We report two-dimensional AgInP2Se6(AIPSe) bimetallic phosphorus trichalcogenides nanosheets as anodes for advanced alkali metal ion batteries (AMIBs). The intrinsic layered architecture of this compound not only facilitates rapid charge propagation but also accentuates ion storage due to its expansive surface area. The integration of the bimetallic component results in a synergistic enhancement in electronic/ionic conductivity and optimizes the redox dynamics of multi-electronic materials, eventually attaining superior electrochemical characteristics. Moreover, the accompanying deposition of metallic silver during electrochemical processes reduces battery polarization, while the presence of metallic indium acts as an efficacious structural stabilizer, effectively inhibit dendrite proliferation. As an anode electrode coupled with graphite (G) in lithium-ion (LIBs) and potassium-ion batteries (PIBs), AIPSe@G anodes for LIBs achieve 707.8 mA h g−1at 0.1 A g−1, retain over 900 cycles at 2.0 A g−1, and demonstrate 318.5 mA h g−1at 3.0 A g−1rate capability. For PIBs, they reach 480.3 mA h g−1at 25.0 mA g−1, sustains for 550 cycles at 250 mAg−1, and offers 214.2 mA h g−1at 3.0 A g−1rate performance. Comprehensive full cell tests further endure 100 cycles in both LIBs and PIBs under diverse current regimes. Our study pioneers a new direction for AMIB anode materials, emphasizing the advantages of integrating bimetallic features into two-dimensional frameworks to boost electrode dynamics and achieve consistent conversion reactions.

Due to the need of developing point-of-care testing, measurement devices should be small in size and light in weight. In tradition, the measurement device usually need an additional bulky pump to inject the sample into it. So the requirement of additional bulky pump is the problem to be overcome when developing POCT device. In our work, the result successfully showed a multifunction micro-pump with low power consumption. This micro-pump possesses two critical functions, which are sample pumping and particle trapping. The most important of all is this micro-pump is quiet small within a total area of 1mm2, which means it has the potential to be integrated with corresponding sensors or other measurement devices. In summary, this micro pump is a good choice to develop as one part of POCT device with sample pumping and particle trapping (selecting) functions.
