Few are currently holders of smart accessories such as smart watch or bracelet for example. But we want it or not, the industry is determined to have these devices on the market. To fail to do so, however, we must first solve one of their biggest problems – power. The solution is clear – creation and mass production of flexible batteries.

Namely power supplies are one of the reasons for dissatisfaction with portable accessories. The batteries of these devices difficult withstand more than a few hours, loaded slowly and virtually negate their effective use, as one had to constantly have one mind, and to keep the energy supply. To top batteries are bulky and rigid, which severely limits the ability to create an attractive and compact design of the devices. Creating flexible batteries provide much more serious and complex challenge than expected. However, there are already quite developments in the field, some of them are quite promising.

To print out battery

Startup Imprint Energy, based in California, for example, developed a thin zinc-polymer battery that can be produced by 3D printers. Traditionally used lithium batteries. It is too toxic, necessary protective layers around it that actually make batteries bulky. Zinc, however, is not so scary and it is also more stable. The company has established and solid polymer electrolyte, which further improves the properties of zinc and battery as a whole. Print batteries are very thin and can be bent without damage to their performance, and can be produced in very tiny amounts. At the same time can save more energy in a smaller area compared to conventional lithium batteries.

A serious disadvantage is that they can be recharged, at least at this stage. According to co-founder Brooks Kinsayd However, this is not a problem. This type of batteries are very easy and cheap to produce, making them suitable for single use even for handheld devices. To online magazine Technology Review Kinsayd says the batteries can be used in clothing and “strange body parts like eyes.” His company developed and project American army to create a battery of sensors to monitor health indicators to the soldiers. Purpose of Imprint Energy are mostly unpretentious devices, sensors, medical equipment.

Non-stop, non-stop

Scientists from the University “Clarkson” in New York did work on another interesting project. According to them, the residual fiber from industrial hemp can be converted into highly efficient devices for energy storage. Currently, after the production of clothing and other goods from industrial hemp fiber that simply disposed says project manager David Mitlin, quoted by the BBC. However, they may become supercapacitors by transforming them into graphene electrodes. This wonder material is known for its many properties. The problem is that it is too expensive in its original form. So scientists are experimenting with bio as peat moss, eggs and even banana peels to synthesize it in another way. “You can do very interesting things with bio. Almost discovered the secret sauce, so to speak,” said Mitlin.

He cites the transformation of a banana peel in thick cubes carbon that scientists call psevdografit. In this form it can be used in the sodium-ion batteries. Fiber from industrial hemp it may be “almost cooked in a pan with high pressure.” This removes hemicellulose and lignin, leaving only carbon nanosloveve who do scientists call psevdografen. They added electrolyte supercapacitors becomes fully operational battery with a capacity of 20 kilowatts per kilogram, which is effective even at zero degrees Celsius. Charging time is only six seconds. The price does between 500 and 1000 dollars per ton. Scientists have already started and the company Alta Supercaps, which will try to launch the development of the market in the very near future.

Doubling stock

The aforementioned projects look very promising, but still far from the market. The company Applied Materials has developed a new process for creating so-called. solid-state batteries that can store twice as much energy than equivalent sized lithium-ion Bank. This type of batteries have existed for some time, but were also very expensive to produce, making them pointless for general use. Applied Materials, which is one of the biggest companies manufacturing equipment for the semiconductor industry and displays, however, found an easier way and already used in the manufacture of prototype “solid” batteries.

Their advantage over lithium-ion alternatives that can be produced in a variety of shapes and – contrary to its name – also can be bent, though not quite as paper. The absence of liquid electrolyte makes them more secure. Unfortunately, the company did not specify how long can this type rechargeable batteries. We are currently working to improve the conductivity of the solid electrolyte can be used for devices requiring more power, as the conductivity at the time it is not optimal. But now there are solutions for that.
