example

[0040] Combination 27 (BCI standard battery size) PbC hybrid energy device employs approximately 680ml of sulfuric acid electrolyte, the Combo 27 has five negative electrodes containing 82 parts activated carbon, 10 parts carbon black and 8 parts PTFE; 6 positive electrodes containing lead and 10 partitions each having a thickness of 0.5 mm. Due to the structure of the negative electrode, the amount of sulfuric acid electrolyte absorbed and carried is 92.5% of the limited absorption capacity of sulfuric acid electrolyte.

[0041] A conventional Group 27 lead-acid battery employing 735ml of sulfuric acid electrolyte has 8 negative electrodes comprising lead / lead sulfate active material, 7 positive electrodes comprising lead dioxide and 14 each with a 2mm thickness of the divider. The amount of sulfuric acid electrolyte absorbed and carried is 72% of the limited absorption capacity of sulfuric acid electrolyte. Existing common sense suggests that the use of 10 partitions of 0....

Abstract

A hybrid energy storage device has at least one lead-based positive electrode and at least one carbon-based negative electrode, a separator between the electrodes, a casing which will contain the electrodes and separator, and an acid electrolyte. The separator is gas permeable, and is capable of absorbing and entraining acid electrolyte. The separator has a finite capacity for absorption of acid electrolyte, and the quantity of acid electrolyte which is present in the cell is less than the finite capacity of the separator. Upon assembly of the cell, the casing is sealed, and there is no liquid acid electrolyte within the assembled cell.

Description

[0001] This International Application claims priority to Application Serial No. 11 / 876,005, filed October 22, 2007, with the United States Patent and Trademark Office. technical field [0002] The invention relates to a hybrid energy storage device comprising at least one battery having at least one positive electrode, at least one negative electrode, a gas-permeable separator, an acidic electrolyte and a housing. The amount of acidic electrolyte placed within the at least one cell is less than the limited absorption capacity of the gas permeable separator, at least one positive electrode, and at least one negative electrode for acidic electrolyte. Background technique [0003] Hybrid energy storage devices, also known as asymmetric supercapacitors or hybrid batteries / supercapacitors, combine battery electrodes and supercapacitor electrodes to produce A device with a unique set of features including operability. Hybrid lead carbonate energy storage devices use an acid lead ...
