Lab隨記

  經EC-Lab EIS成功擬合結果可得下表 藍色框框為deviation ( dev) 紅色框框為 error ratio ( X2/ I Z I ) 一般來說， dev偏差值要<1 ，但超過5個 elements的fitting, 後面 elements 的 dev都可以容許比較大一點，以這範例來說R2與R3 略大於1是OK的。 而   error ratio ( X2/ I Z I ) <0.1 。 一般在擬合時，會先看dev值是否<1，在查核 error ratio。 官方Youtube頻道參考影片:(影片標題及連結) Description of the fitting window – ZFit tutorial, part.4 - BioLogic Tips and tricks - ZFit tutorial, part.5 - BioLogic   ZSim and ZFit as learning tools.

 The rechargeable aluminum-ion battery (AIB) is a promising candidate for next-generation high-performance batteries, but its cathode materials require more development to improve their capacity and cycling life. We have demonstrated the growth of MoSe2 three-dimensional helical nanorod arrays on a polyimide substrate by the deposition of Mo helical nanorod arrays followed by a low-temperature plasma-assisted selenization process to form novel cathodes for AIBs. The binder-free 3D MoSe2-based AIB shows a high specific capacity of 753 mAh g–1 at a current density of 0.3 A g–1 and can maintain a high specific capacity of 138 mAh g–1 at a current density of 5 A g–1 with 10 000 cycles. Ex situ Raman, XPS, and TEM characterization results of the electrodes under different states confirm the reversible alloying conversion and intercalation hybrid mechanism during the discharge and charge cycles. All possible chemical reactions were proposed by the electrochemical curves and characterizat...

Transparent flexible energy storage devices are considered as important chains in the next‐generation, which are able to store and supply energy for electronic devices. Here, aluminum‐doped zinc oxide (AZO) nanorods (NRs) and nickel oxide (NiO)‐coated AZO NRs on muscovites are fabricated by a radio frequency (RF) magnetron sputtering deposition method. Interestingly, AZO NRs and AZO/NiO NRs are excellent electrodes for energy storage application with high optical transparency, high conductivity, large surface area, stability under compressive and tensile strain down to a bending radius of 5 mm with 1000 bending cycles. The obtained symmetric solid‐state supercapacitors based on these electrodes exhibit good performance with a large areal specific capacitance of 3.4 mF cm−2, long cycle life 1000 times, robust mechanical properties, and high chemical stability. Furthermore, an AZO/NiO//Zn battery based on these electrodes is demonstrated, yielding a discharge capacity of 195 mAh g−1 at a...

Aluminum–sulfur batteries (ASBs) have attracted substantial interest due to their high theoretical specific energy density, low cost, and environmental friendliness, while the traditional sulfur cathode and ionic liquid have very fast capacity decay, limiting cycling performance because of the sluggishly electrochemical reaction and side reactions with the electrolyte. Herein, we demonstrate, for the first time, excellent rechargeable aluminum–selenium batteries (ASeBs) using a new deep eutectic solvent, thiourea-AlCl3, as an electrolyte and Se nanowires grown directly on a flexible carbon cloth substrate (Se NWs@CC) by a low-temperature selenization process as a cathode. Selenium (Se) is a chemical analogue of sulfur with higher electronic conductivity and lower ionization potential that can improve the battery kinetics on the sluggishly electrochemical reaction and the reduction of the polarization where the thiourea-AlCl3 electrolyte can stabilize the side reaction during the revers...

在循環伏安法中，Randles–Sevcik方程描述了掃描速率對峰值電流ip的影響。 對於簡單的氧化還原反應，ip不僅取決於電活性物質的濃度和擴散特性，還取決於掃描速率。[1]  i  p  = 0.4463 n FAC（nFvD / RT） 1/2 或者，如果溶液溫度為25°C：[2]   ip = 268600 n  3/2  AD  1/2  Cv  1/2 ip =曲線鋒上最大電流（安培） n =氧化還原中轉移的電子數 A =電極面積，單位為cm2 F = C mol-1中的法拉第常數 D =擴散係數，單位為cm2 / s C =濃度（摩爾/立方厘米） ν=掃描速率，單位V / s  (計算時切記不要使用mV) R = VC K-1 mol-1中的氣體常數 T =以K為單位的溫度 ip以更快的電壓掃描速率增加。 重要的是要記住，電流i是每單位時間的電荷（或通過的電子）。 因此，在更快的電壓掃描速率下，每單位時間傳遞的電荷會更大，因此ip會增加，而電荷的總量是相同的。 用途 使用由該方程式定義的關係，可以確定電化學活性物質的擴散係數 。 對於已知（或可以估計）擴散係數的物種，ip相對於ν1/ 2的圖的斜率可用於計算其他參數 如電極面積 [1]  https://en.wikipedia.org/wiki/Randles%E2%80%93Sevcik_equation
