SIB具有研究前景
Cathode
layered transition metal oxide
polyanionic compound
Prussian blue analoge
......
Anode
(challenge because of huge-volume-change)
Mechanism
Alloying reaction—Li/ Na with Si/ Sb/ Sn/ Zn/ In/ Bi/ Cd
Conversion-type—abundant & nontoxic
nanocomposite with carbon—Durability but
sacrificing specific capacity
Capacity
(thick) SEI—excessive consumption electrolyte
solvent
salt
electrode
additive
small netural molecules
decrease the bulk [Na+] & increase interface impedance
anion
specific element rich SEI
CATION
This work
Double Electrical Layer Tailored
core-shell/ hollow structure—high ICE but
poor capacity retention
Intercalation mechanism—graphite/ hard carbon/ TiO2
