Correction to “Insights into the thermopower of thermally regenerative electrochemical cycle for low grade heat harvesting"

Page 335. The last two energy densities W listed in Table 1 should be corrected. The energy density of NiHCF/Zn should be corrected from 5.6337 J/g to 5.8346 J/g. The energy density of NiHCF/ZnNH₃ should be corrected from 9.9502 J/g to 9.8912 J/g. Actually, the correct values (5.8346 J/g and 9.8912 J/g) were given in the main text of the paper on page 334. However, incorrect values (calculated with larger round-off errors in early version) were presented in the table. These corrections do not affect the discussions and conclusions as presented in the original publication. The authors would like to apologize for any inconvenience caused to readers.
