Sodium batteries are harder than lithium batteries.
From the perspective of capacity density and service life alone, it is difficult for sodium batteries to replace lithium batteries. However, due to the cost advantage of sodium-ion batteries, the prospects are still there. very wide, and new energy vehicles are still in the rapid growth period, the lack of lithium resources has held back the entire industry.
However, the rise of sodium batteries can be used as a supplement to lithium batteries, which can accelerate the popularity of new energy vehicles. When the sodium battery industrial chain matures, low-end models such as low-end models. fast electric vehicles and A0 class vehicles will use sodium As for ionic batteries, high-end cars still use sodiumlithium ion batteries, and sodium batteries still cannot replace lithium batteries. Unless lithium resources are exhausted, by then nuclear battery technology is. it is estimated that they have matured.
Disadvantages:
Low energy density of the first generation sodium ions of CATL is only 160 Wh/kg, while the energy density of lithium. CATL iron phosphate The energy density of the ternary lithium battery is 200wh/kg and the energy density of the ternary lithium battery is 240wh/kg. The energy density of the battery is low.
For batteries of the same weight, the cruising range of sodium-ion batteries is only 67% of that of ternary lithium batteries. For consumers concerned about cruising range, the cruising range of sodium-ion batteries is 67%. too short, and the next generation of batsodium-ion ries of the CATL era. The research and development target for battery energy density is 200 Wh/kg, minimizing the gap with lithium batteries.
Will solid-state batteries replace lithium batteries?
Currently, pure electric vehicles are mainly equipped with ternary batteries, and some Models use lithium-phosphoric acid and iron batteries. , both of which are liquid lithium batteries. As a liquid battery, it is more obviously affected by temperature. Especially under low temperature conditions, internal chemical reactions will be inhibited, which will affect energy storage, thereby affecting battery life. To alleviate this situation, many companies have started deploying solid-state batteries. So will solid-state batteries replace lithium batteries?um?
In fact, the so-called solid-state battery is a battery using a solid electrolyte. This type of battery has a wider operating temperature range than liquid batteries, so it is more stable. In addition, precisely through the use of solid electrolytes, the lithium dendrite phenomenon that occurs when using liquid lithium batteries is effectively avoided, and the possibility of thermal runaway is also greatly alleviated. Additionally, solid-state batteries have a higher energy density and can provide longer runtime.
But even so, there is still a long way to go to replace liquid lithium batteries with solid-state batteries. Although solid-state batteries have obvious advantages, disadvantages remain. Compared to liquid batteries, solid-state batteries have lower production costsus high. The cost of liquid lithium batteries is around 200-300 US dollars/kWh. If you use existing technology to make a solid-state battery sufficient to power a smartphone, the cost will reach US$15,000, the cost of a solid-state battery. enough battery to power a car is even higher, which only directly hurts its popularity.
In addition, solid-state batteries use solid electrolytes, and the interface with the electrode material is solid-solid state, so the interface impedance is too large, making it take longer to charge the solid-state battery. As we all know, long charging times are one of the reasons for range anxiety. If this problem cannot be solved effectively, the possibility of solid-state batteries replacing lithium batteries is also low.
So, although the advantages of solid-state batteries are obvious, they will not replace liquid lithium batteries in the short term due to higher production costs and increased interface impedance.

Which lithium batteries are currently used in cell phones? What types of batteries were used in the past?
I don't know at the moment, because the technology has made a lot of progress but is not yet industrialized. Generally speaking, research on solids. State batteries are even more academic in terms of industrialization, because some key technologies involve the core technologies of various enterprises and cannot be obtained, technologies based on technical applications still need to be explored pread before. The so-called solid-state battery, as its name suggests, uses solid materials as electrolytes. Compared with traditional lithium batteries, all-solid-state batteries have obvious advantages. They use solid electrolytes to replace the electrolytes and the films under the same energy are thinner and smaller. Solid-state batteries work on the same principle as traditional lithium batteries. The difference between solid-state lithium batteries is that they use solid materials (such as polymers and inorganic materials) as electrolytes instead of the liquid electrolytes used in traditional lithium batteries. Because it uses a solid electrolyte, it is called a solid-state battery. Lithium batteries have been well received by the new energy automobile industry and have experienced rapid development.considerable performance due to their high energy density, low self-discharge rate, high cycle efficiency and long service life. Lithium batteries are not in perfect condition, because their safety performance is relatively poor during use, and there is a risk of explosion. At the same time, lithium batteries must use protection circuits to prevent batteries from being overcharged or discharged. Analyzing the structure of solid-state batteries and lithium batteries, solid-state batteries are simply a battery that uses solid electrodes and solid electrolytes. From the point of view of solid electrolyte, it is non-flammable, non-corrosive, non-volatile and does not leak. It also overcomes the lithium dendrite phenomenon and is safer. Although solid-state batteries have obvious advantages in terms of structure, itThere is still a way to go before lithium batteries can be replaced.
Hello, dear friend!
Nowadays, lithium batteries are generally used. In the past, there were nickel-cadmium rechargeable batteries, nickel-metal hydride rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, etc.
The lifespan of nickel-cadmium batteries is approximately 300 to 700 times, the recharge times of nickel-metal hydride batteries are generally 400 to 1,000 times, and lithium-ion batteries are 500 to 800 times. The lifespan of a rechargeable battery is not only affected by factors such as the raw materials and manufacturing processes used to make the battery, but it is also closely related to the battery's charging and discharging methods and its actual use. For example, the 6-section HITACHI that someone startedcame into use in 1985.Nickel-cadmium batteries (Hitachi) are still used today, but their capacity has been reduced somewhat.
What is an alkaline zinc-manganese battery? Refers to the zinc-manganese battery developed on the basis of the zinc-manganese battery in the mid-20th century. This is an improved type of zinc-manganese battery. The battery uses an aqueous solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) as the electrolyte. It adopts the negative electrode structure opposite to the zinc-manganese battery. The negative electrode is colloidal paste inside, copper nails are used as. current collectors, and the positive electrode is outside. The active material and conductive material are pressed into a ring shape and connected to the battery shell, and the positive and negative electrodes are separated by a special separator. What parts does a battery consist of? EverythingBattery type consists of four basic components. The four main components are electrodes of two different materials, an electrolyte, a separator and a housing. What is a green battery? Refers to a type of high-performance, non-polluting batteries that have been used in recent years and are under development, including nickel metal hydride batteries and lithium-ion batteries currently in use, mercury-free alkaline zinc-manganese batteries. primary batteries that are promoted, fuel batteries, solar cells (photovoltaic cells), etc.
