閥調式鉛酸蓄電池再生技術之研究

生產閥調密閉式鉛酸蓄電池的主要原物料是鉛錠，近年來隨著國際鉛價的上漲，對於國內許多公民營單位每年都需要更換大量的蓄電池而言，必須不斷的提高預算，在全球經濟不佳的情況下無疑是雪上加霜，本研究的目的是希望能夠透過電池再生的技術去延長電池壽命、降低成本、減少污染及節約能源。本研究選用高經濟價值的閥調鉛酸蓄電池來做再生而非一般汽車用的鉛酸蓄電池，因為閥調式鉛酸蓄電池在整個鉛酸電池市場的產值比重最高，拿來做再生較符合經濟效益且較有市場規模電池，再生的技術有很多種，但其再生原理都是一樣的，就是要將鉛酸電池裡的硫酸鉛晶體溶解後，使硫酸鉛還原至負極鉛板和正極二氧化鉛板。本研究在評估幾種再生技術後，最後選擇了鯊魚脈衝波的技術來做再生實驗，評估分析此再生技術在理論上是否合乎學理及邏輯；本研究會針對多組蓄電池來進行再生實驗，在實務上驗證再生後的電池性能是否符合線上使用規範，還是曇花一現只有短暫的成效。本實驗的結果證實，經過再生處理過的電池其放電效能確實比再生前提高數倍不等，如此一來，不論是在經濟成本和節能環保兩個層面皆有實質的貢獻及提升。

Lead ingots are used to produce valve-regulated sealed lead-acid batteries. As the price of lead has increased worldwide, various domestic public and private companies have been forced to increase their budgets to replace numerous batteries each year. In the disrupted global economic situation, this generates a budgetary challenge. In this study, regeneration technology was applied to extend battery life, reduce costs and pollution, and conserve energy. Instead of employing general automotive lead-acid batteries, the researcher regenerated valve-regulated lead-acid batteries, which account for the highest percentage of the total product value in the lead-acid battery market, facilitating economically beneficiary regeneration, and exhibiting market potential. The same regeneration theory is applied to various regeneration technologies. To regenerate lead-acid batteries, the lead sulfate crystals inside are dissolved and reduced to a negative lead electrode plate of lead and a positive lead dioxide battery plate of lead dioxide. After evaluating several regeneration technologies, the researcher employed the shark-pulse technique technology for the regeneration experiment and assessed its theoretical feasibility and logic. Regeneration experiments were conducted using multiple batteries, examining whether the regenerated batteries met actual usage requirements or demonstrated only temporary effectiveness. The experimental results showed that the discharge performance of regenerated batteries was many folds higher compared with pre-regeneration batteries. Therefore, battery regeneration technology substantially contributes to cost reduction, energy conservation, and environmental protection.
