[[alternative]]Study on Pile-up and Roll-up Types of Lithium Iron Cells

碩士電機工程學系[[abstract]]摘要 由於全球相關汽車工業、發電工業、零售業及建築業都開始積極投入綠化運動，且能源價格急遽飆升，促使許多行業積極朝向再生能源發展，而在再生能源市場主要可分為兩大部份，一部份為太陽能發電，另一部份為儲能區塊，而在儲能區塊內鋰鐵電池(LiFeXMYPOZ)的應用日趨被青睞，這是因為它的10 倍數以上的充放電電流倍率及達近千次循環週期。而鋰鐵電池因不同的製作流程主要可分為採捲繞型及堆疊型電池芯，本論文將對這兩種型態的鋰鐵電池利用充放電實驗比較彼此容量的差異。實驗結果發現，鋰鐵堆疊型電池芯在相同容積空間可得一較大的電容量，並可延長電池操作時間。[[abstract]]ABSTRACT Several industries, such as global automobile industry, electricity generation industry, retail trade, and construction industry, have aggressively developed green energy because the energy price is rapidly soaring. The energy market can be grouped in two categories in recent years: one is solar energy and the other is storage energy. In the storage energy category, a lithium polymer battery (LiFeXMYPOZ) has received much attention because it has almost thousand periods of charge/discharge cycles. The lithium battery cell has two types, pile-up and roll-up, and their difference mainly comes from manufacturing procedure. In the thesis, the capacities of the two types of the lithium battery are compared with charge/discharge experiments. From the obtained results, it is found that the pile-up type has a larger capacity and a longer usage time as compared to the roll-up type of the lithium battery. Keywords: lithium polymer battery, pile-up battery cell, roll-up type battery cel
