Solid State Batteries “Could” last a Lifetime

Among the many annoyances of a tech lovers life which includes, overheating, constant patching, hacking and dropped connections, there is the term battery or lack of considering your average smartphone is dead by the end of each day. Don’t get me started on your run of the mill double A battery, it was fine for a Gameboy, until you had to unreel a long wire with a plug on the end to continue playing, but not for today’s hi-tech toys.

Hopefully, an evolution is on the horizon after researchers at MIT and Samsung have developed a new approach to one of the three basic components of batteries, which in this case is the electrolyte. The premise involves developing a solid electrolyte instead of the current liquid used in today’s most common rechargeables. Current batteries use a liquid organic solvent whose function is to transport charged particles from one of a battery’s two electrodes to the other during charging and discharging, this process has been responsible for the overheating and fires which have caused high-profile disruption.

Another advantage of a solid state electrolyte is the ability to limit degradation to near 0; therefore such batteries could last for “hundreds of thousands of cycles.” Researchers also state these batteries provide a 20 to 30 percent improvement in power density. This means the amount of power that can be stored in a given amount of space can be increased.

By reducing these factors, researchers are hopeful this technique will improve efficiency and waste of the common battery, which in turn will benefit consumers. On a side note, it will be interesting to note how you would put this into practice with the aim of analysing if these batteries would really last for hundreds of thousands of cycles. Indefinite lifetimes in theory, let’s see what a Galaxy S6 makes of that.

Thank you MIT for providing us with this information

    again stuff on batteries, yet nothing so far has gone mainstream

      Most of this stuff takes a while to develop for mass production, you can’t just come up with something and expect it to be on the shelves the next week.

        Not to mention the companies producing the extremely fast charging have stated that it will increase smartphone costs by at least $100-$150. That’s not something that phone manufacturers are going to be jumping on anyway.

          Well… apple would. Hell… they already charge $950 for the iphone 6+ (a phone with a 5.5″ 1080p display….. I remember 2013). I will be getting the Moto X Pure. $399, 5.7″ 2560x1440p display (1.5mil more pixels). oh.. and it has a micro SD card slot. People love to pay for gadgets with half eaten pieces of fruit on them. And iphones really DO need better battery life lol

        there are articles like this that go waaaaay back. like 5 years or more.
        most battery inventions just don’t pan out, or perhaps (although quite unthinkable) battery coorperations buy the technology and never release it since it would make their sales go down.

          Yeah I know, it kind of reminds me of “the cure to cancer”, where we’ve been fairly close for quite some time, but at the same time, we’ve made strides in detecting and treating it.

          Although, wouldn’t battery corporations buy the technology for themselves in order to profit off of it? IMO the last thing we should start having are somewhat conspiratorial thoughts.

    • Weston Konik

      So you are upset that you are being told what will come in the future? LCD panel tech goes back to at least the early 70s, yet we only started seeing them being produced and become mainstream till the dawn of this century. Just because it isn’t on store shelves does not mean it shouldn’t be reported on or recognized.

    It is extremely important to have batteries that last forever, if we are going to have electric cars in the future, in every house. The last thing we need is mountains of bad car batteries.

    WOW! People should seriously stop “finding” new battery technology EVERY WEEK and actually put their heads together to DEVELOP these batteries – so that real people can [really] start using them.

    I know it’s hard and takes time, but it surely will be very faster if all the companies get together and start a “standard” for the actual development of these [ so called ] longer lasting batteries.
