Amazing battery technology of the near future
While smartphones, electric cars and other digital devices become more advanced, they are limited by energy. Charge a modern phone lasts only 1-2 days, and the reason for this lies in the very slow development of battery technology over the last decade. Therefore, the teaching and the business decided to enhance its work in this area and begin to provide impressive prototypes. In the material we have reviewed the most interesting and promising battery technology of the future.
Full recovery of battery in 30 seconds
Cartap StoreDot, which originated at the Department of nanotechnology at tel Aviv University have developed a device that can fully charge your smartphone in 60 seconds. The battery consists of flame-retardant organic compounds (peptides), covered with a multilayer protective structure that prevents strain and heat.
The company also plans to create a drive for electric vehicles, which is restored in five minutes and allows you to drive 500 km. Commercial production was scheduled to begin by early 2018, but the date was postponed. Despite the delay, the product has become very popular.
Researchers from the UK has created a phone that could be recharged from the surrounding sound. The principle of its operation is based on piezo effect. This was created nanogenerators that picks up ambient noise, and convert it into electric current. In fact, the phone can be powered from the sound that is always present around us.
The British team has added zinc oxide in a special chemical mixture and covered the device. As a result, the entire surface was formed of tiny nanorods. They are so sensitive that bend from the pressure of sound waves. These oscillations are collected by the nanogenerators, which convert it into electric current, powerful enough to restore the battery.
The rods respond to the human voice, so in the process of communication, users can add credit to your charge.
Sand can increase energy 3 times
In an alternative type of lithium-ion battery uses sand instead of graphite. Scientists at the University of California riverside initially planned to use nanoscale silicon, but it degraded too quickly and hard to produce in large quantities. So they decided to use sand that can be easily cleaned, put in powder and then moistened with salt and magnesium before heating to remove oxygen resulting in pure silicon.
This has resulted in a threefold increase in the intensity of a galvanic cell, and its production is inexpensive and environmentally friendly. Additionally it has a porous three-dimensional structure, which increases the service life and efficiency.
Charging from the movements of the person
Researchers from the University of Surrey to develop a way to use our clothes as a source of energy. Battery Triboelectric Nanogenerators (TENG) that converts the traffic into accumulated charge. Stored electricity can then be used to power mobile phones or other gadgets.
This technology can be applied not only to clothing, but also integrated into the pavement or the tires of the car. Energy arising from pedestrians or vehicle, may be collected and sent to power street lamps or appliances cars.
The replenishment of charge from the air
The concept was developed by astrobiologist Meredith Perry, uBeam founder of the company. It proposes to use ultrasound for charging mobile devices. Electricity is converted into directed sound waves, inaudible to people and animals, getting the gadget is converted back into energy.
The technology allows to transfer the charge literally in the air with plate thickness of 5 mm. Small transmitters can be attached to walls and even to be part of the decor of the room, radiating at the same energy for smartphones and laptops. To convert energy gadgets just need a special fine receiver.
Eternal batteries of nanowires
Another achievement is to extend the operation to such a level that users never had to worry about replacing the battery. Researchers from the University of California Irvine have developed nanodialogue batteries that can withstand 200 thousand cycles of charges are not showing any signs of deterioration in performance.
Tiny gold threads that are thousands of times thinner than a human hair, have excellent conductivity and large surface area, which bodes well for the performance of future drives. Before the problem was their rapid destruction in the charge, but the scientists were able to prevent this by coating the nanowires with a shell of manganese dioxide and helium electrolyte.
High-performance graphene batteries
Graphene batteries can be one of the most excellent. The company’s product Grabat generates enough energy to the electric car could travel up to 750 km on a single charge. The developers claim that they can fully recover in just a few minutes, and be charged and discharged up to 33 times faster than Li-ion.
The category is also crucial for such devices as cars, to drive fast which require a lot of energy. The company already has products for cars, unmanned aerial vehicles, bikes and even houses.
Compact and cheap foam batteries
In Prieto, the company believes that the future of 3D-printed power sources with a basis of copper foam. These drives will not only be safer thanks to the absence of flammable electrolytes, but will last longer, faster to charge. Their density is five times higher, and the size and the cost is much lower than that of current batteries.
7 times higher capacity sodium-ion batteries
Scientists from Japan are working on new types of batteries that do not need lithium. They will use sodium, one of the most common materials on the planet, and seven times more efficient than conventional batteries. Studies of sodium-ion energy sources are continuing with the eighties trying to find a cheaper alternative to lithium rare. Using salt, the sixth most abundant element on the planet, the battery can be done much cheaper. It is expected that commercial production will begin in the next five to ten years.
Flexible paper battery
Development Jenax J. Flex was designed for use in flexible gadgets. Paper storage can be folded and waterproof, allowing you to integrate it into clothing and wearable items. The product is already developed and tested for safety, it can also bend for 200 thousand times without loss of performance.
A team of scientists Binghamton University has developed a similar paper disposable battery that uses bacteria as an energy source, and to activate the desired normal water.
Charger hydrogen fuel
Now available portable battery charger for hydrogen fuel cell Upp. It uses hydrogen to power the phone and is completely harmless to the environment.
One hydrogen element will provide five full charges of a smartphone (capacity 25 watts per each cell). The only byproduct is water vapor. Upp can charge most USB devices with output 5 V, 5 W, 1000 mA.
No less amazing are the materials from which may consist of digital devices of the future.
