NEGATIVE ELECTRODE FOR LEAD-ACID BATTERY AND MANUFACTURING METHOD THEREOF Russian patent published in 2009 - IPC H01M4/20 H01M10/06 

FIELD: electricity.

SUBSTANCE: invention refers to electrical industry and can be used for manufacture of lead-acid batteries. According to invention, electrode includes current collector, terminal and active mass. Current collector consists of two nets connected to each other. On surface of nets there located is carbon layer. Terminal is located between nets. Upper edges of nets are above terminal plank and connected to each other. Each of the nets is made from two-layered material. Outer net layer is made from high-adhesive polymer, and inner layer is made from solid polymer or fibre glass or carbon. Ratio of active mass weight to current collector weight is 6.0-16.0. When manufacturing current collector, nets are put one on the other and terminal is arranged between them. Upper edges of nets are located above terminal plank. Then the nets are connected to each other and at the same time, their upper edges and nets with plank and eye of terminal are connected. Current collector elements are connected for example by welding or gluing. Then to current collector surface there applied is carbon layer, for example by thermal or gas flame method, and current collector cells are filled with active mass.

EFFECT: improving specific electrical characteristics.
