磷酸鋰鐵電池於汽機車產業之應用與發展

全球因油價飆漲所造成的通貨膨脹壓力等景況，而處於石油增產以降低油價，但加速消耗地球寶貴資源，在此原油儲量易減難增的前提下，未來全球各國很有可能從重視庫存石油量，轉移到必須替代能源，如電池庫存的新境界。一般所稱的電池可以分為兩種，一種是蓄電電池(battery)，另一種則是發電電池(cell)，兩者皆具有節能的效果。目前如太陽能電池、燃料電池等，是藉由使用新的替代性能源發電減少石化燃料的使用來達到節能。本文所要探討的是透過轉換效率的提高來達到節能效果的二次電池，將聚焦在未來最具發展潛力的新一代鋰電池─磷酸鋰鐵電池。有鑑於動力來源由石化轉為電池，電動車輛主要發展與商機在將動力馬達、電池系統、車體結構、動力控制系統等，其他配套之電動壓縮機、電動煞車、快速充電系統等機電零組件等。本文將以磷酸鋰鐵電池為主軸，經由與不同能源的效益比對為出發點，延展至磷酸鋰鐵電池其供應鏈的結構分析與討論，進一步的找出磷酸鋰鐵電池在汽機車業中，具實質的優點，與適合的電池規格及應用方式。

Due to high oil prices and global wide high inflation, there are attempts to increase the oil production in order to contain the raise of oil prices from time to time. However these acts also accelerate the consumption of Earth’s precious resources. Under the premise of difficulty in maintaining high crude oil reserves, countries around the world are likely to shift their focuses from amount of crude oil reserves to alternative energy sources such as battery reverses. Generally speaking, there are two types of batteries, one of them is called battery which is applied in electrical energy storage, and the other type is called cell which is used for power generation. Both of them can improve the energy reused from the natural sources. For example solar cells, fuel cells, and etc. can be used as alternative energy sources to reduce fossil fuel emissions. By improving the efficiency of energy conversion, rechargeable batteries can achieve effective energy conservation. This study will focus on the new generation of lithium battery, LiFePO4, which is regarded as the most promising development in the future. There is trend for the automotive to be powered by electric; therefore there will be countless opportunities in developing effective electrical motor, battery system, electric car chassis, power control and other crucial components such as electrical compressor, electrical break system, fast battery charger system and etc. This thesis will prolog with LiFePO4 batteries in comparisons of different alternative technologies and their pros. and cons.; then expand to the analysis and discussions of its industrial value chains; and observe the positioning and development trends of LiFePO4 batteries in automotive industry.
