A team at Argonne National Laboratory has used spatially resolved energy dispersive X-ray diffraction to obtain a “movie” of lithiation and delithiation in different sections of a Li-ion battery cell and to quantify lithium gradients that develop in a porous graphite electrode during cycling at a 1C rate (full discharge in 1 hour).

As described in an open access paper in Nature Communications , the target material (Li[Li 0.144 Ni 0.136 Co 0.136 Mn 0.544 ]O 2 , denoted as LR-NCM) delivers a discharge capacity as high as 301 mAh g −1 with initial Coulombic efficiency of 93.2%. —Qiu et al. The researchers prepared LR-NCM using a co-precipitation method.

The team suggests, in a paper published in the ACS journal Nano Letters , that the results, showing rechargeable sodium-ion batteries with a comparable performance to current Li-ion batteries, could push NIBs as a cost-effective alternative for next-generation post-lithium batteries. The GQD coating provides both sensitization and protection.
