Abstract

A battery core and a method of manufacturing the same are disclosed herein. The battery core includes a first electrode plate and a second electrode plate. The first electrode plate includes a substrate and a first active material. A first portion of the first active material is formed on a first area of the substrate, and a second portion of the first active material is formed on a second area of the substrate. The second electrode plate includes first and second substrates disconnected from each other, and a second active material. The first and second substrates are positioned corresponding to the first and second first areas respectively. A first portion of the second active material is formed on the first substrate, and a second portion of the second active material is formed on the second substrate.
