Ionic liquids show promise as an electrolyte in the next generation of Li-ion batteries

摘要

Researchers of Kansai Center of Na-Utional Institute of Advanced Industrial Science & Technology(AIST;Ikeda,Japan;edlinks.che.com/4517-545)have developed a new flame-resistant electrolyte,based on ionic liquids,for secondary lithium ion batteries that use metallic Li as the negative electrode.Although such batteries offer twice the energy density compared to conventional Li-ion batteries,they are prone to short circuiting due to the formation of dendrites after frequent charge-discharge cycles.
