An Advanced Lithium-Ion Battery Based on a Graphene Anode and a Lithium Iron Phosphate Cathode
We report an advanced lithium-ion
battery based on a graphene ink
anode and a lithium iron phosphate cathode. By carefully balancing
the cell composition and suppressing the initial irreversible capacity
of the anode in the round of few cycles, we demonstrate an optimal
battery performance in terms of specific capacity, that is, 165 mAhg<sup>–1</sup>, of an estimated energy density of about 190 Wh kg<sup>–1</sup> and a stable operation for over 80 charge–discharge
cycles. The components of the battery are low cost and potentially
scalable. To the best of our knowledge, complete, graphene-based,
lithium ion batteries having performances comparable with those offered
by the present technology are rarely reported; hence, we believe that
the results disclosed in this work may open up new opportunities for
exploiting graphene in the lithium-ion battery science and development
