Increasing Demand

The ever-increasing demand for high-capacity rechargeable batteries highlights the need for sensitive and accurate diagnostic technology for determining the state of a cell, for identifying and localizing defects, and for sensing capacity loss mechanisms. Here, we leverage atomic magnetometry to map the weak induced magnetic fields around Li-ion battery cells in a magnetically shielded environment. The ability to rapidly measure cells nondestructively allows testing even commercial cells in their actual operating conditions, as a function of state of charge. These measurements provide maps of the magnetic susceptibility of the cell, which follow trends characteristic for the battery materials under study upon discharge. In particular, hot spots of charge storage are identified. In addition, the measurements reveal the capability to measure transient internal current effects, at a level of μA, which are shown to be dependent upon the state of charge. These effects highlight noncontact battery characterization opportunities. The diagnostic power of this technique could be used for the assessment of cells in research, quality control, or during operation, and could help uncover details of charge storage and failure processes in cells.

Nanostructured Metal

The aligned freestanding nanorods (NR) of Co3O4 and nanoporous hollow spheres (NHS) of SnO2 and Mn2O3 were investigated as the anodes for Li-ion rechargeable batteries. The Co3O4 nanorods demonstrated 1433 mAh/g of reversible capacity initially and then decreased gradually. The NHS of SnO2 and Mn2O3 delivered energy densities as 400 and 250 mAh/g, respectively, in multiple galvonastatic discharge–charge cycles. The morphologic changes of the nanostructure anodes were investigated. It was found that Co3O4 NR broke down during cycles, but SnO2 NHS still maintained their structural integrity in multiple cycles resulting in sustainable high capacity. The nanostructured metal oxides exhibit great potential as the new anode materials for Li-ion rechargeable batteries with high energy density, low cost, and inherent safety.
