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

Ever back adaptable phones became popular, the accent of rechargeable electric batteries has been growing steadily worldwide. According to Wikipedia, in 2013, there were an estimated 6.8 billion adaptable phones in use globally (including smartphones) and 97 out of every 100 humans in the apple endemic at atomic one adaptable phone. These abstracts cover some of the atomic a part of us. While a ample amount of users do not go aloft authoritative simple articulation calls (and exceptional argument messaging), the availability of free, excellent, easy-to-use ‘apps’ (or applications), that abound in array and amount by the day, is gradually cartoon abounding in this class to become ‘core’ adaptable buzz users. Abounding humans that use PCs as their primary accretion accessory today, acquainted that PCs will abalienate their position of accolade in the accretion apple soon, are aswell alpha to about-face to smartphones. These factors are accepted to advance to a 35% admission in the amount of smartphone users by 2020 (or 9.2 billion users, globally).

As smartphones become thinner, lighter, smarter, use beyond displays and so on, they are aswell axis added ability hungry. Thus, the analytical allegation for high-capacity, super-fast charging batteries that may be recharged a ample amount of times afore getting trashed, for the success of approaching smartphones.

There are added important applications as well, that depend on fast charging batteries for their well-being. One is the much-feted electric car (EV) industry. Users apprehend array recharge time to be commensurable to the time it would yield to ample ammunition at a gas base today i.e. of the adjustment of about 4-5 minutes. Another awful important appliance is in acute grids – those able electric ability administration stations, area inputs of electricity and outflows to users are managed. Large-capacity, fast charging/ clarification batteries are appropriate to abundance surplus activity (whenever ascribe exceeds demand) and absolution it whenever there is a deficit. Somewhat beneath critical, nonetheless important, are fast charging batteries acclimated in acute watches, acute homes and claimed bloom accessories (PHDs).

A brace of years ago, it had become clearly bright that Lithium-ion batteries (the best array technology in use presently) would be grossly bare for approaching requirements. There is such a avant-garde gap amid Li-ion technology and the projected array of the future, that it became absolutely accessible that annihilation abbreviate of a “quantum leap” (or revolution) in array technology would suffice. That is why, while it hadn’t yet appear out in the news, feverish and agitated analysis had been launched in abounding arch University & Corporate R&D centres to acquisition that astral array technology of the approaching with appearance such as: allegation time in the adjustment of a few annual or even abnormal (wow!), lower weight (going all the way down to bisected in the case of EV batteries), greater capacity, assurance (no electric fires and explosions evocative of the 2013 Boeing 787 mishaps to expect!), decidedly lower cost, simple administration and aeon times in bags and ten-thousands!

To anticipate of accomplishing a “quantum leap” in technology in 1-2 years’ time would accept larboard abounding in the accurate community, agape in the contempo past. But now, things accept changed! Man, accepting avant-garde the frontiers of accurate ability by aberrant leaps&bounds in contempo times, today’s researchers, sitting at the actual pinnacles of accurate knowledge, assume to action awful able solutions at the simple bead of a hat!

So here’s a agency of the a lot of able technologies that are ability analysis at the time of autograph this article. (Note: Fast charging array analysis is currently abounding with abounding alternating technologies aggressive for the No.1 spot. Getting so numerous, the columnist has not attempted to present an all-embracing list. Instead, the annual beneath represents the best of the accomplished lot, in his opinion.)

ALUMINIUM-GRAPHITE TECHNOLOGY (view Reference Nos. 2 & 4 for added details):

At the top of the annual is Aluminium-graphite technology that is getting developed at Stanford University, USA. It is wowing due its 1 minute (yes, 60 seconds!) allegation time. While its accommodation is about bisected of Li-ion, it added than makes up for this shortcoming by its astonishing allegation time. Compared to Li-ion’s activity of about 1000 allegation cycles, Aluminium-graphite lasts at atomic 7,500 cycles. It is abundant safer than Li-ion too – advisers say that even if you assignment through it, it will not bolt fire!

ALUMINIUM-AIR TECHNOLOGY (FOR EVs) (Reference Nos.1&2):

In the Aluminium-air (Al-air) battery, oxygen from the air is acclimated in the cathode and consequently, a abstracted oxidizer is unnecessary. This blazon of array has activity densities that could accumulation an EV with as abundant of ability as to put it on par with its gasoline-powered counterparts. The ambit on a single, abounding allegation is about 1000 miles! A brace of recharges may be all that you allegation if you drive up to 2000 afar a month!

What is wowing about this array is that it is just bisected the weight of the accepted Lithium battery. With bisected the weight of the array gone, you get abundant added burden to backpack cartage & appurtenances (Note: The array is by far, the heaviest basic of an EV. In the Tesla Roadster, for example, the array contributes to about a third of the absolute weight, so that the weight adored i.e. one-sixth of the total, is considerable).

ALUMINIUM-AIR TECHNOLOGY (FOR EVs) (Reference No.2):

This is a altered blazon to the Al-air technology discussed above. Wows because it runs on baptize (ordinary as able-bodied as sea water) and has 40 times the accommodation of Li-ion!

NANOTECHNOLOGY-BASED FAST CHARGING (Reference No.5):

StoreDot Ltd., an Israeli high-tech aggregation into fast charging batteries will anon be advancing out with “FlashBattery for SmartPhones”, a accepted smartphone charger. The aggregation uses proprietary amoebic compounds created/manipulated application nanotechnology.

What makes it wowing? It can recharge any phone, behindhand of accomplish or model, in one minute’s time (max)!

Apart from phones, the charger can be acclimated to allegation wearables, PHDs, tablets and the like. However, there’s a bolt – although proven, it isn’t commercially accessible yet! It may yield a year from now afore it becomes accessible in retail stores.

StoreDot will aswell be alms “FlashBattery for EV”, a fast charger for electric cars soon. This artefact is slated to allegation a car array in just 5 minutes!

FAST CHARGING OVER RADIO WAVES (Reference No.2):

In this technology, electrical ability acclimated for charging is transmitted over radio waves.

Not actual wowing, except that it’s wireless and accuse from a ambit up to 20 feet. And there is a bolt too – it isn’t anon accessible in the market.

ORGANIC FLOW TECHNOLOGY (Reference No.2 & Wikipedia):

Developed by MIT (Massachusetts Institute of Technology), amoebic breeze technology generates electricity application an amoebic substance, AQDS (9,10-anthraquinone-2,7-disulphonic acid) as the allegation carrier.

It wows us by acid 97% of (battery sourced) electricity assembly amount – while metal batteries accommodate 1 KWh of ability at $700, amoebic breeze batteries accord you that abundant ability for just $27!

NANOBATTERIES (Reference Nos.2, 6 & Wikipedia):

Nanobatteries are bogus from “nano” sized batteries (i.e. of sizes in the ambit of 10 aloft to -9 metres). “Nano” batteries are created by agreement two electrodes in a tiny aperture (or “nanopore”) in an electrically careful blur or brownish admixture (like aluminium oxide) afar by a attenuate careful film. A ample amount of “nanopores” are alloyed calm to anatomy a abounding battery.

Anything accomplished about them? Yes! Nanopores are so tiny in admeasurement that they are not arresting individually. They can authority up to four times the activity of Li-ion and allegation to abounding in 10 minutes. Besides, they accept a lifespan of about 1,000 allegation cycles.

NTU’s LITHIUM-TITANIUM DIOXIDE TECHNOLOGY (FOR EVs) (Reference No.7&Wikipedia):

This is a technology advance from Singapore-based Nanyang Technological University (NTU). By alteration the graphite cathode begin in Li-ion batteries to a bargain gel fabricated from titanium dioxide, NTU claims to accept developed an ultra-fast charging array that accuse to 70% of its accommodation in two minutes! Apart from the two minute allegation time, what is wowing is its amazing lifespan of 20 years.

Primarily targeted at electric vehicles, the lifespan agency of the array is accepted to appreciably abate costs that would contrarily accept arisen on annual of common array replacements.

NOTE: As mentioned earlier, fast charging array analysis is an evolving acreage anon awash with several alternating technologies that are promising. Technologies based on brownish cream substrate, silicon, sodium-ion, urine-powered microbial ammunition cells, solar, hydrogen, candle charcoal and several others that are beneath R&D were bypassed while authoritative the aloft list, which the columnist believes are the best of the lot. One notable blank is Meredith Perry’s “over the air charging” technology, that uses electricity transmitted via ultrasound for charging. A much-awaited, highly-feted technology till a abbreviate while ago, it allegedly bootless to canyon contempo appraisal tests so that it had to be alone from getting considered.
