We preconcentrate 2 M LiTFSI in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide inside a nanoporous alumina (AlO) layer as a so-called concentrated lithium semi-solid layer on a Cu current collector for anode-free Li-metal NMC90 batteries. This concept lowers the activation energy for lithium-ion transport and reduces the nucleation overpotential, enhancing the cycling stability.
我们将2M的双三氟甲烷磺酰亚胺锂盐（LiTFSI）在纳米多孔氧化铝（AlO）层内预浓缩，形成所谓的浓锂半固态层，置于用于无阳极锂金属NMC90电池的铜集流体上。这一概念降低了锂离子传输的活化能，减少了成核过电位，提高了循环稳定性。
