    • 近年來因應減碳排放，綠色電力被全球重視，但由於綠色能源不穩定的特性無法直接用於電網上，需經過儲存後在進行使用。空氣電池有極大的比電容量而備受矚目，唯其低電壓、低電流、較差之充放電穩定性限制其大規模使用於市場上。本研究以鑭鍶錳氧化物(La0.8Sr0.2MnO3)配合靜電紡絲（electrospinning）技術製作連續性一維的奈米纖維型陰極，利用鑭鍶錳氧化物在鹼性電解液中(KOH)中良好的穩定性與奈米纖維極大的比表面積，來達成充放電穩定性佳，且具有良好活性之電極，同時碳纖維也能當作載體提供導電性較差的鑭鍶錳氧化物一個良好的導途徑。

    實驗以聚丙烯腈(PAN)、鑭鍶錳氧(La0.8Sr0.2MnO3)、二甲基亞碸(DMSO)，經磁石攪拌器均勻攪拌後，以靜電紡織技術製備奈米纖維型陰極，當鑭鍶錳氧聚丙烯腈重量百分比為45%時，電場強度為10~10.5kV,紡絲距離16cm,流量 0.005ml/min,針頭號數 25Gauge,可得直徑約為300~500nm尺寸之連續奈米線，繼續以升溫速率3°C/min將製備完成的奈米纖維陰極在含氧環境中(30~300°C)進行穩地化反應並持溫1hr，將經過穩定化處理過的纖維以3°C/min在氬氣氣氛中(300~900°C)進行碳化，並持溫1hr形成碳纖維與觸媒之複合陰極。

    將鑭鍶錳氧化物/碳纖維奈米纖維陰極進行電化學活性分析，分別測試半電池極化曲線及全電池充放電曲線。半電池極化曲線確認其ORR反應。接著進行全電池充放電循環穩定度分析，發現其庫倫效率經200次循環後維持近80%。

    In recent years green energy attracts lots of attention in the world owing to needing carbon emission reduction. Unstable properties make green energy not be able to be used directly for electricity grid. Green energy is always needed to be stored before using.
    High energy density makes Zn-air batteries be concerned. Nevertheless, low voltage and low current and low round-trip efficiency limited deployment in market. This research uses electrospinning to form LSM (La0.8Sr0.2MnO3) one-dimensional continuous nanofiber cathode. We used both high stability of LSM in the alkaline electrolyte(KOH) and nanofiber high surface area to build high cycle stability and high activity cathode. Carbon fiber can be used as a carrier to supply LSM, which has poor conductivity a good pathway to conduct electronic.
    This research uses LSM (La0.8Sr0.2MnO3) and Polyacrylonitrile (PAN) stirred with dimethyl sulfoxide (DMSO) to make nanofiber cathode by electrospinning method. When the weight percent of LSM (La0.8Sr0.2MnO3)/Polyacrylonitrile (PAN) was 45wt% using field voltage 10 ~ 10.5kV, working distance 16cm, flow rate 0.005ml/min, number of pin 25 Gauge, creating a uniform size about 300~500nm diameter continuous fiber. The cathode was heated from 30°C to 300°C with 3°C/min in air holding temperature on 300°C 1hr to stabilize, then heated to 300°C~900°C with 3°C/min in an argon atmosphere to be carbonized then stayed at 900°C for 1hr to form cathode catalyst.
    The electrochemical properties of nanofiber cathode were analyzed by half-cell polarization curve and charge/discharge tests, Linear Sweep Voltammetry(LSV) confirmed that the cathode has ORR activity and its coulombic efficiency was maintained at 80 % after 200 times charging/recharging cycles.
