Is fpcspe a safe battery?

To further confirm safety during battery operation, a folding experiment was conducted. The assembled pouch cell could operate an LED light even when folded over 90° The brightness of the LED lights did not change during the process of folding and restoring of folding, indicating that FPCSPE has good flexibility and high safety.

What is the leakage current of fpcspe battery?

In contrast, the leakage current of the battery using FPCSPE does not exceed 10 μA until 4.8 V.

How does the FPC PCBA work?

At the end of the flexible PCBA for the battery cell contact system, we print the QR code on the FPC assemblies so that they are traceable. The users or battery pack manufacturers can scan the code to know all the details of the FPC PCBA and materials' origins. The FPC assembly is finished now. Next, the FPC assemblies are placed on a jig.

What is FPC & why is it important?

Simultaneously, the advancement of battery integration technology and the increased demand for automation in large-scale production are leading to the gradual replacement of traditional wiring harness solutions with integrated and lightweight FPC (Flexible Printed Circuit) solutions.

Is fpcspe a good battery for high-voltage cathodes?

In contrast, more than 70% of the capacity of the battery using FPCSPE 3–40 was maintained after 300 cycles, and the coulombic efficiency was almost 99.6%, which demonstrates the excellent electrochemical stability and good compatibility between FPCSPE and high-voltage cathodes.

What is the difference between Fermi energy level and FPC?

Based on the ultraviolet photoelectron spectra, the work function values of FPC and PANI were 3.8 and 2.0 eV, respectively, whereas the Fermi energy level (EF) values were located at 1.31 and 0.25 eV for FPC and PANI, respectively (Fig. S5 (b), (c)) .
