▎ 摘  要

In recent decades, primary lithium batteries have served as the predominant power source for implantable medical devices. Among them, the lithium/silver vanadium oxide (SVO) primary battery with high safety and reliability is the only type of battery applied in implantable cardioverter defibrillators (ICDs). With the continuous progress of medical devices, the requirements on the batteries for long service life, light weight, and small size are increasing. Rechargeable lithium-ion batteries (LIBs), with high energy density and long life, are ideal power sources for advanced medical devices. However, the poor cyclability of SVOs greatly limits its practical application in rechargeable LIBs. Herein, a binder-free and free-standing alpha-AgVO3 nanowire/graphene oxide (alpha-AgVO3/GO) nanocomposite paper was fabricated through simple hydrothermal and vacuum filtration techniques. The electrochemical properties of the as-prepared alpha-AgVO3/GO nanocomposite paper as the free-standing cathode for LIBs were studied. The alpha-AgVO3/GO nanocomposite paper exhibits a high discharge capacity and a stable cycling performance. This strategy may offer an effective approach to exploring the SVO electrode structure of rechargeable LIBs for implantable medical devices.
