Researchers at the Chinese Academy of Sciences have developed all-3D printed lithium metal batteries with robust cycle stability and ultrahigh areal energy density., the scientists explain that the new LMBs take a porous and conductive Ti3C2Tx MXene skeleton for dendrite-free and a stable Li metal anode and multi-dimensionally conductive LiFePO4 lattice as an ultra-thick cathode.LMBs are considered high-energy-density systems beyond current state-of-the-art lithium-ion batteries.
As the new devices are comprised of a dendrite-free Li-metal anode with porous MXene lattices, they are able to regulate local current distribution, which homogenizes lithium nucleation. Their 3D conductive porous LFP framework cathode, on the other hand, achieves fast ion/electron transfer channels.
