Abstract
The utility model relates to a lithium battery with monomer high-capability cells connected in parallel. The lithium battery with the monomer high-capability cells connected in parallel comprises a battery outer shell and a battery upper cover, wherein five sets of parallel electrodes and four anti-explosion plugs are arranged on the battery upper cover. Electrolyte solution used for electric cells of all electrodes is arranged in the battery outer shell. According to the lithium battery with the monomer high-capability cells connected in parallel, an integral battery pack scheme of gathering parts into a whole is adopted, the internal electrolyte solution can be shared for the electric cells of all sets of the electrodes, and the electrolyte solution is good in heat dissipation and cooling effect, and is recycled in a large battery shell space. Simultaneously, connection and inflation extrusion between the electric cells are avoided, so that the outer shell can not deform to scratch a plastic cover for fixing an electrode column, and therefore, poor sealing can not occur, and working efficiency and reliability of a battery set are improved, and manufacturing cost of the battery is reduced.
Description
Technical field
The utility model relates to a kind of lithium battery, particularly the parallel lithium battery of the large capacity battery core of a kind of monomer.
Background technology
Solar energy, wind power generation energy storage and new-energy automobile have become the high-tech industry of World Focusing, the appearance of national policies, planning and enforcement, indicate that China's energy storage and new-energy automobile industry will be faced with the historical optimum growth opportunity phase, the development of energy storage and new-energy automobile industry has risen to the national strategy height, and the environmental protection that the lithium ion battery group is generally acknowledged by people, harmless desirable storage battery.
At present, the lithium battery that solar energy, wind power generation energy storage and automobile are equipped with all adopts a large amount of single low capacity lithium batteries to carry out series-parallel mode to reach jumbo power requirement, owing to adopt the low capacity lithium battery of One's name is legion, so that the reliability of whole battery pack reduces, system's manufacturing cost is high, becomes the technical bottleneck that solar energy, wind power generation energy storage and new-energy automobile are promoted.
The utility model content
In order to overcome the deficiency of existing single lithium battery capacity, the utility model provides the large capacity battery core of a kind of monomer parallel lithium battery.
The technical scheme that its technical problem that solves the utility model adopts is: the parallel lithium battery of the large capacity battery core of monomer, include battery case and cell cover, and cell cover is provided with electrode and four explosion-proof plugs of five groups of parallel connections; Be provided with in the battery case for the shared electrolyte solution of the battery core of all electrodes.
Further, larger capacity scheme, adopting electrode in parallel is ten groups, explosion-proof plug is nine.
