Electric cars are becoming more popular day by day, but in the meantime, some users are worried about the durability of lithium-ion batteries in these cars. For this reason, huge sums of money are currently being spent on the development of new batteries. One such technology is the aluminum-air battery, which offers attractive benefits for electric vehicles. But are these batteries really practical or are they just a lot of hype?

What is an aluminum-air battery?

Electric cars are very important. have found because they bring significant benefits. But as we said, concern about the safety and life of lithium-ion batteries has partially stopped the growth of the market for these cars. Although lithium-ion batteries have improved significantly in recent years, ultimately cars based on these batteries can travel up to 650 kilometers per charge.

Among the most important weaknesses of electric cars is the way to charge them, which usually takes a long time and therefore creates many challenges for traveling. But aluminum-air batteries can solve many of these problems because they don't need to be charged.

The concept of these batteries goes back to the 1960s. But at that time, because the electrolyte used was dangerous and toxic, it was not possible to use this battery commercially. But in 2001, Trevor Jackson, a British naval engineering officer, decided to make these batteries safe for commercial use.

Current electric car batteries have two electrodes, a cathode and an anode, which They are made of different materials and there is an electrolyte between them. When a battery is used, ions flow from the anode through the electrolyte to the cathode. During charging, ions flow in the opposite direction to the anode.

Aluminum-air batteries act like a fuel cell. Specifically, aluminum is used for the anode and oxygen is used for the cathode. As a result, these types of batteries provide a much higher energy density. Anode releases electrons by oxidizing aluminum, and while the cathode reduces oxygen, more electrons are released, resulting in the production of electrical energy. Finally, a white powder is formed on the anode.

Advantages and disadvantages of aluminum-air batteries

Aluminum is the third most common natural resource in the earth's crust and the most abundant metal. is considered; Therefore, we will not face the problem of lack of this metal for many years. Aluminum is considered a soft metal and is stable unlike lithium. We should also mention its cheapness, less pollution for the environment, non-toxicity and high recycling capability.

As we said a little earlier, this type of battery is not rechargeable. Also, considering that silver metal plays an important role in this battery, the production costs of aluminum-air batteries are largely influenced by the price of silver.

Problems of lithium-ion batteries

Lithium-ion batteries use lithium, nickel and cobalt materials. All of which are rare metals and can only be found in certain parts of the world. Currently, electric cars make up only 6% of the car market, and even now a large amount of these metals are extracted. Therefore, if the market share of these cars reaches 50 or even higher, there will certainly be more challenges in this field. Among other disadvantages of these types of batteries, we can mention the high price, the instability of lithium and the extensive negative effects on the environment.

Battery replacement versus charging

Given that aluminum-air batteries are not rechargeable and must be replaced, the benefits and Let's talk about the disadvantages of switching versus charging. Some companies have estimated that the entire process of replacing a car's aluminum-air battery only takes about 3 minutes. Aluminum-air batteries are said to last for around 8,700 km.

But the real question is why a buyer should prefer replacing a battery over charging it. First of all, we should mention the much higher durability of aluminum-air batteries. This means that users need to replace the car after using it for a long time. Also, in the end, the cost of replacing these batteries will be very low, and as a result, their attractiveness will be doubled.

Will aluminum-air batteries become widespread?

Right now It is also possible to use these batteries for electric cars. But it is still a popular option It can't be done, but until then, they can be used as spare batteries for lithium-ion batteries so that if the battery runs out halfway, this spare battery can be used to continue the journey.

Finally, this Technologies are opening the hands of electric car buyers, and this is a matter for everyone's benefit. Thanks to these innovations, in the near future we will see more widespread use of electric cars.
