Research division of IBM has developed a new battery type. It is cheaper than existing lithium-ion counterparts, less flammable and charge to 80% in five minutes, and components for their production can be obtained from the usual sea water.
Batteries without heavy metals
IBM Research has developed a battery of new materials, which a number of characteristics much superior to today’s common lithium-ion batteries. This is stated in the message posted in the blog of the research division of the company (IBM Research) on its official website.
In today’s batteries, which are used in a number of devices ranging from fitness bracelets and smart phones to electric vehicles, often used heavy metals, in particular cobalt and Nickel. For example, in lithium-ion batteries, the cathode (negative electrode) may be executed from cobaltate lithium or lithium nikeeta. By themselves, these metals may pose a threat to human health and the environment. In addition, their stocks are limited and the extraction of cobalt, according to the Financial Times, uses child labor.
A new IBM technology involves the creation of the battery on the basis of three new materials, including heavy metals there. The chemical composition of the materials from which is made the anode, cathode and liquid electrolyte, the researchers did not disclose, however, assure that the necessary materials can be obtained from common sea water and the fact that they are much cheaper used in modern lithium-ion batteries.
The benefits of new technology
According to experts of IBM Research their design is superior to lithium-ion technology for many important parameters. So, if you believe the scientists, their battery can be recharged to 80% in five minutes, with the possibility of ignition of such a device is significantly lower compared to Li-ion counterparts. The latter lower the temperature of ignition.
The energy density of the innovations is comparable with the best samples of lithium-ion batteries (more than 800 WH/l), and its energy efficiency exceeds 90%.
In addition, the researchers say that their tests showed the possibility of applying this technology in the manufacture of batteries with very long life, but does not give any specific data on this subject.
The scope of IBM batteries
Researchers believe that products based on the developed technology could find application in energy, car and aircraft manufacturing.
Despite the fact that the studies are at an early stage, IBM Research signed contracts for the joint development of a new generation of batteries and infrastructure for the improvement and production of Mercedes-Benz Research, Central Glass (manufacturer of electrolytes) and Sidus (manufacturer batteries).
Not without the help of artificial intelligence
IBM Research also reports that in its work, the team uses the technology of artificial intelligence (AI), called semantic enrichment. She applied for further improvement of the battery performance through identifying the most appropriate and safe materials.
There are other technologies that can replace lithium batteries, and put an end to their not the most environmentally friendly and ethical production and recycling.
In December there was news that scientists from the University of Illinois at Chicago have developed a new technology for the production of batteries for mobile devices, which is based on the principle of using an unordered particles of magnesium oxide and magnesium anode directly.
Another group of American scientists, this time from Caltech, has created a battery based on fluoride – chemical compounds of fluorine with other elements of the periodic table. Similar battery in theory are characterized by their ability to hold a charge up to eight times longer compared to lithium-ion and lithium-polymer. Again, they are much safer nepodvijnosti thereof due to the influence of increased ambient temperature or heating during recharging.
In November 2018, it became known that China started the production of batteries with solid electrolyte, which in the foreseeable future can become part of mobile equipment and vehicles. It was assumed that they will replace lithium-ion batteries due to the greater compactness and security.
