AA rechargeable battery

Five innovative battery technologies: AA rechargeable battery have great potential for environmental protection

According to foreign media reports, batteries have been integrated into our daily lives. Electric cars, flashlights, remote controls, it seems that our lives have long been inseparable from batteries. Fortunately, future batteries are moving in a sustainable direction. The editor has compiled five examples of future innovative battery technologies for readers to appreciate, as follows:

1. New batteries powered by human skin

Today, "smart wearables" such as smart watches, Bluetooth headsets, and smart clothing are becoming more and more popular. The above devices can track and record the user's breathing, heart rate and other body parameters. To solve the power supply problem of the above wearable devices, researchers are developing a battery whose electrodes are attached to the user's skin.

Currently, this innovative battery is being tested. When a finger taps the skin, the electricity generated can light up 12 LED bulbs. It is worth mentioning that the electrode can capture the current on the skin. Its gold film layer is 50 nanometers thick and is located under the silicone rubber layer, which is composed of many small pillars, thereby increasing the skin contact surface.

2. Quick-Charge Technology

Not long ago, if a smartphone ran out of power, it meant that the user needed to plug the phone into a charger and wait 30-60 minutes to fully charge the device. Today, some fast-charging technologies can reduce the charging speed to one-sixth of the previous speed. For example: Qualcomm's "5for5" innovative technology highlights "charge for five minutes, talk for five hours", which aims to provide ultra-fast charging services for mobile phones and smart devices using Snapdragon chips, which not only greatly reduces the charging time, but also avoids waiting for charging. In addition, this technology also slows down power consumption and reduces the electricity bills required.

3. Safer solid-state batteries

Researchers have developed several solid-state batteries that are ahead of the currently commonly used AA rechargeable battery in many aspects. In addition, solid-state batteries are safer, have a longer service life, and are more powerful. These new rechargeable batteries can be recharged hundreds of thousands of times and then landfilled after the materials wear out. Solid-state batteries increase the power by more than 30%, which means that after charging, they can be used for longer. Because solid-state rechargeable batteries are non-flammable, they are an excellent type of on-board battery for electric vehicles.

4. AA rechargeable battery

Although solid-state batteries can provide various environmental protection functions, VisualCapitalist believes that AA rechargeable battery have a lot of room for improvement in environmental protection. It is estimated that the power of AA rechargeable battery will increase by 6%-7% year by year in the future, thanks to the continuous adjustment of the content of metals such as aluminum, cobalt, manganese, and nickel in the cathode of AA rechargeable battery. Researchers have conducted a lot of experiments on the above materials and continue to explore the best ratio of each material to extend the service life of the cathode while improving its energy efficiency. Currently, researchers are testing silicon anodes, which increase the battery power by 10 times compared to the current graphite anodes.

5. Flexible battery

Inspired by the Japanese origami technique, the research team at Arizona State University adopted a flexible energy storage technology. The lithium-ion battery they developed has a large number of folds and cuts, which enhances the battery's ductility and flexibility.

It is said that the appearance of this flexible battery is an elastic wristband, which is one of the important components of smart watches. Due to the ductility of the wristband, this type of stretchable Eurostar battery may be sewn into smart clothes. Smart wearable devices may eventually be powered by this type of battery, which consumes fewer resources than traditional bulk batteries.
