According to Shenzhen Viwipow Electronics Co.,Ltd.nding, the battery has been one of the bottlenecks which restrict the development of intelligent mobile phone. And, in addition to the intelligent mobile phone, solar power, wind farms also by battery technology limited. These places need cheap,durable and high power battery to store electric energy.

"The battery became almost all electrical equipment 'weakness'." American chemist at the Colorado State University Amy Prieto said.

To this end, she set up a specialized development of electrical energy storage equipment company.The company will launch a than the existing lithium-ion batteries safer, cheaper, faster charging andmore environmentally model -- foamed copper battery friendly.

Currently on the market of the battery has high price, easy to heat, short service life and the manufacturing process will pollute the environment and a series of shortcomings. But in the AmyPrieto view, which has two disadvantages: the most important low energy density and low power density.

She explained, the former refers to the traditional battery based on the existing volume, it is difficult to guarantee the intelligent mobile phone has more than two days duration; the latter refers to thebattery charging for hours, not minutes.

The Amy Prieto team through the redesign of a series of cell components, such as copperantimonide negative electrode and polymer electrolyte materials to solve the problem. Among them,the most important is designed, the team used a metal foam -- foamed copper as cathode of the battery (the collector current will be responsible for battery active material generated together toform the current foreign output larger parts).

Amy Prieto said, compared with the planar electrode, foaming copper material due to its largesurface area, energy density and power density can significantly improve the battery.

"And this device is also relatively easy to manufacture." Amy Prieto introduction, their first in thefoamed copper cathode material by plating on copper antimonide material. Then, put the negativeto a specific solution, make solid electrolyte in the electrochemical polymerization reaction under the action of the above, deposited onto the anode. Finally, the researchers used a piece of aluminummesh as the battery anode, battery production.

Amy Prieto estimates the manufacturing cost of the battery is only half the cost of traditional lithium ion battery. At the same time, on the premise of having the same power, the volume of only 2/3 of traditional battery, and the charging time is shortened to five to 1/10, life expectancy has increased by ten times.

More importantly, this new type of battery has the characteristics of more safety and environmental protection. First of all, the risk of spontaneous combustion of solid electrolyte is much smaller than in the liquid electrolyte. In addition, in the whole manufacturing process, the team chose to water instead of other chemical substances as basic reactant. "I didn't think it was possible, but for now at least, the effect of water well." Amy Prieto said.

At present, the team has been successful in a copper manufacturing a two-dimensional model of the battery, is carrying out three-dimensional cell model test. "A year later, the battery prototype that appear, at the appointed time, we will invite third parties to test." Amy Prieto said, "then, we will also carry out the small scale market test."

Shenzhen Viwipow Electronics Co.,Ltd will keep eye on these high tech in futher.
