From our mobile phones to our smartwatch and our laptops, we are surrounded by devices that use energy from batteries. Today, the battery has a solid and very large component of our technology – but if they can be sensitive, flexible and printed?
Accepting this idea, researchers in Sweden developed a liquid battery that can be molded in different ways. If there is details in the file study Published on April 11 in the journal science, batteries, uses from electrical poles – important electricity materials in batteries – in the form of liquid. Soft structure of novels, paving the design methods that are innovative batteries in the future.
“The battery is the largest component of electronic devices. Today, they are strong and quite large. But with a soft and consistent battery, there are no limitations in the design. It can be combined with electronic devices in a completely different method and adapt to users. “Aiman Rahmanudin users. statement– “The surface is like a toothpaste. The material can be used in 3D printers to create the battery as you want.”
According to the previous statement, trying to achieve a soft and flexible battery depending on mechanical properties, such as sliding connections or rare materials that are needed, which are harmful to the environment in processing. The key to Rahmanudin and his colleague's success is to change the electrode to a liquid form.
In order to understand the importance of this success, it is important to remember how the battery works. K -Battery with electricity Consisting of two different types of metals or electrodes: Opposis and cathode Chemical reactions cause Electrons flow From the anode to the cathode – the process that we call electricity – which can work as it moves, such as lighting, lamps or equipment Large battery has more electric capacity but thicker – and therefore has more concentration.
“We are the first to show that the production capacity is independent from strength.” Rahmanudin, the leader of the soft electronic group of Linköping University at the organic electronic laboratory.
Previous efforts to develop liquid electrode Relying on liquid metal that sometimes hardens by order To skip these problems, the team uses plastic that can carry out electricity – called Congee Gate Polymer – and Liganin, a garbage product in paper production. The battery that occurs can charge more than 500 times, even if it is twice as long as the original length.
Moreover, “because the materials in the battery are polymers, concerts and lignin, there are many raw materials by changing the by -product, such as high -value lignin, such as batteries.
“We have shown that this idea works. But the current voltage has to be improved, 0.9 volts. “Rahmanudin explained for comparison. Standard aa battery Between 1.2 to 1.5 volts and Most smartphones Working between 3.7 and 4.2 volts “. Now, we will see the use of other chemicals to increase voltage.”
In truly destroying the mold, the study will open the door to the kingdom of all new designs for devices that use batteries from batteries.
