Charge Your Life with New Battery Technologies
Electricity has been serving the humanity for three centuries. Humans learned not only to produce energy through artificial means but also to collect in the vault. Every day we use batteries in the most diverse spheres of life. In the modern world of technology and gadgets, batteries are one of the most sought-after inventions.
While corporations are keen to produce appliances with less electricity consumption, we often face the need to recharge our smartphone or laptop. Check out my-custom-essays.com while there is an opportunity to save the charge of your laptop. At the time when you are studying, scientists and engineers are developing new approaches to the accumulation of energy. Now you will always be charged.
The basis of a battery operation is chemical reactions. Usually, this is a closed system where all processes with components occur. The work of metal-air batteries is based on the air for the oxidation of various metals, which comes from outside.
Lithium-oxygen chemical current meters are one of the most promising options for replacing lithium-ion batteries. The principle of operation is based on the reaction of lithium with oxygen and the formation of lithium peroxide. Such batteries have energy 5 times greater than that of ion batteries.
The main problem is that such batteries are sensitive to the composition of air. However, American scientists have developed a protective coating for the anode and nano-constructed cathode. The experiments show that alithium-oxygen battery can withstand at least 700 recharging cycles without dropping the capacitance, and the chemical composition of the electrodes does not practically change.
Accumulators for Cars
The number of electric cars is growing every year. An accumulator is an important constituent of such machines. Therefore, the improvement of batteries for cars is an actively developing direction.
One possible option is a battery based on sodium. The capacity of such a battery is two times more than the current one, in addition, it is very quickly charged. An electric car can be charged in 5 minutes. This technology can become very popular in the near future since the cost of lithium exceeds the cost of the enterprise tens of times.
Many experts believe that the future is in graphene batteries. Graphene appeared in 2004. However, the power consumption of batteries based on it is simply amazing. You need only 8 minutes for a full charge, and the mileage of the car is 1000 km. The experimental samples were successfully tested for BMW cars. In comparison with existing analogs, graphene batteries are 4 times lighter and more durable. Graphene is a cheap environmentally friendly material that is easy to obtain, which reduces the cost of an auto.
Nanotechnology in Energy Storage
The gradual loss of capacity by a battery is one of the most urgent problems of the industry. Modern lithium-ion batteries, as their developers promise, can withstand approximately 500-1000 cycles of recharge. But the discovery of researchers at the University of California can help increase the life cycle of batteries in tens and hundreds of times.
Scientists managed to achieve a significant increase in a battery lifespan by replacing the liquid electrolyte with gel electrolyte in a battery with gold nanowires. The nanowires themselves are covered with a layer of manganese dioxide. Initially, it was an experiment using nanotechnology in batteries. But in the course of the research, the inventors unexpectedly found that the capacity of the batteries does not decrease after numerous uses.
The science still fails to find an explanation for this. The current output after 100 thousand cycles remains at 96%. The serial production of new batteries is not on the way yet. The main reasons are:
- An unprocessed way of production
- The use of gold
- The use of nanowires
- The high complexity of the product
Scientists from Florida transform an electric cable to an energy storage tool. They took a cable wire and got it covered with multiple tiny nanowires. As a result, it works like a battery. This helps to save space. A nanowires battery can go through charing 10,000 times compared to 1000 for lithium.
Some innovations have already been successfully applied, others are only at the development stage. The modern life dictates its own conditions and the market accumulation and storage of energy cannot lag behind. Developments in the field of accumulators and batteries are becoming increasingly in demand. It’s not surprising because they will have a huge impact on the future energy consumption.
