur atom of the —PS structure of the sulfide-based solid electrolyte, the present invention could benefit the mass production for such material.

    Abstract: Present invention is related to a method and system to quickly analyze and predict battery failure and short-circuit. The system comprises a battery cell unit carried with a sensor unit continuing detect a value of a condition of the battery cell unit to obtain a time domain result. The system will further convert the time domain result into a frequency domain result and will send an alarm or warning if such frequency domain result has exceeded a pre-set threshold. The present invention could accurately send the reminder or warning of the upcoming short-circuit at earlier stage of the battery cell unit by simply analyzing the time domain result convecting as the frequency domain result. The system provided by the present invention has the ability to detect micro-circuit of the battery cell unit to facilitate detecting battery failure and short-circuit to avoid any emergency happened to the battery while using.
