　　According to foreign media reports, batteries have been integrated into our daily lives. Electric cars, flashlights, and remote controls seem to be inseparable from batteries in our lives. Fortunately, the batteries of the future are 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

　　Nowadays, "smartwearables" such as smart watches, Bluetooth headsets, and smart clothing are becoming more popular. These devices can track and record the user's breathing, heart rate, and other physical parameters. In order to solve the above-mentioned power supply problem of 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. The thickness of the gold film layer is 50 nanometers, and it is located under the silicone layer (siliconerubberlayer), which is composed of many small pillars to increase the skin contact surface. .

　　2. Quick-Charge Technology (Quick-ChargeTechnology)

　　Not long ago, if the battery of the smart phone runs out, it means that the user needs to plug in the charger for the phone and wait 30-60 minutes to fully charge the device. Nowadays, certain fast charging technologies can shorten the charging speed to one-sixth of the earlier time. For example, the highlight of Qualcomm’s “5for5” innovative technology is “charge for five minutes and talk for 5 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 while charging. In addition, the technology also slows down electricity consumption and reduces the electricity bills that need to be paid.

　　3. Solid-state batteries with higher safety

　　Researchers have developed several solid-state batteries, which lead the current commonly used lithium-ion batteries in many aspects. In addition, solid-state batteries are safer, have a longer service life, and have a more powerful battery. This new type of rechargeable battery can be charged hundreds of thousands of times, and it will be landfilled after the material is worn out. The solid-state battery increases the power by more than 30%, which means that it will last longer after charging. Since solid-state rechargeable batteries are non-flammable, they are an excellent type of on-board battery for electric vehicles.

　　4. Lithium-ion battery

　　Although solid-state batteries can provide various environmental protection functions, VisualCapitalist believes that lithium-ion batteries have more room for improvement in environmental protection. It is estimated that the power of lithium-ion batteries in the future will increase by 6%-7% year by year, thanks to the continuous adjustment of the metal content of aluminum, cobalt, manganese, nickel and other metals in the cathodes of lithium-ion batteries. Researchers have conducted a lot of experiments on the above-mentioned materials, and continue to explore the best ratio of each material to extend the service life of the cathode and improve its energy efficiency. At present, researchers are testing silicon anodes. Compared with the currently used graphite anodes, the material has increased the battery's power by 10 times.

　　5. Flexible battery (flexiblebattery)

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