    Sunil,

    basically,all these technologies are far way from becoming reality as they are in nascent stage and needs much devlopment and practical feasibility tests.

    One is a temporary sticker,which when sticked onto our body will generate electricity and then it can be used to charge our device.Another one is preventing or lowing down the rate of passage of electrons which occurs during battery usage.

      Thank you. Did you recently read about blogs mentioning college student creating a revolutionary technology , like charging within seconds and even demo? and similar tech recently lot , mentioning new discoveries and Coffee store in US allowing wireless battery charging to coffee drinkers. Can you please mention any likely tech implementing or kind of patency accepted?

      There are many breakthroughs we come to see in this field.But in order to become it practical,a lot of work has to be done.I've seen the articles you mentioned about it.As far as I've seen,none of the emerging tech has not been certified for consumer devices.

    Not stricly batteries, supercapacitors nevertheless can be used as batteries in some areas, and you may enjoy this little story: http://www.worldatlas.com/aatlas/ctycodes.htm.

      Thank you. Please tell , is any tech approved by Governing Institute for international implementation? or likely to gain approval to be allowed in mobile phones? If yes , please weblink

    Hey Sunil, that's an interesting question.

    Right now the technologies that are beginning to allow for quicker charging times are actually the batteries themselves. Although I'm aware of other faster charging methods (some are firmware based and inside of the phone itself, such as "quick charge") such as nano-wire batteries.

    Nanowire batteries are a revolutionary new technology that are ALREADY out in phones! Unfortunately, manufacturers refuse to brand them as such, and they often make the phones slimmer, rather than boosting mAh.

    But anyway, nanowire batteries allow for both faster charging AND longer lasting (more durable) lithium-ion batteries. As for 2014, there's several variations on the technology, including silicon-anode, germanium-anode and silicon-platelet technology. They offer theoretical capacities of up to 10x more charge and substantially faster charge times.

      Thanks for interesting reply. Please tell , a) are nanowire batteries been implemented in which models? Can you mention any particular model name of phone

      b) Are such batteries affordable ( within same or slightly higher range than current batteries )

      I've actually written nanowire companies about labeling (they won't respond on this question). The batteries themselves are very affordable, since all it requires is changing the anode on a regular battery. In fact, they are cheaper to produce than regular lithium-ion batteries.

      Unfortunately, there's a lot of reasons why they won't brand them and many manufacturers won't adopt them anytime soon. Many companies prefer incremental upgrades, rather than revolutionary ones. Revolutionary advancements in battery technology encourage consumers to wait things out, in the hopes that better technologies show up in the future. Incremental advancements tend to push consumers to buy immediately, since the next generation is never much better than the current one.

      The nanowire batteries last a lot, lot longer than current technologies (after a break-in period, they lose around .01% of total capacity, per complete charge cycle). However, there's a lot of things that may prevent the nanowire batteries from getting more attention. Mainly, lawsuits may end up deciding whether those batteries become more popular.

      Thanks. I guess , it is a patency war

      I did not want to say that directly, but - yes - it looks like patents may determine whether nanowire batteries ever get adopted. It would make electric cars much cheaper and more feasible - there's a lot of companies that wouldn't like to see that happen. :-(

      Thanks. Please tell , is patency determined fully on merits of new technology , or there is partiality / discrimination?

      The American patent system suffers from a number of flaws. Most large businesses carry portfolios of "protective" patents, which allow them to keep competitors from introducing market-changing technologies. On one hand, it provides for more stable markets. On the other hand, it holds all of us back.

      I don't know if patents are holding back nanowire technology, but the legal system has crushed a lot of other inventions that would have changed the way we live. My favorite is the oral rinse that may have cured tooth decay:

      I don't know if it would have worked, but the patent system prevented it from being sold. In the scientific studies conducted on the oral rinse, though, it did work. It even entered a limited human testing phase (the American regulators have not publicly commented on anything pertaining to the Oragenics oral rinse).

      Thank you with respects for delving deep into this question! Lot of corruption and miseries due to self centeredness! On a broader note , the authorized text books of Life say that this material planet is place full of miseries and temporary. There is anxiety and danger at every step! http://www.twitter.com/Goodysunny
