In recent years, with the rapid development of new energy vehicles, energy storage equipment and other fields, lithium batteries have been widely used in various fields as a high energy density, lightweight and portable battery.
However, due to its safety risks, high cost, and resource scarcity, scientists have been trying to find a safer and environmentally friendly alternative. Recently, a new type of metal-ion battery known as "water battery" has attracted widespread attention, and some experts say that this battery is expected to replace lithium-ion batteries in the next five years and become the mainstream battery for new energy vehicles and energy storage equipment, becoming the development direction of the next decade.
According to **, scientists from Liaoning University in Shenyang and RMIT University in Australia have jointly developed a "water-based metal-ion battery", referred to as "water battery". The energy density of such a battery is about 75 watt-hours per kilogram, which is equivalent to 30% of the most **Tesla car batteries. Scientists say that by further developing new nanomaterials as electrodes, this value is expected to be significantly increased in the future. The manufacturing process of this "water battery" is relatively simple, and the materials required are abundant in nature, so it is inexpensive and less toxic. Moreover, the current version of the "water battery" can avoid potential safety hazards such as ignition and explosion, and can also be easily disassembled so that the material can be reused.
In short, the emergence of "water batteries" has brought safer, environmentally friendly and sustainable energy solutions to people, and promoted the green development of human society.
