Lithium-ion batteries used in solar power generation more efficient than the lead-acid battery

The university of Southampton and Lithium ion batteries technology companies through joint research and development company's system proves that the lithium battery than lead-acid batteries for more efficient energy storage units.And their systems in the company's founder is a former researcher at the university of Southampton, arguably, the discovery is the common achievements of Southampton university teacher and pupil cooperation.

Researchers from the university of Southampton institute of sustainable energy, the purpose of the study is that I wish to use lithium-ion batteries as a photo voltaic system of energy storage device.In the company's system is responsible for providing research and development funds and battery management system, the battery management system can be used to read the institute needs all kinds of data.

In order to obtain first-hand information institute need, between the two sides have developed a target-oriented LiFePO4 battery and then connect the lithium batteries and photo-voltaic system, experiment, pv systems installed on the university buildings, this is the typical environment conducive to the test.

Through to the battery management system on the various data collection and processing, study three conclusions: 1, the lithium battery power efficiency is 95%, compared to 80% of lead-acid battery;2 high specific energy, lithium ion battery weight, which makes it lighter than lead-acid batteries of the same capacity weight;3, the energy storage battery a longer service life, can achieve 1600 charge-discharge cycles, the lower the cost of energy storage battery.

Graduated from the university of Brampton's system in the company founder, points out that, for all kinds of energy storage device plays an important role, it determines the energy use efficiency.Compared with the conventional lead-acid batteries, lithium iron phosphate batteries more efficient, service life is longer, lighter weight, lower cost.The battery is expected to be widely used in photo voltaic systems, and other renewable energy systems.

Research at the university of Southampton is a trend of battery technology, lithium batteries from miniaturization is applied to the medium of the electric car use power lithium battery large energy storage devices, to follow the use of the application of the gradual path of capacity from small to large.According to the analysis, if the lithium battery can be widely used in energy storage system, the market capacity will be more than 10 times of the existing various dosage of lithium battery market., including China for the research and application of lithium battery for energy storage is also in the process of actively, byd in zhangbei county in hebei province the first energy storage power station is the first large scale application and is used for solar energy storage and power generation system of lithium battery has gradually spread.
