Charging efficiency, charging pile/substation layout, battery life, these 4 points have always been the "problem of the century" that plagues pure electric vehicles. However, it is gratifying that these problems have not hindered the progress of pure electric vehicles, but have stimulated the "creative passion" of the new car-making forces. Since the slow charging efficiency cannot be directly solved for the time being, then we will retreat to the second place, adopt the policy of "curve to save the country", help and remedy from the side, and the idea of changing the power station and improving battery life was born, and it is being carried out in an orderly manner.
It is worth noting that although the emergence of the current substation can indeed solve the problem of charging efficiency, but because of the imperfect layout of its substation, there will still be a problem of queuing for the replacement of the power station in major cities, and because of the limited number of battery blocks of a substation, it is still necessary to wait after being replaced, which returns to our essential problem - charging efficiency. Therefore, we can see that if we cannot provide enough substations and power exchange blocks, the problem of charging efficiency is still a symptom or a cure.
Because the layout of the replacement power station requires a lot of capital investment, there are few "investors" with strength and courage at present, so as far as the current situation is concerned, it is necessary to carry out a "two-pronged" strategy, since the replacement power station is constrained by practical problems, then at the same time research and development of batteries, increasing the mileage is also a proper way to deal with, and the car battery itself also needs to be continuously re-evolved.
For the battery mileage, there are several new car-making forces have made revolutionary breakthroughs on this basis, GAC Aion LX PLUS released by the highest official version can reach 1008km, the battery technology name is sponge silicon anode sheet. There is also a battery manufacturer Our Next Energy (ONE) with its own battery for tesla Model S to do a battery test, the cruising range directly reached 1210km.
In fact, as early as before, Tesla had mentioned the new battery it was developing at the Battery Day in 2020 - the 4680 battery, although Tesla did not announce how much battery life the 4680 battery could achieve at that time, but from Musk's introduction, we can know that the 4680 battery will be a revolutionary breakthrough for Tesla.
The full name of the 4680 battery is the 4680 type electrodeless ear battery, compared with the current mainstream car battery, its advantages are very clear.
The increased heat generation and dissipation capacity of the battery will increase the cycle life of the battery.
The battery energy density is increased and the cruising range is increased
In short, the 4680 type electrodeless ear battery is not only durable, but also the mileage has been significantly improved. According to the latest reports, Panasonic has taken the lead in building a battery production line in Japan, planning to invest $700 million to supply Tesla with 4680 batteries in 2023.
In fact, not only Panasonic, but also Ningde Times, Samsung, LG have clearly stated that the production of 4680 batteries for Tesla is their goal, it is conceivable that the forward-looking of 4680 batteries is high, and can provoke many mainstream battery manufacturers to "pursue"! Of course, this must also involve interests, after all, in the field of pure electric vehicles, Tesla's sales have always been high, if you can provide batteries for it, then the "cake" must be divided a lot.
Write at the end
The emergence of 4680 batteries means another wave of "inner rolls" in the pure electric vehicle industry, and it is estimated that in the near future, more and more emerging batteries will appear on the market. For the industry, this is a good thing, because it means that the pure electric vehicle industry is in a virtuous circle.
