Solid-state solar container battery structure

What is a solid state battery?

Solid-state batteries consist of multiple solid–solid interfaces within the cathode, solid electrolyte, and anode, which can degrade or lose contact during cycling. These contact issues become more pronounced when the battery components experience significant volume changes throughout the charge–discharge process.

Do solid state batteries have a separator layer?

A separator layer is present between both electrodes, which enables ion transport while preventing electrical contact between the electrodes. On the contrary, solid-state batteries do not have any separator layer between the electrodes as they use solid electrolytes that separate the electrodes.

Do solid state batteries have a long cycle life?

Despite advancements in both lithium- and sodium-based solid electrolytes, challenges remain in achieving long cycle lifetimes and high power densities (27–31). Solid-state batteries consist of multiple solid–solid interfaces within the cathode, solid electrolyte, and anode, which can degrade or lose contact during cycling.

What is a solid-state battery (SSB)?

Solid-state batteries (SSBs) employ solid electrolytes in place of the liquid- or gel-type electrolytes used traditionally in Li-ion batteries. The solid electrolytes have improved thermal and chemical stability, hence eliminating safety concerns which are normally associated with liquid electrolytes, including flammability and thermal degradation.
