Kukwanisa kuchaja kweElectrode yebhatiri ye lithium-ion yakadhindwa ne3D, iyo yakapetwa katatu kupfuura iyo yeelectrode yakagadzirwa nenzira yemazuva ose. Nzira yekudhinda ye3D inogadzirisa graphite nanoflakes muzvinhu kuti iwedzere kuyerera kwemaion e lithium mukati nekubuda muelectrode (tsvakurudzo yakataurwa pamusangano weACS Spring 2022).
