Silicon (Si) has turned out to be a promising active material for next‐generation lithium‐ion battery anodes. Nevertheless, the issues known from Si as electrode material (pulverization effects, volume change etc.) are impeding the development of Si anodes to reach market maturity. In this study, we are investigating a possible application of Si anodes in low‐power printed electronic applications. Tailored Si inks are produced and the impact of carbon coating on the printability and their electrochemical behavior as printed Si anodes is investigated. The printed Si anodes contain active material loadings that are practical for powering printed electronic devices, like electrolyte gated transistors, and are able to show high capacity retentions. A capacity of 1754 mAh/g_Si is achieved for a printed Si anode after 100 cycles. Additionally, the direct applicability of the printed Si anodes is shown by successfully powering an ink‐jet printed transistor.

量身定制的印刷锂离子阳极硅/碳化合物

事实证明，硅（Si）是下一代锂离子电池阳极的有希望的活性材料。然而，以硅作为电极材料的已知问题（粉碎效应，体积变化等）阻碍了硅阳极的发展以达到市场成熟度。在这项研究中，我们正在研究Si阳极在低功率印刷电子应用中的可能应用。生产了量身定制的Si油墨，并研究了碳涂层对可印刷性及其作为印刷Si阳极的电化学行为的影响。印刷的Si阳极包含活性物质负载，该活性物质负载可为诸如电解质门控晶体管之类的印刷电子设备供电，并且能够显示出高容量保持率。容量1754 mAh / g_硅100个循环后，对于印刷的Si阳极可达到λ。此外，成功地为喷墨印刷晶体管供电，显示了印刷硅阳极的直接适用性。
