Friends who are interested in buying new energy electric vehicles have not yet made a move, and now you can really wait.
In the next three to five years, the battery field will usher in a major revolutionary change. now
It has come the moment of global Armageddon, especially on the continent, which is said to have launched a general offensive with the goal of becoming the ultimate winner of the global solid-state battery.
If that's the case, the world's automobiles will be transformed in the next few years.
According to China Daily, the mainland may invest about 6 billion yuan to encourage qualified enterprises to carry out research and development of all-solid-state battery-related technologies.
A total of 6 well-known battery companies, such as CATL, BYD, FAW, SAIC, Weilan New Energy and Geely, are expected to receive financial support at the national level.
After the news was announced, some netizens said that these six companies are now members of the "national team" of solid-state batteries.
In fact, 6 billion yuan is not much, in the entire field of automobile and battery research and development, 6 billion yuan to divide 6 companies, this money in the entire solid-state battery research and development project, is not a big number.
Since this money is not much, why is everyone so concerned?
In fact, the three words of the national team already speak for themselves.
This project grant represents the official attitude of the mainland, the government will vigorously support the research and development of all-solid-state batteries, and at the same time release a signal that all companies that research batteries should appropriately change their development goals, and solid-state batteries are the future trend.
As a new battery technology, after the emergence of the term solid-state battery, every time there is a related technological breakthrough, the news will soon become a hot search.
It can be seen that solid-state batteries are indeed a big hit, and they are expected by everyone.
The power batteries we use now, whether they are electric bicycles at home or new energy electric vehicles, are basically liquid batteries as the power source of these cars.
In particular, new energy electric vehicles use almost all lithium batteries that have been put on the market since the 90s.
Because among the many batteries available at that time, the battery life of lithium batteries was slightly better, so there is a wide market today.
But now everyone often complains that new energy electric vehicles are unsafe, and lithium batteries are easy to catch fire and explode, but in fact, the gap of lithium batteries is still very large.
Because we don't have a substitute battery, we can only improve the safety of lithium batteries as much as possible, and at the same time meet everyone's battery life needs.
According to the China Association of Automobile Manufacturers, the penetration rate of new energy vehicles in mainland China will be 31.6% in 2023 and is expected to approach 40% in 2024.
These data are enough to illustrate the fact that more and more people are beginning to adopt new energy electric vehicles and increase their willingness to buy.
In such a market context, providing more safe and reliable electric vehicles and power sources has become an urgent development demand for battery and automobile companies.
Compared to liquid batteries, solid-state batteries have so many advantages.
First of all, everyone is concerned about the safety issue, some car owners dare not buy new energy electric vehicles, has been insisting on driving gas vehicles. It's not that I'm unwilling to accept new things, it's because I've seen too many cases of new energy vehicle fires on the news, which has generated a certain amount of worry and panic.
It is a well-recognized fact that liquid lithium batteries have certain safety risks.
According to the data released by CCTV News, the probability of fire in domestic new energy vehicles has decreased from 1.85/10,000 in 2021 to 0.96/10,000 in 2023, while the fire rate of fuel vehicles has remained around 1.5/10,000.
Judging from the data, the probability of fire in fuel vehicles is actually higher than that of new energy vehicles.
However, it is difficult to extinguish a fire in a new energy vehicle, and there is a high re-ignition rate, so whenever a new energy vehicle catches fire, it will attract everyone's attention.
Among these new energy vehicle fire cases, CCTV News analyzed more than 270 cases from 2023 to the present, and found that the probability of fire due to collision accounted for 10%, and the proportion of fire in the charging or stationary state exceeded 50%.
Experts explain that in fact, the main reason for most battery fires is the thermal runaway of the battery, such as improper charging behavior, scratching of the bottom tray of the car or long-term soaking in water, which may induce thermal runaway of the battery.
According to experimental data, after the thermal runaway of the car battery, the actual interval between the fire is only 5 minutes, and the maximum temperature in the car will reach 437°C.
If the interval between thermal runaway and fire can be extended to more than 5 minutes, the maximum temperature in the car can be greatly reduced to about 85°C, which can increase the chances of escape for the occupants of the vehicle.
After the thermal runaway of the battery, fire is an inevitable problem for most liquid lithium batteries, and with the current technology, it is almost impossible to solve this major disadvantage of lithium batteries.
If we focus our R&D on solid-state batteries, this problem will be solved perfectly.
Because the electrolyte of solid-state batteries is a solid substance, the internal chemical environment is relatively stable, so it will not be affected by temperature or external factors, which will cause changes in the internal chemical environment, which may cause dangerous situations such as fire and explosion.
It can be said that with the current global level of technology, solid-state batteries are definitely the safest batteries.
If new energy vehicles can be equipped with all-solid-state batteries, then its safety is higher than that of traditional fuel vehicles.
Safety is the topic that everyone is most concerned about, and after solving safety issues, the battery range and performance in extreme environments are the focus of everyone's attention.
The cruising range of liquid lithium batteries is often not very high, and the range of 400 kilometers is a relatively excellent model.
This is because there is limited space left for the battery inside a car, and if you want to increase the range, you must increase the energy density of the battery.
Liquid lithium batteries have always had energy density limitations, not because they cannot be broken through technically, because once this density is exceeded, it is easy to explode, so it is not allowed.
Solid-state batteries do not have this to worry about, because they are inherently safe, and the energy density can naturally be particularly high.
According to surging news reports, Tailan New Energy, one of the national solid-state battery teams, recently announced that the measured energy density of the solid-state battery they developed has exceeded 720Wh/kg.
It is worth noting that although the mainland is ahead of the world in the suppression of solid-state battery energy density, in fact, domestic battery manufacturers are very involuted, and the ultra-high energy density we hear is not the limit of the company's ability, but more like a work report in the process of step-by-step growth.
In other words, in the next three to five years, we will hear about all-solid-state batteries that far exceed high energy densities.
Coupled with the information that the state is ready to invest 6 billion yuan as support, it can be shown that the country is not only supporting everyone to develop solid-state batteries, but also wants to promote the mass production of solid-state batteries.
At that time, the range of the new energy electric vehicle we purchased may easily exceed 1500 kilometers, or even 2000 kilometers, and the solid-state battery performs very well in extreme environments, but there is no need to worry about the winter blizzard, your new energy electric vehicle will lie on its stomach, or because the air conditioner or the temperature is too low, resulting in a great reduction in battery life.
There are also some people who are reluctant to buy new energy electric vehicles because the service life of liquid lithium batteries is limited, and there will be a significant reduction in capacity after a few years.
Solid-state batteries do not have this concern, so some people say that new energy electric vehicles using solid-state batteries can be passed on to three generations in one car, and people are still in the car.
Now the world is competing for the research and development of new technologies for solid-state batteries, and wants to become the absolute king of solid-state battery transformation. Not only because solid-state batteries can be used in new energy electric vehicles, but also in the automotive field to obtain a certain amount of sales.
What's more, the arrival of solid-state batteries may disrupt our energy structure, and almost everything around you that needs a power source can directly use solid-state batteries, not only cars, but even airplanes.
In the future, in this solid-state battery showdown, let's wait and see who can become the final king.
