Title: | Correction: Chatterjee, A.; et al. Transition metal hollow nanocages as promising cathodes for the long-term cyclability of Li–O2 batteries. Nanomaterials 2018, 8, 308 | Authors: | Chatterjee, A Or, SW Cao, Y |
Issue Date: | 2018 | Source: | Nanomaterials, 2018, v. 8, no. 10, 748 | Abstract: | The authors wish to add the following information to this paper [1]. The last paragraph of Section 1 in the Introduction has been replaced by the following two paragraphs: One of the drawbacks of using these spinel structured oxides is their low surface area [12]. In our previous work [16], we have announced the preliminary results and initial observations on the basic morphology and magnetism of a highly porous spinel-type, Mn3O4, called Mn3O4 hollow nanocages (MOHNs), in addition to the general electrochemical performance of MOHNs/Ketjenblack (KB) cathode-based Li-O2 batteries. It has been demonstrated that the use of a simple facile template assisted growth technique is capable of producing crystalline paramagnetic MOHNs composed of many 25 nm mean diameter Mn3O4 nanoparticles, loosely agglomerated together to form the shell of a mesoporous hollow nanocage structure with a large mean diameter of 250 nm and a high surface area of 90.65 m2·g-1. Moreover, the resulting MOHNs/KB cathode-based Li-O2 batteries exhibit more than 50 discharge-charge cycles at a reversible restrained specific capacity of 600 mAh·g-1 and a specific current of 400 mA·g-1. This paper is extended from the previous proceedings paper [16]. It broadens the previous focus on the physical aspect of MOHNs to the physicochemical aspect of MOHNs. We thereby provide a more comprehensive evaluation and elaboration on the physicochemical properties and formation mechanism of MOHNs, as well as the electrochemical performance of MOHNs/KB cathode-based Li-O2 batteries. An analysis of death batteries is also performed, in order to understand how the mesoporous hollow nanocage structure of MOHNs provides a pathway for better diffusion of reactants and products, how it prevents the blockage of pores from Li-O2, and how it improves the cyclic stability of Li-O2 batteries. | Publisher: | Molecular Diversity Preservation International (MDPI) | Journal: | Nanomaterials | ISSN: | 2079-4991 | DOI: | 10.3390/nano8100748 | Rights: | © 2018 by the authors.
