“…These systemshave been extensively investigated and used in a wide variety of electrochemical devices, such as batteries (e.g. lead-acid batteries [14] or lithium batteries [15,16]), electrochromic devices [17,18], fuel cells [19], supercapacitors [20], sensors and actuators [21], an dye-sensitized solar cells [13,22].Several polymeric materials have been studied as PE, such as poly(ethylene oxide), polyacrlylates or polymethacrylates [15,16] or silicates [14]. Natural polymers such as starch [23], chitosan [24], gelatin [25], pectin [26]or agar [17,18]have been used as gel polymer electrolyte (G-PE).…”

A novel gel polymer electrolyte cell for in-situ application of corrosion electrochemical techniques

Electrochemical techniques, such as electrochemical impedance spectroscopy (EIS), are widely used for corrosion studies. However, their applicability to studies on metallic cultural heritage has been less spread due to the usual need of performing measurements in-situ on sculptures or monuments. This paper presents the development of a gel polymer electrolyte (G-PE) cell to overcome the difficulties associated with the use of liquid electrolytes for in-situ measurements. 5% agar has been employed to gelify a 0.3 M NaCl electrolyte. Laboratory comparison has demonstrated that gelification with agar does not affect EIS results in a significant way. A robust and convenient electrochemical cell has been fabricated using this G-PE and has been successfully applied to obtain EIS data from a bronze sculpture in the National Archaeological Museum in Madrid (Spain).

Alternative configuration lithium cell exploits electrode and polymer electrolyte cast all‐in‐one to form a membrane electrode assembly (MEA), in analogy to fuel cell technology. The electrolyte is based on polyethylene oxide (PEO), lithium bis‐trifluoro sulfonyl imide (LiTFSI) conducting salt, LiNO3 sacrificial film‐forming agent to stabilize the lithium metal, and fumed silica (SiO2) to increase the polymer amorphous degree. The membrane has conductivity ranging from ~5×10−4 S cm‐1 at 90 °C to 1×10−4 S cm‐1 at 50 °C, lithium transference number of ~0.4, and relevant interphase stability. The MEA including LiFePO4 (LFP) cathode is cycled in polymer lithium cells operating at 3.4 V and 70 °C, with specific capacity of ~155 mAh g‐1 (1C = 170 mA gLFP‐1) for over 100 cycles, without signs of decay or dendrite formation. The cell exploiting the MEA shows enhanced electrochemical performance as compared with the one using simple polymeric membrane stacked between cathode and anode. Furthermore, the MEA reveals the key advantage of possible scalability and applicability in roll‐to‐roll systems for achieving high‐energy lithium metal battery, as demonstrated by pouch‐cell application. These data may trigger new interest on this challenging battery exploiting the polymer configuration for achieving environmentally/economically sustainable, and safe energy storage.
