Remember the energy floor tiles we recommended to Shanghai Disney? From a professional perspective, this is a new type of battery - flywheel battery (Intelligent Hardware Station Note: Flywheel battery is a new concept battery proposed in the 1990s. It breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage) .

There are more and more new types of batteries, which is also an urgent need to understand today's smart devices. Take a mobile phone as an example. If it runs out of power, it will be like a brick. To this end, scientific researchers and hardware manufacturers are working hard on battery materials and technology, hoping to discover better battery materials, and also hope to increase the battery capacity and improve battery life. Today, let’s take a look at these magical batteries.

Ultra-light photovoltaic cells

Everyone knows that the size of the battery limits the acceptable form factors of smartphones, computers, and wearable devices.

An ultra-lightweight photovoltaic cell has been developed that makes those so-called battery limitations nonsense. Because its characteristics are not only light, but light enough to put it on a bubble.

The MIT researchers say the core of making the battery lies in technology, not materials. They implement the battery, substrate and protective layer on the same process, so that they can be protected from dust intrusion.

A flexible polymer called polyparaxylene is used as the substrate and protective coating, while the main light-absorbing layer is made from an organic material called dibutyl phthalate. What’s more, the entire process is done under vacuum at room temperature without the use of any chemical solvents or harsh chemicals.

When everyone focuses on battery life, paying attention to the size of the battery is also a new expansion point.

This battery is very light and has a wide range of applications, such as being embedded in clothes or laptops, in space or high-altitude environments, and it can be used as a simple expansion of existing equipment.

Flexible solar cells

Traditional inorganic optoelectronic devices (ie, solar cells) are nothing new, but they must be processed into hard plate-like objects in order to absorb solar energy over a large area, which obviously limits daily applications. Flexible devices are lightweight and can be folded, rolled, and pasted on curved surfaces, such as automotive glass, roofs, clothes, etc.

If flexible solar cells become a reality, wearable devices will become even more perfect.

At present, scientists from my country, the United States and South Korea have developed similar batteries that can change their shape to suit different devices.

Professor Xiong Yujie's research group at the University of Science and Technology of my country designed a solar cell that can perform photoelectric conversion in the near-infrared region and is mechanically flexible based on the widely used semiconductor silicon material and the hot electron injection method of metal nanostructures.

Xiong Yujie's research group integrated silver nanosheets with near-infrared light absorption properties and silicon nanowires to construct two different photovoltaic devices. Under near-infrared illumination, hot electrons emerging from the silver nanosheets can be directly injected into the silicon semiconductor. , the photoelectric conversion efficiency in the near-infrared light region is increased by 59%.

This flexible battery can be installed on your skin to provide enough power for wearable devices at any time. The results are expected to be used in the development of intelligent temperature-controlled solar cells and wearable solar cells.

Hydrogen fuel cell

It is not uncommon for batteries to make a fuss about fuel. The hydrogen fuel cell that Xiaozhan is going to talk about can increase the battery life of the drone to 2 hours.

The British company Intelligent Energy has developed a hydrogen fuel-powered battery that allows a drone to fly continuously in the sky for 2 hours, and can replenish fuel immediately after landing to continue flying.

This drone's hydrogen fuel cell weighs only 1.6 kilograms when fully loaded with fuel, which is even lighter than lithium-ion batteries.

Currently, this hydrogen fuel cell has been installed on the DJI Matrice 100 drone and successfully tested. Intelligent Energy said the battery could be available as soon as the end of this year.

However, due to the particularity of this hydrogen fuel cell fuel, the battery's dangers have increased a lot. As long as the technical controls are strict enough, the risk factor can still be controlled.

Sucrose battery

First of all, a correction, this sucrose battery is not made from sucrose. Just ordinary sucrose in daily life can be used to generate electricity.

The research results of MIT scientists show that when sucrose is used to coat carbon nanotubes and the carbon nanotubes are ignited from one end, thermal energy waves (TpW) will appear to push the electrons in the tube forward, and then an electric current will appear.

All major reports say that this principle is very complicated! I guess the principles worked out by scientists are not something ordinary people like us can understand. Let’s talk about its uses~

Although this kind of sucrose battery is not very efficient, the valuable thing is that the power it stores will not be lost over time, which absolutely crushes lithium-ion batteries. In addition, since the volume of carbon nanotubes in this technology can be reduced, sugar batteries can also be used in wearable devices in the future.

Air charging

Researchers at the University of Washington's Sensing Laboratory have created the Wireless Identification and Sensing Platform (WISp): a combination of sensors and computing chips that operates without batteries or power cords.

It absorbs radio waves emitted by an RFID (radio frequency identification) reader and converts them into electrical current.

It has similar clock speeds and features to the processor in the Fitbit, including an embedded accelerometer and temperature sensor. It does this by backscattering wireless signals.

Its bandwidth is similar to Bluetooth Low Energy, a wireless charging technology that powers most Bluetooth speakers and wireless headphones. For example, installing WISp into a fitness tracker allows you to download new tracking features or update to fix bugs without having to connect it to a device.

By combining WISp and RFID readers, researchers say they have been able to create a battery-free computer that is 10 times faster.

However, using radio waves to charge iPhones and laptops is still a long way off.

However, the fields where WISp can currently be used are: 1. Construction, which can detect whether the building has been damaged in an earthquake; 2. The agricultural field, where the ability to monitor thousands of plants at the same time can bring huge value; 3. Used in Implantable devices to monitor patient health; 4. Fitness bracelets. Most importantly, WISp and other battery-free computers can make IoT devices smart.
