水系電解液和離子液體電解液區(qū)別 已有2人參與

我理解水系電解液也是水作為溶劑,里面有離子存在,離子液體電解液不也是這樣的組成嗎?請(qǐng)問(wèn)水系電解液和離子液體電解液具體在組成上是有什么區(qū)別嗎? 網(wǎng)上搜到的都是兩者功能上的區(qū)別,但組成、定義的區(qū)別劃分并沒(méi)有,這個(gè)問(wèn)題應(yīng)該是太過(guò)于基礎(chǔ)了,見(jiàn)笑了,還望不吝賜教,謝謝! |

| 應(yīng)該是很好的問(wèn)題,從基礎(chǔ)上進(jìn)行討論。水系和離子液體電解液的本質(zhì)區(qū)別是溶劑,一個(gè)是水,一個(gè)是有機(jī)電解液,類似EC, DMC等等。至于離子與組分,商品型的基本確定組分,而好多是研究階段,研究各種組分影響。至于兩者的比較,感覺(jué)有一點(diǎn)兒是肯定的,電位窗口,水系的不超過(guò)2V,同時(shí)會(huì)導(dǎo)致水解而生成氫氣與氧氣,安全性也是問(wèn)題,而有機(jī)電解質(zhì),更高,同時(shí)更穩(wěn)定。不過(guò),開(kāi)拓水系電池,也是研究的一部分。 |

An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C (212 °F). While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions. These substances are variously called liquid electrolytes, ionic melts, ionic fluids, fused salts, liquid salts, or ionic glasses. [1][2][3] Ionic liquids have many potential applications. They are powerful solvents and can be used as electrolytes. Salts that are liquid at near-ambient temperature are important for electric battery applications, and have been considered as sealants due to their very low vapor pressure. |
