The solar scientists are developing cheaper sodium battery: cost for lithium battery only 1%

Reference news network on July 16, Russian media reported, Russia and Germany, the researchers found that can be used with special structure of sodium replacement rare and expensive lithium-ion batteries. Using new technology to make the sodium battery lithium battery low cost than it is now widely used, but capacity is no less. At present, made from sodium and graphene the multilayer structure of the battery is in test phase.

according to the Russia today television website reported on July 15,, by al quarter & middot; Carat shed ning professor who led the international team of scientists wrote in the journal nano energy, solar power network, using a special multilayer structure sodium battery instead of lithium battery technology are expected to test a success. The team assembled a number of scientists, they respectively come from Russia, the Russian academy of sciences biochemical institute of physics, national technical university in Germany HZDR research center and the German Max & middot; The Max Planck institute.

the team's work is before the German experts research of: on the basis of the study showed that if the lithium ion between the two layers of graphene and formation of three layers structure can significantly increase the battery capacity.

the author, the Russian state technical university researcher elias & middot; Cut stuck he said in an interview with Russia today television reporters & other; With lithium ions and graphene three layer structure of lithium battery, capacity is 828 mah/g, solar energy, is a traditional graphite anode of lithium battery ( 372 mah/g) More than twice. ”

the researchers say, is widely used in the manufacture of lithium battery is a rare and expensive metal. Sodium ion battery costs only about one percent of the lithium ion battery, because of low cost, abundant sodium itself, solar portal, and its chemical property means that available light and cheap aluminum instead of copper as a battery and auxiliary materials. Therefore, sodium ion batteries far below the cost of a lithium-ion battery.

modeling test results show that the solar energy equipment, a new three layers structure of sodium ion battery capacity per gram and traditional graphite anode of lithium ion battery, which is about 335 mah/g.
