Aluminum textile-based binder-free nanostructured battery cathodes using a layer-by-layer assembly of metal/metal oxide nanoparticles (vol 8, 011405, 2021)

Abstract

The authors correct the discussion paragraph related to Eqs. (1) and (2) from the original article1 in order to incorporate correct information. It is preferable to define the R0 value as the resistance at the transition temperature of aluminum and the R0 value as the preexponential factor. The last paragraph on p. 4, which continues to the end of the left column on p. 5, should read as follows: A notable advantage of our approach is that, despite the use of only 4 bilayers of metal NPs, the resultant electrodeposited textile electrode can exhibit bulk metal-like electrical conductivity while maintaining the highly porous structure of the native polyester textile without metal agglomeration. To further investigate the electrical transport, the electrical resistivity of the Al-ETs was measured with a physical property measurement system by increasing the temperature from 2K to 300K at a heating rate of 10K/min [Fig. 2(d)]. The electrical resistivity linearly increased as the temperature increased, which is a typical metallic characteristic. In other words, the temperature coefficient (a) in the relation shown in Eq. (1) was positive, showing the electrical behavior of metal. The relation is expressed as follows: (Farmula Presented) where DR is the change in resistance fromR0 (X), R0 is the resistance at transition temperature (X), a is the temperature coefficient (K-1), and T is the absolute temperature (K). Additionally, the electrical transport behavior of the Al-ETs was found not to follow the hopping conduction model (Fig. S13 in the supplementary material), which can be expressed by the following equation: (Farmula Presented) where r is the conductivity at T K, R0 is the pre-exponential factor, A is a constant, T is the absolute temperature, and d is the dimensionality (d=3 in the hopping mechanism). © The Author(s), 2021.
