Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a monolithic integrated solid-state sodium ion battery. Background Art

[0002] Monolithic integrated solid-state sodium-ion battery is a new type of battery technology. It integrates solid electrolyte, positive electrode material and negative electrode material in a single sheet structure. It is not a multi-layer stacked structure. This design can reduce the volume and weight of the battery and improve the energy density of the battery. It has high safety and long cycle life. The most important point is that sodium resources are abundant, the damage to the environment is small, and the processing process is relatively environmentally friendly.

[0003] Although the existing monolithic integrated solid-state sodium ion batteries have many advantages in use, they still have certain shortcomings. That is, monolithic integrated solid-state sodium ion batteries are generally used in groups to form battery packs, and when the batteries are installed on the battery carrier, they need to be fixed one by one to achieve full installation. The operation is cumbersome and not convenient enough. In order to meet the requirements of volume and size, the battery carrier structure is generally set to be relatively compact. As a result, when one of the batteries fails and needs to be replaced, it is more troublesome to disassemble it due to the limitations of the battery carrier structure. Moreover, when it is not working and needs to be transferred or stored, there is a lack of appropriate protective mechanisms, which makes the battery susceptible to accidental damage.
