Li-Ion Batteries Involving Ionic Liquids

The high rate capability of LiFeP04 was evaluated in polymer-IL and compared to the pure IL cells configuration. The power performance was decreased when the polymer is added, at C/10 only 126 mAh g was dehvered compared to 155 mAh g .

Prediction of salt electrochemical stability in the context of Li-ion batteries has mainly involved predicting the Eox of novel lithium salt anions, frequently without any focus on the subsequent decomposition reaction products and mechanisms. However, with recent results on oxidation promoted solvent-anion reactions [57] and the rapid development of solvent-free ionic liquid (IL) electrolytes, investigations of both anion and cation decomposition products are foreseen by us to become more frequent and important - particularly in connection with the passivation phenomena at the negative electrode. As for solvents, we will here follow the historical development of studies and methods, followed by some more recent works that together with our remarks outline our perspective on the future.
