A versatile electrode fabrication strategy based on electrospinning combined with airbrush–spraying (ECAS) is developed for the preparation of composite paper electrodes. The LiFePO 4 paper electrodes (ca. 13 mg cm −2 ) display good cycling stability with a capacity decay of only 15 % over 300 cycles at 1 C for lithium‐ion batteries. It is also demonstrated that the ECAS technique can obtain ultrahigh areal capacities of 12.3 mAh cm −2 using electrodes with an extra‐high areal loading of LiFePO 4 paper (>75 mg cm −2 ). A full cell is constructed with ECAS LiFePO 4 paper as the cathode and ECAS Li 4 Ti 5 O 12 paper as the anode.
