Recently, scientists from Liaoning University in Shenyang and RMIT University in Australia have teamed up to develop a revolutionary battery technology called "water-based metal-ion battery", or "water battery" for short. This battery is not only extremely safe and will never be **or**, but also has the advantages of easy disassembly and reuse.
It is reported that the research team has successfully produced a prototype of a water-based battery for a coin-sized clock, as well as a cylindrical battery similar to an AA or AAA battery. This type of battery works similarly to a conventional battery, storing and releasing energy through the flow of electrons between the positive and negative electrodes. However, unlike conventional batteries, the electrolyte in a water battery is water that contains a certain amount of salt, rather than harmful substances such as sulfuric acid or lithium salts.
Although the current energy density of water batteries is about 75 watt-hours per kilogram, which is only 30% of the most advanced battery in Tesla cars, scientists believe that the energy density of water batteries is expected to be further improved in the future through the continuous development of new nanomaterials as electrodes.
It is worth mentioning that the manufacturing process of water batteries is relatively simple, and the materials required are abundant in nature, which is inexpensive and less toxic. Scientists**, in the next 1 to 3 years, water batteries are expected to replace lead-acid batteries, and in 5 to 10 years, they are more likely to completely replace lithium-ion batteries and become a new generation of mainstream battery technology. This innovation not only brings breakthrough progress in the field of new energy, but also injects new vitality into environmental protection and sustainable development.
