6 FAQs about [Applying pressure on solid state li battery]
What is a good stack pressure for a solid-state lithium battery?
SSLB, solid-state lithium metal battery. From the engineering point of view, the target stack pressure values should be ideally <0.1 MPa (a few MPa may also be technically acceptable) to meet industrial-scale production requirements 126, whereas the stack pressure in most current SSLB studies (>10 MPa) is much higher than this.
Can stack pressure improve the development of solid-state batteries?
The development of solid-state batteries has encountered a number of problems due to the complex interfacial contact conditions between lithium (Li) metal and solid electrolytes (SEs). Recent experiments have shown that applying stack pressure can ameliorate these problems.
How much pressure is needed for a solid-state battery?
Particularly, a pressure of at least 3 kPa is required for a better contact for a current of 0.1 mA/cm 2, while at least 1 MPa pressure is needed to improve the interface under a current of 2.0 mA/cm 2.
