Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
1. Claims 1, 2 and 10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Tour et al. (US20210257679).
2. Regarding claims 1, 2, and 10, Tour teaches Aan early warning method for dendrite formation in a lithium battery (We report here a detection system capable of alerting for Li dendrite formation in a two-electrode battery with no additional electrodes required [0005]; That insurance system would act as a sensor and be able to detect Li dendrite formation when the battery is being used, such that it can send a signal to the battery management system, warning of the presence of Li dendrites [0008]), comprising: acquiring real-time operating condition information and electrochemical parameters of the lithium battery (When Li dendrites grow long enough to reach the RP coating, there will be a noticeable electrochemical response in the voltage profile with respect to time [0104]);
performing a computational simulation based on the real-time operating condition information and the electrochemical parameters through an electrochemical model (The system is therefore adapted to simulate the full-charging model at the high current needed for dendrite detection based on the normal charge curve at a lower current before performing a dendrite-detection process [0146]), and obtaining by analysis a deposition result of the lithium battery (The RP coating can be formed using various techniques, including but not restricted to spray coating, and physical/chemical deposition [0151]; The voltage decrease indicated by the arrow in FIG. 1D is the electrochemical response generated when Li dendrite contacts the RP coating [0073]); and using the deposition result obtained through electrochemical model simulation (This indicates that the RP coating was indeed responsible for the dramatic voltage change in FIG. 1D [0112]), providing early warning for the dendrite formation in the lithium battery (The detectable electrical response signal generated can be a change in voltage with respect to time during the charging of the battery [0024]; The test method further includes issuing a dendrite-detection signal if the charging voltage reaches a threshold voltage before the expected charge timing [0049]).
2. The method of claim 1, wherein the performing the computational simulation based on the real-time operating condition information and the electrochemical parameters through the electrochemical model (The system is therefore adapted to simulate the full-charging model at the high current needed for dendrite detection based on the normal charge curve at a lower current before performing a dendrite-detection process [0146]) comprises: simulating a relationship between a lithium plating amount and an overpotential of the lithium battery based on the real-time operating condition information and the electrochemical parameters through the electrochemical model (The fact that the voltage stayed >5 V for more than 6 min in the P-fc revealed another advantage of using an overpotential instead of detecting short circuits with a conductive interlayer [0119]; High resistance is often an obvious reason for having an overpotential in batteries. Therefore, the mechanism was studied in half-cells where the impact of the cathode can be avoided [0121]).
