Solid Composite Polymer Electrolytes for High Energy Density and Safe Lithium Metal Cells

摘要

Nowadays,electrical energy storage is one of the most critical issue to answer global warming by effectively replacing fossil energies by renewable ones.The Li-ion technology,widely studied and available on the market for multiple application is now reaching its limits and does not represent alone a viable option toward energetic transition.Therefore,one option currently under study is the use of metallic lithium as anode both in Li-ion cells and in the so-called"post Li-ion technologies".In this perspective,lithium metal anode represents the"holy grail"of battery research for its extremely high theoretical specific capacity(3860 mA h g~(-1)),the lowest redox potential(-3.040 V vs the standard hydrogen electrode)and a low gravimetric density(0.534 g cm~(-3)).
