Scalable fabrication of a large-area lithium/graphene anode towards a long-life 350 W h kg−1 lithium metal pouch cell

A thermally initiated conversion method with facile fabrication procedures for Li/graphene composite anode is reported, and a 2.6 A h pouch cell employing this anode delivers a high energy density of 356 W h kg −1 and a long lifespan of 100 cycles.
