At present, the common lithium-ion batteries are applied technology, but the technology has almost reached its "limit": the researchers said, the lithium-ion technology is currently based on a maximum of 30% increase.
Wall Street analysts bullish on scientific and technological breakthroughs in the field of battery.Perhaps in the near future, we are cars, houses, and so will the use of mobile phones to inexpensive, and efficient energy.
Now we are to meet the breakthrough in battery technology
, they are able to make our life a few days smartphones, allowing a single full charge electric vehicles run more than 500 kilometers, enabling our house for energy storage can be used a few days. Future, this six new battery technology will change the way we live or:
1. lithium sulfur battery
Lithium sulfide (lithium-sulfur) is probably the closest maturity, the cheapest and easiest to implement next-generation battery technology. Energy density lithium sulfide is about five times the current lithium-ion batteries, and materials needed for the production of relatively cheap price of the former. Fast "aging" is a major problem faced by lithium sulfide. However, researchers have been able to obtain lithium sulfide over 2000 times the charge cycle, you can follow the best currently available lithium-ion batteries "comparable."
However, lithium sulfide biggest advantage is that it can be very small, very light battery pack to store such a high energy density, this "body" exactly in line with the current smartphone slim design.
2. The porous silicon lithium-ion battery
Researchers at the University of Southern California, the use of micro-porous silicon sphere as the positive electrode of the battery, at lower cost from fast lithium ion "release", and as such, it is a smart phone conventional energy storage battery is more than three times, charging just 10 minutes. Once the porous silicon lithium-ion battery charge cycle can raise up, this technology is very suitable for application in the battery field. We expect that in the next year will see the first of these batteries.
3. Magnesium Battery
In addition to the lithium-ion battery, the battery is also good prospects for magnesium.Magnesium battery energy density is 8-12 times that of lithium-ion battery charge and discharge efficiency is five times the latter, this is because the magnesium ions in the electrolytic solution carries a double positive charge, thus improves overall energy density, and the electrical energy can be stored in any given size of the battery pack. Although you want to achieve the magnesium battery applications, there are some "obstacles" need to be cleared, but a large number of researchers are now engaged in the study of this technology.
The lithium-air battery
IBM is currently joint researchers, government agencies and industry experts in laboratory called "Project 500" project to develop lithium-air batteries. It is reported that this battery can give electric cars can be achieved with a traditional storage tank of the same road mileage. Moreover, lithium-air batteries can also be a good application in the mobile space. This battery works is simple: when the battery is "discharged" from the oxygen in the air will react with lithium ions and a carbon matrix generation lithium peroxide. When the battery is charging, the oxygen will return to the atmosphere, to return to the lithium-ion battery anode. Currently, this technology is still a very distant future projects, but recent research in the field has allowed us to see its feasibility.
5. inspiration from nature: stone turtle and snail shells teeth peptide
Teeth are the hardest stone turtle organic substances found in humans so far, California researchers use them in very small cost synthesis of a nano-crystal, this material can significantly enhance the battery charge rate.
Another study of snail shells isolated peptides, it is a biological molecule, capable of generating a lithium nickel manganese oxide, this material can be used to serve as a high-performance battery anode.
6. flexible, folding, stackable battery
Besides increasing the energy density and number of charge cycles, the new battery materials can also be used to optimize the structure of the mobile battery, so that it can adapt to the smartphone designs. Currently, Samsung and LG has announced its stackable or foldable battery pack, and they have done the production preparation. Now, this type of battery applications to real devices only a matter of time.
