02 13:03 hits: first lithium battery breakthrough: no explosion, 500 times, is still valid for a long time, many scientists have been actively modified lithium ion battery, this limits the some mobile devices now.
According to foreign media reports, the Washington state university (
威诺娜州立大学)
Researchers put forward a kind of 'ideal', can replace the anode materials, and to a great extent, promote the development of lithium battery, it also brings to the lithium battery planning a new breakthrough.
In the process of charging and discharging, lithium ion can be moved back and forth between the two electrodes.
At that time, the main is a mixture of graphite and copper anode material, but scientists believe that there is great room for improvement.
Scientists say, pure lithium in solid material provides the highest energy density, if used as the anode, it can make the life extension of lithium-ion batteries, and store more energy.
In order to overcome the pure lithium metal anode around some security problems, the team will selenium sulfide and two kinds of additives into the battery cathode together, formed a layer of protective coating on the surface.
Practical tests show that this new type of battery can not only charge 500 times, but also to maintain a high efficiency.
(
This common protective layer in the process of circulation almost can not cause changes in the form of lithium anode, help reduce lithium dendrite growth and harmful side effects.
)
Scientists are now trying to commercialise the plans, compared with the new plan who subvert the lithium ion battery, these plans are more likely to end soon.
