在一個資訊發展蓬勃的現代，鋰電池在現代科技中是非常重要的存在，無論是通訊手機、純電汽車、筆記型電腦、心律調整器…等等。鋰電池不但有高容量、重量輕、能量密度高等等，但是在鋰電池的電解液選擇上，就必須嚴格選擇，有些電解液可以儲存較多能量，但是可能就有起火燃燒甚至爆炸的危險。離子液體是一個低揮發、高導電性、高熱穩定的液態鹽，適合作為電解液的使用。本篇論文研究，Bis(trifluoromethane) sulfonimide Lithium與Triethylene glycol dimethyl ether混和成的Li[TFSI]G3和Lithium trifluoroacetate與Triethylene glycol dimethyl ether混和成的Li[TFA]G3，結構變化。在常壓光譜可觀察到在G3上有853.02cm-1上有訊號，但是隨加入的Li[TFSI]增多，會發現訊號逐漸分成2訊號，在高壓實驗下，發現G3的受壓力影響，波數從2880.00cm-1到2885.79cm-1，但是加入Li[TFSI]之後，發現加入Li[TFSI]越多，波數從2888.1cm-1到2889.30cm-1 ，可以觀察到Li[TFSI]讓G3有穩定的效果。另一個Li[TFA]G3中，發現Li[TFA]與Li[TFSI]有相同效果，可以將G3穩定。

In a tech-flourishing modern time, lithium battery plays a crucial role in contemporary technology. Installed in cellphones、pure electric cars、laptops、heart rate regulators among others, lithium battery has many advantages of high capacity、light weight、high power density and so on. However, when you are choosing a lithium battery, you have to do it strictly. Some electrolyte can store much more power, but it may cause a fire even an explosion. Ionic liquid is liquid salt which has low volatility、high conductivity、high thermal stability, suitable for being electrolyte. The essay focuses on Li[TFSI]G3 mixed by Bis(trifluoromethane) sulfonimide Lithium and Triethylene Glycol dimethyl ether and Li[TFA]G3 mixed by Lithium trifluoroacetate and Triethylene glycol dimethyl ether.Li[TFA]G3 mixed from dimethyl ether has structural changes. There is a signal detectable at 853.02cm-1 on atmospheric pressure spectrum. Nevertheless, with the increasing amounts of Li[TFSI], you would find that it can be divided into two signals. During a high pressure experiment, you could dicover that G3 affected by pressure ranges from 2800.00 cm-1 to 2885.79cm-1. yet, when Li[TFSI] added, you will find that the more Li[TFSI] you add, the more stable G3 will be at 2888.1cm-1 to 2889.30cm-1. Likewise, in Li[TFA]G3, you can find that Li[TFA]and Li[TFSI] has the same effect of stabilizing G3.
