The Future Of Battery Technology: From Super Capacitors To Wireless Charging In The Air

- Sep 28, 2017-

Electricity, no doubt the greatest discovery of mankind, has been unable to leave electricity.And in consumer electronics, any digital product is also reliant on batteries, and people expect battery life to be as long as possible, reducing the number of charges per day.

From nickel metal hydride battery to lithium batteries, lithium polymer batteries, cell phone and other digital products battery life may not be perfect, but also need to change the Angle to see, because the mobile phone has now is multimedia Internet terminals, rather than just a phone call.Of course, the battery and charging technologies need to evolve, so let's look at the most promising new battery and charging technologies.

Super capacitor


Supercapacitors may be the most promising next-generation battery technology.First, it can store energy in an electric field, not in a chemical reactant, which means it can withstand more charging and discharging cycles.

At present, many technology companies in the development of super capacitor, such as Skeleton Technologies, the product USES the technology of coupling hybrid supercapacitors, can make the battery has high energy density, high power and output characteristics, in a short span of 2-3 seconds can be full of electricity, and provide about 1 million times the charge cycle, battery capacity is 50% higher than current lithium batteries.

Solid-state batteries


Although the lithium ion battery has been around for a long time, it has the characteristics of high popularity and low cost, so it is not realistic to replace it completely.However, companies such as Toyota have started developing solid-state lithium-ion batteries, which are safer and faster than those of liquid lithium batteries.Toyota's solid-state batteries, which can be recharged in seven minutes, are also ideal for use on electric vehicles, which can dramatically shorten charging times.

In addition, solid-state batteries future forms include aluminum air battery, sand, etc., these technologies are the focus of the environmental protection, low cost and superior performance, perhaps one day will entirely replace liquid lithium battery.

A phone that doesn't need to be recharged


The phone doesn't need to be recharged, but it's also a viable option.Engineers at the university of Washington in the United States have designed a mobile phone that continuously absorbs solar energy through tiny solar panels that do not even require a built-in lithium battery.Of course, the current technology can only provide electricity for phones with very simple functions, and it will take time to actually apply them to smartphones.

The power of the environment

There are many ways to get electricity, even converting elements of the surrounding environment into energy.For example, sound, a technology that converts sound to electricity through a nanogenerator, provides a steady stream of electricity to the phone.Scientists at the Massachusetts institute of technology have found a way to absorb dew from the air and turn it into electricity.The world is wonderful, and as scientists get deeper, maybe a lot of the things that are not around us can provide energy.

Air wireless charging


The emergence of wireless charging technologies such as Qi has reduced the cumbersome operation of charging the equipment to a certain extent, and it is not necessary to find data lines, connections or very convenient.

Of course, this coil based wireless charging method still requires the device to touch the charging base, not really "wireless".

And the emergence of air wireless charging technology such as uBeam, can through microwave transmission energy, from a distance, of true air wireless charging experience, equipment charging, no longer need to contact more convenient.

With a bit of science fiction, the future may be like using WiFi and cellular networks to transmit electrical energy signals in the air.

Biomass power

Humans are creatures that generate energy in their own right, and that energy can actually be converted into electricity.

The Bill Gates foundation has now developed a technique for extracting electricity from human urine, known as "microbial fuel cells".

There is also a silicon gel structure that integrates nano-thin films, which can generate friction on the skin to generate electricity, which is very suitable as an energy source for wearables.
