Provided are a non-woven fabric current collector and a method and system of fabricating a battery using the same. An electrode according to an embodiment of the present invention includes a non-woven fabric current collector including a conductive non-woven fabric sheet including a network of conductive fibers and pores for communication between a main surface and the interior thereof; and conductive patterns partially blocking the pores on the main surface of the conductive non-woven fabric sheet.

A battery grid is disclosed. The battery grid includes a pattern of grid wires. The pattern includes a grid wire having a first segment with a first corrosion resistance and a second segment with a second corrosion resistance which is less than the first corrosion resistance. The second segment corrodes at a rate which is faster than the corrosion rate of the first segment so as to dynamically release internal stress and control grid growth of the battery grid during its service life. A battery includes said grid and a method of forming said grid are also disclosed.

Bipolar plates for a lead acid battery and bipolar plate stack assembly comprising such plates is described. In another aspect, the subject matter describes, a lead acid battery comprising such bipolar plate stack assembly.
摘要:
An anode comprises one or more sheets of expanded zinc mesh. The thickness and mesh size of the expanded zinc mesh may vary. A single sheet of zinc mesh may be coiled, forming continuous electrical contact with itself. Alternatively, a single sheet of yinc mesh may be folded into layers, each layer in electrical contact with its adjacent layers. A third alternative is the use of two or more sheets of zinc mesh anodes are combined with a casing, a cathode, an electrolyte solution, and a separator between the cathode and anode to manufacture electrochemical cells.
