Recently, researchers at Stanford University to create a pure lithium-ion batteries, allows electric cars to run 480 km, achieving a lithium-ion battery technology leap.

What is pure lithium batteries?

In the study published in the journal Nature Nanotechnology, we can find the answer.

Lithium-ion batteries on the market today should specifically say "electrolysis of lithium battery", State of simply as electrolyte for lithium (lithium-ion) are present. This battery has three major components, namely: electrolyte provides electronic, accepted a discharge in anode and cathode, respectively.

According to Professor Yi Cui of Stanford University's materials science and Engineering Department explains, can all be used for anode materials of lithium is undoubtedly the most promising, some people call it the "Holy Grail" because lithium has inherent advantages--light weight, small size and high efficiency.

But scientists years to finally put the "Holy Grail" into reality. Stanford team to solve this very difficult scientific problem, realized placing the lithium anode.

The "Holy Grail"-luxury experience

In this recent technological breakthroughs in the Stanford research team said they used nanotechnology to create a pure lithium batteries.

United States Energy Secretary Steven Chu (Steven Chu) is one of the members of the research team.

"If we can will power density increased to three times times, while put cost reduced one-fourth, this will is exciting of results," Chu said, "we will has three times times Yu existing battery range capacity of phone, and single times charging driving mileage over 300 miles, and price only 25,000 dollars of pure electric--key is driving took experience than each gallons fuel mileage 40 Michael (mpg) of car more rod. ”

"Holy Grail" of technological breakthroughs

Anode material, usually silicon and graphite, reacts during the charging process will "eat" the electronic and lithium reactions are generally more severe, would eat more electronic, thermal expansion is not uniform.

In addition, the anode and electrolyte contacts will release a lot of heat and chemical reactions between lithium anode and electrolyte electrolyte consumption and shorten battery life.

To overcome three obstacles, Stanford researchers designed and built a honeycomb micro-isolation layers – called "nanoparticles"--so that we can create a flexible insensitive film, participate in the reaction of lithium to avoid instability.
