Estimation of Power Output of Li Batteries Using Room Temperature Ionic Liquids (RTILs) Electrolytes

been attracting much interest as a novel electrolyte material containing no organic solvent. A demand for increasing the energy density of the Li-ion battery has been so strong in order to make the electric devices and hybrid vehicles more useful. As the energy density becomes higher, more serious damage could be expected as a result of the accident. And cells and modules should be in strict control in order to avoid thermal runaway. RTILs can be characterized by outstanding thermal stability and authors have found the possibility to improve the safety to some extent 1. AQA-amide RTILs, like N-methyl-N-propylpiperidinium bis (trifluoromethanesulfonyl) amide (PP13[TFSA]) suppressed heat evolution from a small Li peace and Li0.5CoO2 separated by glass fiber with electrolyte up t
