Storage battery and storage battery pack containing the storage battery

Abstract

The invention relates to a battery and a battery pack containing the battery. The storage battery of the present invention comprises at least one first electrode, at least one second electrode, a separator and an electrolyte, the first electrode and the second electrode are respectively in contact with the electrolyte, and the separator is arranged between the first electrode and the second electrode. The two electrodes are used to prevent the short circuit between the first electrode and the second electrode, and it is characterized in that at least one first auxiliary electrode with the same area as the first electrode is arranged in parallel outside the first electrode, and the first electrode The first auxiliary electrode is separated from the first auxiliary electrode by an insulating film; at least one second auxiliary electrode with the same area as the second electrode is arranged in parallel on the outside of the second electrode, and the second electrode is connected to the second auxiliary electrode. The electrodes are separated by an insulating film; the auxiliary electrodes are separated by an insulating film. The storage battery charging time of the present invention can be adjusted arbitrarily as required.

Description

technical field [0001] The invention relates to a battery and a battery pack containing the battery. Background technique [0002] With the deepening of awareness of environmental protection and energy saving, the rapid development of new energy electric vehicles has huge market potential; the development of the solar energy industry has a huge demand for batteries; the trend of changing traditional motorcycles to battery cars is obvious; the whole battery industry is thriving. [0003] Lithium-ion batteries have led the development direction of the battery industry with environmental protection and high efficiency, but the high cost of use and the shortage of raw materials have restricted the speed and scale of development; the development of high-pollution and low-efficiency batteries represented by lead-acid batteries has been restricted, but it has a low cost of use. most of the market share; therefore, technological innovations to them are of practical significance. ...

AI Technical Summary

Problems solved by technology

[0003] Lithium-ion batteries have led the development direction of the battery industry with environmental protection and high efficiency, but the high cost of use and the shortage of raw materials have restricted the speed and scale of development; the development of high-pollution and low-efficiency batteries represented by lead-acid batteries has been restricted, but it has a low cost of use. Most of the market share; therefore, technological innovations are of practical significance to them

[0004] Common lithium-ion batteries, lead-acid batteries, nickel-metal hydride batteries, etc. have different manufacturing materials, different electrical mechanisms, and different energy storage capacities, but they all have a common feature: long charging time, generally more than 8 hours; This has become a technical bottleneck for the development of the entire storage battery industry; fast charging is very meaningful to the entire storage battery industry
