Abstract
Small 2018, 14, 1703811 DOI: 10.1002/smll.201703811 In the originally published article, the units of energy density and power density were presented incorrectly in Figure 6c and related sentences. The correct figure and related text are presented herein. The correction of related sentences: In the abstract (line 14), “The aqueous device shows a high energy density of 15.48 mWh cm−2 at the power density of 0.6 KW cm−2. The solid-state device shows a high energy density of 14.72 mWh cm−2 at the power density of 0.6 KW cm−2” should be corrected to “The aqueous device shows an energy density of 15.48 μWh cm−2 at the power density of 0.60 mW cm−2. The solid-state device shows an energy density of 14.72 μWh cm−2 at the power density of 0.60 mW cm−2”. In the second paragraph on Page 6 (line 10), “The aqueous device showed high energy density of 15.48 mWh cm−2 at the power density of 0.6 KW cm−2. Furthermore, the solid-state device demonstrated high energy density of 14.72 mWh cm−2 at the power density of 0.6 KW cm−2” should be corrected to “The aqueous device showed an energy density of 15.48 μWh cm−2 (55.72 mWs cm−2) at the power density of 0.60 mW cm−2. Furthermore, the solid-state device demonstrated an energy density of 14.72 μWh cm−2 (52.99 mWs cm−2) at the power density of 0.60 mW cm−2”. The detailed calculation process is as follows. For aqueous device: The discharge time of the aqueous device is 199.40, 92.90, 42.00, and 14.45 seconds at the current density of 0.5, 1.0, 2.0, and 5.0 mA cm−2, respectively. The specific capacitance calculation formula according to galvanostatic charge-discharge curves is C = (idensity × ∆t)/∆V. Here, idensity is the discharge current density (mA cm−2), Δt is the discharge time (s), and ΔV is the value of the discharging voltage window (V). The discharging voltage window is 1.2 V. The specific capacitance of the aqueous device at the current density of 0.5, 1.0, 2.0, and 5.0 mA cm−2 was calculated to be 83.1, 77.4, 70.0, and 59.8 mF cm−2, respectively. For flexible device: The authors apologize for any inconvenience that miscalculation may have caused.
