Lithium battery will become the future cheap power storage options

9 January 9 (xinhua) British imperial college forecast, to a new study released in the coming decades, lithium ion battery in most scenarios, it is expected to become the power stored in the cheapest choice.

of imperial college, the team set up a model that is used to analysis between 2015 and 2050, nine power storage technology in cost change trend of 12 kinds of application scenarios, including large batteries, pumped storage power station, etc. Related work has been published in the American journal of joule.

study shows that the current pumped-storage power station is the most cheap way of electricity storage, the use of power load is low excess electricity supremacy of pumping water reservoir, and then when needed, through the water to the reservoir to generate electricity.

but team predicts that over time, the cost of the pumped storage power station will not fall further, and the cost of lithium-ion battery will continue to reduce, expected since 2030 in most application scenarios, which are the cheapest power storage options. By 2050, the lithium ion battery cost advantage will be more obvious.

report's main authors, imperial college scholar oliver & middot; Schmidt said, the future lithium ion batteries due to low cost and performance advantages, will occupy the advantage in the vast majority of the power system applications.
