Why does lithium battery have long cycle life?

Now use the lithium battery, the longest life for 10 years or so. Earlier, Japan's sharp and Kyoto university professor Tian Zhonggong together successfully developed the service life of up to 70 years lithium ion batteries. The manufacture of lithium ion longevity battery, the volume of 8 cubic centimeters by using the latest simulation technology based on computer, optimize the iron and silicon anode materials used in combination.

From the perspective of the results of the experiments, the longevity of the lithium ion battery charge and discharge times of up to 25000 times, if calculated according to charge and discharge once a day, the service life of up to 70.And sharp said, the actual charge and discharge after 10000 times, its performance is still stable. Such calculations, a piece of the lithium ion battery service life will be 6 times. Even if with the combined use of renewable energy power generation device, even if the solar panels and wind turbines, batteries still can continue to use.

Researchers plan to the longevity of lithium ion battery application in wind and solar power, used as a large battery. At present, wind power and solar power are influenced by climate. Power output will change at any time. If cooperate with battery, can guarantee the stable output, reduce the influence of the grid to send. And frequent replacement battery, is raising the cost of power generation. If the 70 years of service life of the lithium ion battery application is to the above, will greatly reduce the cost of power generation.
