A Review of Degradation Mechanisms and Recent ...
Oxygen-redox-active (ORA) layered oxide cathodes for sodium-ion batteries have received considerable attention due to their ultrahigh capacity. However, the voltage decay during electrochemical cycling in such materials is still elusive and unsolved, which seriously limits their practical implementation. Her
Although significant progress has been made on the cycle life of silicon (Si)-based lithium (Li)-ion batteries (LIBs), their calendar life is still far less than those required for electrical vehicle applications. Here, the fundamental mechanisms behind the limited calendar life of Si-LIBs were systematically investigated. It is found that …
New anode materials that can deliver higher specific capacities compared to the traditional graphite in lithium-ion batteries (LIBs) are attracting more attention. In this chapter, we discuss the current …

A review of nuclear batteries
Moreover, the overlap between p orbitals (oxygen) and d orbitals (transition metal) in the band structure of LRCMs results in TM–O bonding and TM–O* antibonding bands, manifesting both metal and ligand characteristics [23].The electronic configuration of O 2− contains one 2 s (inactive) and three 2p (active) doublets. . Normally, all three 2p …
