“…It is a less expensive technology than rare materials used in gas-sensing applications [3]. Therefore, it has been utilized in various applications, including: solar energy cells [4], optoelectronics [5], catalysis [6][7][8], biosensors [9][10][11][12][13], photoelectrochemical sensors [14,15], supercapacitors [16], lithium ion batteries [17,18], infrared photo detectors [19], electrochemical sensors [20,21], and gas sensors. Figure 1b shows the number of papers published from 1995 to now, where CuO was studied.…”

In this work, the latest achievements in the field of copper oxide thin film gas sensors are presented and discussed. Several methods and deposition techniques are shown with their advantages and disadvantages for commercial applications. Recently, CuO thin film gas sensors have been studied to detect various compounds, such as: nitrogen oxides, carbon oxides, hydrogen sulfide, ammonia, as well as several volatile organic compounds in many different applications, e.g., agriculture. The CuO thin film gas sensors exhibited high 3-S parameters (sensitivity, selectivity, and stability). Furthermore, the possibility to function at room temperature with long-term stability was proven as well, which makes this material very attractive in gas-sensing applications, including exhaled breath analysis.

“…The chemical state of LiCu 2 O 2 and LiCu 3 O 3 was studied using XPS ( Figures 3A-F). Their XPS core-level spectra of Cu 2p comprise intense spin-orbit split peaks for 2p 3/2 (934.1 eV) and 2p 1/2 (954.2 eV) accompanied by satellite peaks (939-945 eV and 959-964 eV), which are typical of Cu II valency (Zatsepin et al, 1998;Momeni and Sedaghati, 2018). Besides, the remaining two main fitted peaks center at 932.4 and 952.5 eV, representing Cu 2p3/2 and Cu 2p1/2 of Cu I , respectively (Wang et al, 2018;Zhou et al, 2018).…”

The thermal battery has been designed to be active at high temperature to satisfy storage life and large capacity for storage and emergency power. The development of thermal battery with high specific energy requires that the cathode has high thermal stability and excellent conductivity. Here, the semiconductor material Li-Cu-O compounds LiCu 2 O 2 and LiCu 3 O 3 are synthesized by a simple solid-phase sintering technique, which is simpler than the traditional synthesis process. The thermal decomposition temperatures are 680 • C and above 900 • C, respectively. This work first applies the Li-Cu-O compounds to the thermal battery. With a cutoff voltage of 1.5 V, the specific capacities of LiCu 2 O 2 and LiCu 3 O 3 are 423 and 332 mA h g −1. Both the decomposition temperature and specific capacity are higher than in the commercial FeS 2 and CoS 2 , especially LiCu 2 O 2. This work affords an alternative of the cathode materials for high specific capacity thermal battery.
