new trends in lithium battery technology
in recent years, with the rapid development of mobiles electronic devices, more powerful processors, video cards, ultra clear and even flexible screens are impressive. unfortunately, the breakthrough in battery technology is slow, so far we still have to endure a day or so of endurance. although we have been concerned about the development of new material batteries, but in fact, the most likely breakthrough in the near future is still lithium battery technology. next, let's take a look at the development of the next generation of battery technology.
we are now basically inside mobiles electronic devices are used in lithium batteries or lithium ion battery, lithium battery using lithium metal or alloy from nonaqueous electrolyte battery anode materials, ni mh battery has had relatively higher capacity, better stability and can be repeated charge and discharge characteristics, after years of development has been quite mature. at present, almost all of the consumption level of lithium battery comprises an anode made of graphite. on the downside, often by fire and explosion of news reports, we already know, the lithium battery short circuit, overheat condition, very easy to control the explosion, which is why we advocate the user use the original battery, charger, data line, to prevent the lithium battery short circuit.
the improved form of lithium batteries is diverse, but the direction is basically established in terms of better safety, charging speed, flexibility, shape and performance. here are some of the new technologies that promise breakthroughs.
1. faster charge rates
nangyang : the r & d team at the university of technology has developed a new type of lithium-ion battery that is not the same as other technologies, not lifting capacity, but charging time. in just two minutes, you can quickly fill 70% of the power and charge more than 10000 times. the technology uses titanium dioxide instead of graphite as an anode material, while qualcomm corp also uses a better control chip to achieve a more stable charge effect. this technology is characterized by its low cost and great suitability for mobiles products and electronic automotive industry.
2. nonflammable components
first of all, the safety of lithium batteries is one of the most want to solve the problem, the scientists found a pfpe organic solvent is more stable, can reduce effect of crystallization on electrode, improve safety and prolong the service life of batteries. although the technology still takes time to test, it is expected that soon non flammable lithium batteries will be on the market.
3. flexible lithium battery
we are all looking forward to the emergence of fully flexible electronic devices, but even if the flexible screen has made little progress, but the battery is still a problem. lg recently demonstrated a fully curled oled screen, with screens, circuitry, and batteries flexible, which we see as the most flexible electronic device in science fiction movies.
in addition, a chinese taiwan company has recently announced the beginning of the production of flexible ceramic lithium polymerization battery, has a very safe features. although the battery capacity may not be ideal, but it is very suitable for wearable devices, is expected to launch in the market this year.
4. : lithium, sulfur and lithium air batteries
the other two promising new types of lithium batteries are lithium, sulfur and lithium air batteries. the former is characteristic does not require high volatile solvents, greatly reducing the fire hazard, even suffer a greater impact; the latter theoretically has higher energy density, suitable for electric cars and other products, but the challenge is to model the electrode and electrolyte. from now on, lithium sulfur battery has the advantages of large capacity, low cost and high security. it is likely to take the lead in the mainstream.
5. lithium anode
stanford university scientists recently published a paper found that ultra-thin carbon clusters can allow lithium metal as an anode, the amount of electricity raised is 10 times the current graphite anode. however, the current efficiency can only reach 96%, into the mass consumer electronics market will take time.
6. magnesium battery
magnesium is also a metal element that is expected to be used in the field of batteries. magnesium ions can carry two times the energy of lithium ions, while they have shorter charging time and stable performance. the magnesium battery has been commercially available a few years ago, so it is expected to be faster in the consumer world than any other new battery material.
7. super capacitor
ultracapacitor is a battery technology different from the traditional lithium structure. it can achieve large capacity and ultra high speed charging, but the main obstacle is the capacitor usually can not store energy. china's tsinghua university, university of texas, national university of singapore in the super capacitor storage battery r & d different materials, including carbon nanofluids, graphene and so on, but these technologies have high energy heavy, aggregate stability and other problems, it is difficult to short-term in the consumer market in popularity.
the new battery technology is still in the development stage, but it is certain that the improvement of lithium battery technology is expected to the first landing based on the market, we are expected to use lithium battery faster, more durable and safe in a few years. the super capacitor and battery, magnesium air battery, solar cell and so on completely different cell types, then take time to improve, if successful, electronic equipment, the next revolution will come to enjoy rapid online games is not a myth.
