A lithium battery structure is provided. The lithium battery structure includes a first metal layer including aluminum foil or stainless steel foil, a second metal layer including copper foil, nickel foil or stainless steel foil, a separator, a first electrode layer, a second electrode layer, and a first functional layer including a first composition. The separator is disposed between the first metal layer and the second metal layer. The first electrode layer is disposed between the first metal layer and the separator. The second electrode layer is disposed between the second metal layer and the separator. The first functional layer is disposed between the first metal layer and the first electrode layer. The first composition includes 20-80 parts by weight of flake conductive material, 1-30 parts by weight of spherical conductive material, 10-50 parts by weight of thermoplastic elastomer and 1-25 parts by weight of nitrogen-containing hyperbranched polymer.
