A real new breakthrough in the automotive industry will come when the batteries will cost less, recharge faster, and increase in capacities at small sizes. It is understood by manufacturers all over the world and continues to invest in promising developments.

The emergence of a new generation of batteries will accelerate the interference of hybrid and electric cars, which, in the near future, are expected to almost completely oust classical vehicles with internal combustion engines.
Aluminum batteries can be less harmful to the environment. In order to realize the possibility of creating such batteries, specialists from the universities of France and New Zealand work on the development of the necessary electrolytes. The most interesting thing is that scientists promise to produce electrolyte on a plant basis. In the event of a goal, technology will be a great alternative. Such products would be non-toxic, flammable and cheap, since aluminum is one of the most widespread metals on Earth.
Molybdenum and sulfur
Texas University experts are working to improve the efficiency and environmental friendliness of using lithium batteries. Lithium-sulfur elements are cheaper to manufacture, have more capacity and less weight. However, sulfur is a bad conductor, and electrodes from it collapse during charging. Researchers have found that when adding molybdenum, sulfur electrodes get normal conductivity and become much stronger. At this stage, they are working to completely eliminate adverse reactions and to prepare the technology for commercial use.
Replace the battery?
Researchers from Switzerland are planning to completely replace the materials used in the electrolyte and electrodes. Titanium nitride is a ceramic material that exhibits high electrical conductivity and potentially replaces lithium-based electrolytes. This electrolyte is easy to make. The graphite as a material for electrodes is planned to be replaced by more accessible polypyrene. But the main advantage is not even in the materials themselves, but in the ability to influence their properties. A combination of titanium and polypyrene nitride allows the creation of so-called "cell bags" - the batteries in a flexible film.
The University of Central Florida has developed a battery with a new type of electrode. It shows excellent conductivity, stable at high temperatures and cheap in manufacturing. It is able to cheapen the batteries and extend the life of their service. Researchers argue that such a battery is capable of working out a thousand recharging cycles at all without degradation of quality. In their model, the traditional cathode is replaced by a thin-film alloy of sulfide of nickel and iron sulfide.
Optimization of technology
The American startup, called 24M, has developed a way by which the electrolyte can be used as a solvent for the application of the active substance. This means that there is no longer any need for coating, drying or restoring solvent, which makes the process much faster, cheaper and less expensive. As a result, the cost of producing battery packs is reduced by 20-50%, and their characteristics are even slightly improved.
Meanwhile, German automakers have focused on shortening the charging time and allowing owners of electric cars to spend less time waiting. So Porsche has recently introduced a prototype of an electric vehicle capable of charging from a 450 kW power plant, more than three times that of the Tesla superchargers known for their efficiency. Thanks to this, German luxury electric cars will be able to receive the charge needed to overcome 100 km in just three minutes. BMW is promising that their model and3 will soon be able to be recharged from a 350 kW power station, which will allow the battery to be recharged from 10% to 80% in just 15 minutes. Voltage of 900 Volts and 500 Amp current provide a charge that is 25,000 times more efficient than the fastest of the existing charges for smartphones.
Why Do I Need to Replace Lithium Ion Batteries?
Modern Li-Ion batteries are relatively affordable and relatively efficient. At the same time, their production is associated with significant environmental problems, although it is imperceptible for consumers. Necessary raw materials are obtained from mines, and after the expiration of their battery life, they are disposed of with significant damage to the environment. That is why hybrid cars at the moment remain the most safe for the environment: on the one hand, they less pollute the air, and on the other - use relatively small batteries.
