本研究分兩部分第一部分為利用聚(N-乙烯甲醯胺)做為非水溶液電池正極高分子黏著劑。由於PNVF可溶於水的特性，因此可利用水作為正極漿料的分散劑，達到綠色環保的極片製成，並且PNVF可以降低電荷轉移阻抗使極化現象降低、PNVF為非結晶高分子不會阻鋰離子傳導、比PVDF還低的有機溶液溶脹特性使電極於電解液中不會因溶脹產生結構壞，除上述之外PNVF還有擁較PVDF強的附著力，能降低生產時的不良率並可製作出較厚的 電極與增加循環穩定性，這些特點使PNVF具有取代商用PVDF的潛力。本論文將利用電化學的方式來探討PNVF其降低極化現象的因素。
第二部分為含聚N-乙烯甲醯胺之水溶液膠態電解質。傳統水溶液電池雖然有導電度比有機溶液高、安全、對環境友善以及降低成本等優點，但缺點是電化學穩定窗口太過狹窄，導致工作電壓太低。本論文藉由將"polymer in salt"和"water in salt"的概念結合在一起，形成一種以水作為塑化劑之膠態電解質，其具有類似rubber type的物性，並能增加電化學穩定窗口，以及在室溫下充放電的特性。

The first part of this study is the use of poly(N-vinyl formamide) as a binder for non-aqueous lithium ion batteries. We can use water instead of organic solvents to disperse the slurry and thus provide a green battery cell assembly process. PNVF can reduce the charge transfer impedance to reduce polarization phenomenon, and the electrochemical experiments show that the internal resistance drop of PNVF system is smaller than the PVDF system (PNVF system: 1 C-rate,≒0.1 V vs Li/Li+). When 5 C-rate, we can have 100 mAh/g capacity and 3.3 V vs Li/Li+ discharge voltage. PNVF is a noncrystalline polymer and therefore does not block ion transport. In addition to the above, PNVF has a stronger adhesion force than PVDF (PNVF system: 2.5 N, PVDF: 0.8 N), which can increase cycle stability. These characteristics make PNVF have the potential to replace commercial PVDF.
The second part is poly(N-vinyl formamide) used as a gel type aqueous electrolyte in aqueous lithium ion batteries. Although traditional aqueous batteries have the advantages of higher conductivity, safety, environmental friendliness and lower cost than organic solutions, their disadvantages are the electrochemical stability window is too narrow, which cause the low operating voltage. In this paper, by combining the concepts of "polymer in salt" and "water in salt", a gel type electrolyte with water as plasticizer is formed, which has similar properties to rubber type. It can increase the electrochemical stability window, and the batteries can charge and discharge at room temperature.
