【摘要】：近年來(lái),我國(guó)提出優(yōu)化運(yùn)輸能源消費(fèi)結(jié)構(gòu),加大新能源、清潔能源車輛在城市公交和客貨運(yùn)輸領(lǐng)域的應(yīng)用。而鋅鎳電池具備綠色環(huán)保的特點(diǎn),因而得到了廣泛的研究。鋅鎳電池具有較高的工作電壓、較高的能量密度、使用安全和造價(jià)低等優(yōu)點(diǎn),具備了作為電動(dòng)汽車電池的條件。對(duì)于鋅鎳電池的研究開始于100多年前,但由于使用過(guò)程中出現(xiàn)的鋅枝晶、溶解及鈍化和毒害鎳正極等問(wèn)題,成為鋅鎳電池市場(chǎng)化應(yīng)用的障礙。本論文以鋅鹽在堿性電解液中的溶解性較小的特性為出發(fā)點(diǎn),采用懸浮液反應(yīng)法在不同條件下用氧化鋅和氫氧化鈣反應(yīng)制備鋅酸鈣,并對(duì)其性能進(jìn)行研究。采用懸浮液反應(yīng)法在不同溫度、不同表面活性劑、不同堿濃度的條件下制備鋅酸鈣,并研究了上述相關(guān)條件對(duì)鋅酸鈣形貌、粒徑、收率的影響,采用光學(xué)顯微鏡、掃描電子顯微鏡(SEM)、X射線衍射分析(XRD)、熱重分析和粒徑分析等手段對(duì)鋅酸鈣樣品進(jìn)行了表征分析。結(jié)果表明,通過(guò)XRD和熱重分析,可以證實(shí)我們成功地制備了鋅酸鈣。制備溫度、KOH濃度、表面活性劑對(duì)鋅酸鈣的形貌、收率和粒徑均有影響。采用EDTA滴定法考察了溶解溫度、溶解時(shí)間、介質(zhì)濃度、鋅酸鈣粒徑、鋅酸鈣制備溫度和表面活性劑對(duì)鋅酸鈣在KOH溶液/NaOH溶液中溶解性的影響,并對(duì)不同條件制備的鋅酸鈣樣品進(jìn)行電化學(xué)性能研究。結(jié)果表明,鋅酸鈣在KOH溶液/NaOH溶液中溶解性隨著溶解溫度的升高而增大;隨著溶解時(shí)間的增加先增大后趨于飽和;隨著介質(zhì)濃度的增大而增大;隨著鋅酸鈣粒徑的增大而減小;隨著鋅酸鈣制備溫度的升高而增大。通過(guò)對(duì)比鋅酸鈣樣品和氧化鋅作為負(fù)極模擬電池的放電平臺(tái)以及容量保持率,發(fā)現(xiàn)鋅酸鈣作為負(fù)極無(wú)論是在放電平臺(tái)還是充放電容量保持率均優(yōu)于氧化鋅。
[Abstract]:In recent years, China has proposed to optimize the energy consumption structure of transportation, increase the application of new energy and clean energy vehicles in the field of urban public transport and passenger and freight transportation, while the zinc-nickel battery has the characteristics of green and environmental protection. Therefore, Zn-Ni battery has been widely studied. It has the advantages of high working voltage, high energy density, safe use and low cost, and has been used as a condition for electric vehicle battery. The research on Zn-Ni battery began more than 100 years ago. However, due to the problems of zinc dendrite, dissolution, passivation and poisoning of nickel positive electrode in the process of use, it is an obstacle to the market-oriented application of zinc nickel battery. In this paper, the characteristics of zinc salt solubility in alkaline electrolyte are taken as the starting point. Calcium zincate was prepared by the reaction of zinc oxide with calcium hydroxide under different conditions by suspension reaction, and its properties were studied. Calcium zincate was prepared under different alkali concentrations. The effects of the above conditions on the morphology, particle size and yield of calcium zincate were studied. The samples of calcium zincate were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetry (TG) and particle size analysis (TGA). The results showed that the samples were characterized by XRD and thermogravimetric analysis. It can be proved that we have successfully prepared calcium zincate. The preparation temperature and concentration of Koh, surfactant have influence on the morphology, yield and particle size of calcium zincate. The dissolution temperature, dissolution time, concentration of medium and particle size of calcium zinc acid have been investigated by EDTA titration. The effects of preparation temperature and surfactant on the solubility of calcium zincate in KOH solution / NaOH solution were studied. The electrochemical properties of calcium zincate samples prepared under different conditions were studied. The solubility of calcium zincate in KOH solution / NaOH solution increases with the increase of dissolution temperature, increases first with the increase of dissolution time and then tends to saturation, increases with the increase of medium concentration, decreases with the increase of particle size of calcium zincate. With the increase of preparation temperature of calcium zincate, the discharge platform and the capacity retention of the cathode simulated battery were compared with the sample of calcium zincate and zinc oxide. It is found that calcium zincate is superior to zinc oxide in both discharge platform and charge-discharge capacity retention as negative electrode.
