1Biodegradable magnesium/iron batteries with polycaprolactone encapsulation:A microfabricated power source for transient implantable devices显示文摘This study presents the design,fabrication,and testing of biodegradable magnesium/iron batteries featuring polycaprolactone(PCL)as a packaging and functional material.The use of PCL encapsulation minimized the electrochemical cell volume and supported longer discharge lifetimes and higher discharge rates than state-of-the-art biodegradable batteries.Specifically,the electrodes were separated and insulated by a 5μm-thick PCL layer that served as both a battery packaging material and a permeable coating for physiological solution to penetrate and activate the battery.A systematic investigation of the electrode size,discharge rates,electrolyte selection,and polymeric coating revealed the critical reactions and phenomena governing the performance of the Mg-based biodegradable batteries.Comparison with previous reports on biodegradable batteries and medicalgrade non-degradable lithium-ion batteries demonstrated the superior performance of PCL-coated Mg/Fe batteries at these size scales,which exhibited an energy density of 694 Wh kg^(−1) and a total volume of 0.02 cm^(3).Melissa Tsang Andac Armutlulu Adam W.Martinez Sue Ann Bidstrup Allen Mark G.Allen 2015Microsystems & Nanoengineering2015,1,1:0
