| Popis: | We propose a novel “bezel-less” lithium-ion battery (LIB) structure that enhances the volumetric energy density of LIB. This structure reduces the extra-space volume for seal and accumulation of current collectors, eliminating the bezel part by 16% compared to the conventional aluminum laminated LIBs. The bezel-less LIB using a Ni-rich positive electrode and a graphite negative electrode recorded an energy of 132 Wh and high energy density of 600 Wh L−1 (256 Wh kg−1). The safety of the proposed bezel-less LIB by a combined use of the quasi-solid-state electrolyte layer was successfully demonstrated in overcharge and collapse tests. |
