The biggest achievements of the battery industry in 2019
Many industrial actors and even ordinary users are following the progress achieved in the design and production of batteries. Battery is known as one of the most important parts in the world of technology, and from car manufacturers to manufacturers of consumer electronics and environmentalists are concerned about the development processes of the battery industry. This year was accompanied by important news about batteries. The technologies that charge an electric car battery in 10 minutes and batteries with the ability to absorb carbon dioxide from the air and grow the largest battery in the world, had important points of the development process of batteries. In the continuation of this Zomit article, we describe the most important revolutionary achievements of 2019 in the field of batteries.

Lithium-ion batteries, which are used today in our mobile devices and other technological equipment such as electric cars, maintain their temperature ideally within a certain range during charging. If the temperature is not maintained in the mentioned range, there is a risk of reducing the life and quality of the battery. If batteries can be charged at a higher temperature while maintaining safety, we gain several advantages. Battery efficiency increases with charging at a higher temperature and we will see a significant decrease in the time connected to the power source.
A group of Penn State University researchers unveiled a new battery in October that was able to withstand more heat. Scientists generally prohibit charging the battery at a temperature of about 60 degrees Celsius; But the researchers’ new device only charges for 10 minutes at such a temperature and then cools down rapidly before any harmful effects of the high temperature.
Revolutionary achievement of the researchers in making a battery with high tolerance depended on the use of thin nickel foil. The nickel foil is attached to the negative terminal of the battery and has the ability to quickly heat up the electrons that pass through the terminal. Using the new design, the researchers were able to safely charge the battery 1,700 times at high temperatures. The efficiency of the new method is defined as impressive. The group of researchers say that with such technology, an electric car can be charged in 10 minutes to drive 320 to 480 kilometers.
Battery charging with carbon dioxide
A group of university researchers In October of this year, MIT introduced a new type of battery that has the ability to collect carbon dioxide from the air. The new battery known as electro-swing uses a group of electrodes coated in a compound called Polyanthraquinone, which can absorb carbon dioxide from the surrounding space.
The carbon dioxide absorption process in a new battery is done naturally when the battery is being charged. The absorption of said substance continues until the electrodes are filled with carbon dioxide. Then, the battery can be discharged to use CO2 molecules for industrial applications. The research team has been able to test the current battery up to 7,000 charge cycles, after which a 30% reduction occurs in the battery. The next development vision will be to reach the capacity of 20 to 50 thousand charging cycles. Yes
The search for ways to optimize battery design also includes exploration to find new elements. Carbon dioxide is one of the materials that scientists have been trying to discover its potential for use in the battery industry for years. Lithium dioxide carbon batteries will have an energy density more than seven times that of lithium ion batteries. Also, the development of the battery with those materials that have more charge cycles has many difficulties.
When carbon dioxide is used in the battery, you will see the unwanted accumulation of carbon in the catalyst during the charging process. In September, scientists from the University of Illinois introduced a solution to overcome this problem. They call their new achievement the first rechargeable lithium-carbon battery.
Carbon dioxide rechargeable battery uses molybdenum disulfide nanoparticles in the cathode. In addition, there is a hybrid electrolyte equipped with ionic liquid and dimethyl sulfoxide in this battery. The composition of the mentioned materials prevents the formation of problematic excess carbon in the battery catalyst. The prototype has managed to perform 500 charging cycles so far.
Energy storage at the distribution network level with molten silicon structure
Renewable energies such as wind and Sun produce a lot of power; But the storage of the produced energy for use when necessary requires an optimal design. Australian startup Climate Change Technologies introduced a solution in April that may improve the process of grid-scale energy storage. Leads. Their solution is probably more useful and effective compared to lithium-ion grid storage equipment. Thermal Energy Device or TED was introduced as the world’s first thermal battery. The said device is a modular battery that has the ability to absorb battery from any source and use it to melt silicon in an insulated chamber. Any heat engine can use the generated energy for various applications. Each TED box has the ability to store 1.2 megawatt hours of electricity and by combining them, batteries of unlimited dimensions can be made.
Startup CCT says about the advantages of its new battery that molten silicon does not degrade unlike lithium. Their battery showed no performance degradation in test cycles after three thousand tests. CCT predicts the batteries will last 20 years or more. TED batteries have the possibility of storing up to 6 times more energy than lithium-ion batteries, regardless of their lifespan, and their price will be 60 to 80% of the aforementioned batteries.
Capacity increase with unconventional parts
Lithium-ion batteries have the ability to store and provide the necessary energy to keep your smartphone on for a day or use a laptop for several hours. It should be said that if they are used in the transportation industry, we will face many problems. The energy density of batteries used in cars and airplanes, compared to traditional fuel sources, is the main problem of the transportation industry. In other words, the battery capacity cannot be increased without increasing the weight; As a result, the productivity of the vehicle is reduced.
Researchers from Deakin University in Australia last month presented a solution to overcome the problem of vehicle batteries. Researchers at the Institute of Pioneering Materials of the aforementioned university demonstrated a new type of battery equipped with a solid electrolyte made of commercial polymers.
By using a new battery and discarding the liquid electrolyte that It has risks such as the possibility of fire, it is possible to produce a product with more security . Of course, the capacity of the new design is not limited to these items. The researchers say that the new design makes it possible to use a lithium metal anode, which will lead to doubling the capacity of lithium batteries. The new battery makes electric cars capable of longer journeys. Also, it is possible to produce electric airplanes with the ability to fly to distant destinations. 2017 managed to conclude a contract that will lead to the production of the world’s largest lithium-ion battery. The battery will be built in Australia and will add 129 MWh of energy storage capacity to the region. This battery has the ability to provide 100 MW output.
This year, the Australian government offered Tesla a new contract to add 64.5 megawatt hours of capacity and 50 megawatts of output to its battery. With the new contract, the dimensions of the world’s largest battery will increase by 50% and the said update will be done by the middle of 2020. The mentioned news were the most important achievements of the battery industry last year. As mentioned, batteries are very important in the world of technology and are considered important equipment. Of course, until commercialization, most of the aforementioned achievements need considerable time, and users still have to wait for access to optimal batteries.
