本人由于時間緊張,發(fā)150金幣求高手幫忙翻譯一下以下文字,謝謝 由圖5可見,添加未經(jīng)任何處理AC的電極,其對應(yīng)的氧化電流要比經(jīng)過特定處理后的電極所對應(yīng)的氧化電流要大,而且該電流峰對應(yīng)的積分電量(放電容量)呈現(xiàn)減少的趨勢。對上述現(xiàn)象可進(jìn)行如下解釋:活性炭顆粒中存在大孔、中孔、微孔三種不同類型的孔,其中對于電極放電容量影響最大的是中孔,而現(xiàn)在的三種試樣中,中孔的量出現(xiàn)了較大幅度的變化,在(b)、 (c)試樣中,有大量的中孔被鉛粉或氧化鉛粉吸附,從而堵塞了部分孔隙結(jié)構(gòu),導(dǎo)致電極中中孔比例下降。圖5中還可以觀察到,在-0.2V附近,理應(yīng)放電結(jié)束,電流幾乎變?yōu)榱,但目前的情況是電極仍然以一定的氧化電流持續(xù)一段時間,即電極多放出了一定的電量。根據(jù)電極反應(yīng)原理分析,推測此處的電流可能來自于高比表面活性炭與硫酸電解液所形成的固液相雙電層電容放電。 |

| As shown in figure 5, oxidation current of the modified electrode with the untreated AC was much bigger than that modified with treated AC. Furthermore, a obvious reduce of corresponding Integral power(discharge capacity) was presented. the possible reason was following: there are three types of activated carbon particles: macropore,mesopore and micropore. the discharge capacity of the electrode was matters most withthe mesopore. in here, the amountof the mesopore was substantial changes in the three samples. a large number of mesopore was clogged with lead powder or oxidation adsorption lead oxide, which blocked part of the pore structure, leading to the drops of the percentage of mesopore on the electrode in the in (b), and (c) sample. discharging process should be ended near 0.2 V(current almost to zero), but continue currentstill last for a period of time (more rechangeing)be observed as shown in Figure 5. According to the electrode reaction principle , speculated that the current may come from high surface and electrolyte activated carbon sulfuric acid formed by solid liquid electric double layer capacitance discharge. |
