ウム粉末或いは繊維との結合が単なる成型であるため、
結合力が不充分であることに起因すると考えられる。However, even when such a negative electrode substrate is used, as the number of charge/discharge cycles increases, phenomena such as pulverization and lithium-aluminum alloy being extracted from the porous body and falling off have been observed. This is because the porous material constituting the negative electrode substrate and the aluminum powder or fibers are simply bonded by molding.
This is thought to be due to insufficient bonding strength.
