Five innovative battery technologies in the future: batteries 9v have huge room for environmental protection

　　According to foreign media reports, batteries have been integrated into our daily lives, such as mobile phones, flashlights, and remote controls. It seems that batteries have long been inseparable from our lives. Fortunately, the future of batteries is developing in a sustainable direction. The editor has compiled five examples of future innovative battery technologies for readers to appreciate, as follows:

　　1. New battery powered by human skin

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

　　Currently, this innovative battery is being tested. When a finger is tapped on the skin, the electricity generated can light up 12 LED bulbs. It is worth mentioning that this electrode can capture current on the skin. Its gold film layer is 50 nanometers thick and is located below the silicone rubber layer. The latter is composed of many small pillars to increase the skin contact area. .

　　2. Quick-ChargeTechnology

　　Not so long ago, if a smartphone ran out of power, it meant users had to plug the phone into a charger and wait 30-60 minutes for the device to fully charge. Today, some fast-charging technologies can reduce charging speeds to one-sixth of what they were earlier. For example: The highlight of Qualcomm's "5for5" innovative technology is "charge in five minutes, talk for 5 hours". It aims to provide ultra-fast charging services for mobile phones and smart devices using Snapdragon chips, which not only greatly reduces charging time, but also avoids No need to wait while charging. Additionally, the technology slows down electricity usage and reduces electricity bills that need to be paid.

　　3. Solid-state batteries with higher safety

　　Researchers have developed several solid-state batteries that are ahead of those currently in common use in several ways. In addition, solid-state batteries are safer, have longer service life, and are more powerful. These new rechargeable batteries can be charged hundreds of thousands of times before being disposed of in landfills when the material wears out. The solid-state battery increases power by more than 30%, which means it lasts longer after charging. Since solid-state rechargeable batteries are non-flammable, they are an excellent vehicle battery for electric vehicles.

　　4.Lithium-ion battery

　　Although solid-state batteries can provide various environmental protection functions, Visual Capitalist believes that lithium-ion batteries have greater room for improvement in environmental protection. It is estimated that the power of lithium-ion batteries will increase by 6%-7% year by year in the future, which is due to the continuous adjustment of the content of aluminum, cobalt, manganese, nickel and other metals in the cathode of lithium-ion batteries. Scientific researchers have conducted a large number of experiments on the above materials and continue to explore the optimal ratio of each material to extend the service life of the cathode and improve its energy efficiency. Currently, researchers are testing silicon anodes, which can increase battery power by 10 times compared to the currently used graphite anodes.

　　5. Flexible battery

　　A research team at Arizona State University used a flexible energy storage technology inspired by Japanese origami techniques. The lithium-ion battery they developed has a large number of folds and cuts, which enhances the ductility and flexibility of the battery.

　　It is said that the flexible battery looks like an elastic wristband and is one of the important components of the smart watch. Due to the stretchability of the wristband, this type of stretchable Ouxing battery may be sewn into smart clothing. Smart wearable devices may eventually be powered by this type of battery, which consumes less resources than traditional bulk batteries.
