Current Status and Future Perspectives of Lithium Metal Batteries
2 1 – The “holy grail” Li anode: brief history, early failures and future targets of rechargeable Li-metal batteries 4 Since the mid-20th century, metallic Li has been of high interest for high energy density batteries. In particular, its high theoretical gravimetric capacity of 3861 mAh g–1, and the most negative standard reduction potential (–3.040 V vs. standard hydrogen electrode
