With the rapid development of lithium battery manufacturing industry in China in the past 15 years, production capacity and market have been expanding, and it has gradually entered the TWH era from GWH era. The equipment, processes, and electrochemical formulations used to produce lithium batteries have become increasingly detailed, producing a number of subtle differences. Customers can choose the most suitable lithium battery according to their specific application, which has become a difficult problem for most of them.
As mentioned above, lithium battery is divided into a variety of lithium battery cells from the material, appearance and electrochemical performance, which determines the quality and use effect of the final battery pack. So before you start your project, choose the most suitable cell according to your own use requirements and use environment and even determine the success or failure of your project.

1.Is choosing the most expensive cell necessarily the best?
Before we get started, even if you’re as rich as a Middle Eastern millionaire who doesn’t care about money at all and only wants to spend the most money on the best things, I suggested it is also necessary for you taking a moment to read the following.
Generally speaking, good quality must be at good price, with the price difference between the pros and cons of the battery, most of the situation is feasible. Eliminate the price trap of bad traders and sell the goods at a high price. I still want to be sure to say to you that the most expensive cell may not be the best choice for you.
Sometimes, you choose a higher price product, is to get better quality assurance, but have you considered that sometimes the quality standards exceed your requirements, in fact, is a waste? , for example, if you are a depth of photography enthusiasts, then will choose expensive SLR camera, so as to meet your ultimate pursuit of photographic effect, but if you just want the pictures of the complete function, your request is only a picture out clear enough and not distortion, so in this case, The camera function of an ordinary smart phone can meet your requirements. Is it an excessive waste to spend more money to buy a SLR camera?
From the point of view of business, it is against the spirit of business to ignore the cost and pursue more profits on the premise of ensuring product quality. Do you accept it?
Now, let’s get back to our lithium batteries. Broadly speaking, the application scenarios of lithium batteries can be divided into two categories. The first is power and the second is energy storage. From a philosophical point of view, we can think of power as man’s transformation of space, we need power to move people or things, and energy storage as man’s transformation of time, we need energy storage to store electricity during the day and then use it at night.
Power and can be used according to the environment of the application of different segments, such as passenger car power, you have to consider the range of passenger cars, in the case of charging infrastructure is not perfect enough to ensure that the car can travel enough mileage and will not cause trouble, in such a demand makes the pursuit of lithium batteries a higher energy density, But even worse is the pursuit of too high an energy density, which makes it easy for the interior of the lithium-ion battery to get out of control and cause a fire. How to achieve higher energy density while keeping it safe has always been a big challenge for lithium-ion battery scientists. In addition, we also need to take into account the use of the environment of passenger cars, such as the car climbing, need lithium batteries to meet the high rate of discharge; For example, if you want to complete charging as soon as possible, you need lithium battery to meet the high charging rate; For example, how to ensure the normal use of lithium batteries when the temperature drops to minus 20℃ in winter…. Too many rigid requirements in the specific use of passenger car power battery must be harsh conditions, so the cost of passenger car power battery is the highest. What about electric buses, airport shuttle bus or golf carts? It is entirely conceivable that because these electric vehicles have enough space to store their batteries, travel in a fixed route, and have little change in the environment to be easily recharged, the power batteries they use do not need to be as good as those of passenger cars. Wouldn’t it be a huge waste if you used expensive passenger car power batteries for buses or ferries? So that’s why I say that choosing the most expensive battery may not be the right choice for you, but the lithium battery that best suits your application scenarios and achieves the best cost performance is the right choice.
2.Is choosing the cheapest cell necessarily the best?
It is a great contradiction to believe that all people want the best for the least amount of money. It’s true that a lower price is more attractive to most people, but the truth is that a low price product can sometimes be a trap that can get you into big trouble. This is especially true for lithium batteries! As we all know, the most important thing about lithium battery products is its safety. When the safety can not be guaranteed, it leads to huge disasters. It is not a problem that simple money can solve. China is the world leader in lithium battery manufacturing, supplying about 75% of the world’s lithium batteries. Meanwhile,China is also the biggest consumer market for lithium battery. In China, the biggest use of lithium batteries is to power passenger cars. As we said, passenger car power batteries are the most demanding. Generally speaking, the replacement life of the power battery for passenger cars is about 5-8 years for LFP and 3-5 years for ternary lithium. These replaced power batteries are not unusable, but they still have commercial value. They can be used for UPS backup power, communication base station backup power, and even energy storage projects. We replace these power cells from passenger cars with what we call “echelon batteries,” also known as Secondhand battery or “C-class battery”. If we use these “C-class battery” correctly, there is no big problem, but there are some bad factories and trading companies in pursuit of higher profits, in this essay, will taste “C-class battery” for renovation in accordance with the new battery to export to abroad, it is a high risk behavior, easily lead to a huge accident, happened in the past few years many times this kind of tragedy. Therefore, through strict national management and legal sanctions, most of these phenomena have been put an end to in China. And a lithium battery, it is not used, but long time inventory, inventory at least more than one year, the battery does not need to be refurbished, in theory they have is a new battery, but the lithium battery of inventory too long on self-discharge phenomenon, has become less for service life, the lithium battery which we call “B-class battery” . For the vast majority of foreign trade companies or pack factories engaged in export, most of them regard “B-class battery” as “A-class battery” and sell it to foreign customers who do not know the inside story. That is why some lithium batteries have a very low price, but those who sell them at the same time have a very high profit. Therefore, when you consult a number of companies lithium battery prices, if some of the low is not normal, you should carefully consider whether the other party is selling you “B-class battery”.
