Large energy storage applications require ultimate safety, economical manufacturing and full recyclability of the batteries. HE3DA lithium battery technology platform with 3-D electrode architecture meets all these demands. The 3D cell construction, together with ceramic composite separator increases battery safety by orders of magnitude. Easy disassembling and separating of the materials after the life end of the battery makes recycling a profitable secondary source of battery materials. Recycling of this type of battery already meets parametres set for 2050.Main features of this technology and 3D cell parameters produced in the commercial production will be discussed. Advantages of these cells in large energy storage units will be demonstrated. Figure 1
