Fast Charging Battery Research: Hot, Super High-Tech & Wowing!

Since mobile phones have become popular, the importance of rechargeable electric batteries has grown steadily around the world. According to Wikipedia, in 2013, around 6.8 billion cell phones were in use worldwide (including smartphones) and 97 out of every 100 people in the world owned at least one mobile phone. These numbers include some of the poorest among us. While a large number of users don’t just make more voice calls (and infrequent text messages), the availability of free, great, and easy-to-use “ apps ” (or apps). use, the variety and number of which is increasing day by day, is gradually attracting many members of this category to become “main” mobile phone users. Many people who use PCs as their primary computing device today, realizing that PCs will soon abandon their preeminent position in the computing world, are also starting to make the switch to smartphones. These factors are expected to lead to a 35% increase in the number of smartphone users by 2020 (or 9.2 billion users worldwide).

As smartphones get thinner, lighter, smarter, use bigger screens, etc., they also become more power hungry. Thus, the critical need for high-capacity, ultra-fast charging batteries that can be recharged a large number of times before being thrown away, for the success of future smartphones.

There are also other important applications, which depend on fast charging of batteries for their well-being. One is the highly regarded electric vehicle (EV) industry. Users expect the battery recharge time to be comparable to the time it would take to refuel at a gas station today – in the order of ‘about 4 to 5 minutes. Another very important application is smart grids – those smart electric power management stations, where electricity inputs and outflows to users are managed. Large capacity, fast charging / discharging batteries are needed to store excess energy (whenever input exceeds demand) and release it whenever there is a deficit. The fast-charging batteries used in smartwatches, smart homes, and personal health devices (PHDs) are a little less critical, but important nonetheless.

A few years ago, it had become undeniably clear that lithium-ion batteries (the best battery technology currently in use) would be grossly inadequate for future needs. There is such a gap between Li-ion technology and the projected battery of the future, that it has become quite obvious that nothing less than a “quantum leap” (or revolution) in battery technology will would suffice. This is why, while it has not yet made the headlines yet, a feverish and frantic search has been launched in many leading academic and corporate research and development centers to find this exalted battery technology of the future. with features such as: charging time in the order of a few minutes or even a few seconds (wow!), reduced weight (up to half in the case of EV batteries), greater capacity, safety (no fires electrics and explosions reminiscent of the 2013 Boeing 787 misadventures to be expected!), significantly lower cost, easy handling and cycle times in the thousands and tens of thousands!

Thinking of achieving a “quantum leap” in technology within one to two years would have left many members of the scientific community stunned in the recent past. But now things have changed! Man, having pushed back the frontiers of scientific knowledge by unprecedented leaps in recent times, today’s researchers, sitting at the height of scientific knowledge, seem to offer very promising solutions in the blink of an eye. eye!

So here is a list of the most promising technologies that are being researched at the time of writing this article. (Note: Fast-charge battery research is currently inundated with many alternative technologies competing for the # 1 spot. Being so numerous, the author has not attempted to present an exhaustive list. Instead, the list below represents the best of the whole, in his opinion.)

ALUMINUM-GRAPHITE TECHNOLOGY (see references 2 and 4 for more details):

At the top of the list is aluminum-graphite technology which is being developed at Stanford University in the United States. It is amazing because of its 1 minute (yes, 60 seconds!) Charge time. Although its capacity is about half that of Li-ion, it more than makes up for this shortcoming with its incredible charging time. Compared to Li-ion’s lifespan of around 1,000 charge cycles, aluminum graphite lasts at least 7,500 cycles. It’s also much safer than Li-ion – researchers say even if you pierce it, it won’t catch fire!

ALUMINUM-AIR TECHNOLOGY (FOR VE) (references n ° 1 and 2):

In the aluminum-air (Al-air) battery, oxygen from the air is used in the cathode and therefore a separate oxidizer is not required. This type of battery has energy densities that could provide an electric vehicle with as much power as putting it on par with its gasoline-powered counterparts. The range on a single full charge is approximately 1000 miles! A few recharges may be enough if you drive up to 2000 miles per month!

What’s impressive about this battery is that it only weighs half the weight of the current lithium battery. With half the weight of the battery, you get a lot more payload for carrying passengers and cargo (Note: the battery is by far the heaviest component in an electric vehicle. In the Tesla Roadster, for example, the battery contributes about a third of the total weight, so the weight saved either a sixth of the total is considerable).


This is a different type from the Al-air technology described above. Wow because it works on water (ordinary as well as sea water) and has 40 times the capacity of Li-ion!


StoreDot Ltd., a high-tech Israeli company specializing in fast-charging batteries, will soon release “FlashBattery for SmartPhones”, a universal smartphone charger. The company uses proprietary organic compounds created / manipulated using nanotechnology.

What makes it amazing? It can charge any phone, regardless of brand or model, in one minute (max)!

Besides phones, the charger can be used to charge portable devices, PHDs, tablets, etc. However, there is a catch – although proven, it is not yet commercially available! It may take a year from now before it becomes available in retail stores.

StoreDot will also offer “FlashBattery for EV”, a fast charger for electric cars. This product is designed to charge a car battery in just five minutes!


In this technology, the electrical energy used for charging is transmitted by radio waves.

Not very impressive, except it’s wireless and charges up to 20 feet away. And there is also a catch – it is not immediately available in the market.

ORGANIC FLOW TECHNOLOGY (reference n ° 2 and Wikipedia):

Developed by MIT (Massachusetts Institute of Technology), organic flow technology generates electricity using an organic substance, AQDS (9,10-anthraquinone-2,7-disulfonic acid) as a charge carrier.

It wows us by reducing electricity production costs (from batteries) by 97% – while metal batteries provide 1 KWh of energy at $ 700, organic flow batteries give you so much energy for just $ 27!

NANOBATTERIES (references n ° 2, 6 and Wikipedia):

Nanobatteries are made from “nano” size batteries (that is, sizes between 10 and -9 meters). “Nano” batteries are created by placing two electrodes in a small hole (or “nanopore”) in an electrically insulating membrane or a metallic compound (such as aluminum oxide) separated by a thin insulating film. A large number of “nanopores” are fused together to form a full battery.

Something superlative about them? Yes! Nanopores are so small that they cannot be seen individually. They can hold up to four times the energy of Li-ion and fully recharge in 10 minutes. In addition, they have a lifespan of around 1000 charge cycles.


This is a technological breakthrough from Singapore-based Nanyang Technological University (NTU). By replacing the graphite cathode of Li-ion batteries with a cheap gel based on titanium dioxide, NTU claims to have developed an ultra-fast charging battery that recharges to 70% of its capacity in two minutes! Besides the two-minute charge time, what’s impressive is its extraordinary 20-year lifespan.

Primarily targeted at electric vehicles, the battery life factor is expected to significantly reduce costs that otherwise would have occurred from frequent battery replacements.

CLASSROOM: As mentioned earlier, fast-charging battery research is an evolving field that is currently teeming with several promising alternative technologies. Technologies based on metallic foam substrate, silicon, sodium-ion, microbial fuel cells powered by urine, solar, hydrogen, candle soot and several others that are in the process of R&D have been bypassed when compiling the above list, which the author claims is the best plot. One notable omission is Meredith Perry’s “over the air charge” technology, which uses ultrasonically transmitted electricity to charge. A much anticipated and highly regarded technology not long ago, it apparently did not pass recent benchmarks, so it had to be scrapped.
