Which is better, a lithium battery or a lithium iron phosphate battery?

Lithium iron phosphate batteries are good.

1. Lithium iron phosphate batteries have a stable chemical structure and high temperature performance. Lithium iron phosphate batteries are not easy to catch fire or explode under abnormal conditions such as high temperature or short circuit; Lithium batteries are safer than lithium iron phosphate batteries which are slightly inferior.

2. The number of charge and discharge cycles of lithium iron phosphate batteries is not less than 2,000 times, while the number of charge and discharge cycles of lithium batteries is about 800 times. This means that lithium iron phosphate batteries have a longer lifespan and can be used continuously for more than 10 years.

Which is betterlleure, a ternary lithium battery or a lithium iron phosphate battery?

I discovered ternary batteries Lithium batteries and lithium iron phosphate batteries each have their own advantages and disadvantages, depending on the situation, for example:

Energy density: the energy density of ternary lithium batteries. is higher than that of lithium iron phosphate batteries.

Safety: Lithium iron phosphate batteries are safer than ternary lithium batteries.

Lifespan: The lifespan of lithium iron phosphate batteries is better than that of ternary lithium batteries.

In addition, I also learned that lithium iron phosphate batteries have low raw material costs, support fast charging, wide operating temperature range and stability. They are the best among current automotive lithium batteries and aremore suitable. our needs for low cost and high security scenarios, such as energy storage systems, power tools, etc. The advantage of ternary lithium battery is that it is more stable at low temperatures and suitable for northern weather conditions. It is suitable for scenarios where we need high energy density and fast charging, such as electric vehicles, electric bicycles, etc.

Which iron battery, lithium battery or nickel battery is better?

The performance of lithium battery is better and The capacity of the lithium battery is large, 14,500 is generally equivalent to 800 mAh, 14,500 lithium iron phosphate is generally equivalent to 600 mAh, plus the rated voltage of 3.6V of the lithium battery, the energy of total discharge is almost 150% of lithium iron phosphate. The voltage is close to 3V, which makes it easier to use.Lithium iron phosphate has good resistance to overcharge and overdischarge and generally does not require a protective plate when used in a single section.

Lithium iron phosphate batteryPrinciple and structure:

1. Commercial lithium iron phosphate battery generally consists of the following parts: Positive electrode material (lithium iron phosphate), negative electrode material (graphite), as well as aluminum foil (positive), copper foil (negative ) as positive and negative current collectors, and positive and negative electrode tabs (i.e. leads from the current collector).

2. There are also separators, electrolytes, aluminum-plastic films and battery protection plates. It adopts winding type and is made into 18650 type battery.

3. The principle is that during discharge, the ions Li migrate from the negative electrode to the positive electrode; and during charging, Li ions migrate from the positive electrode to the negative electrode. .

Iron battery

At present , domestic batteriesThere are two types of iron batteries studied abroad: high iron batteries and lithium iron batteries:

1. High iron batteries are based on the synthesis of stable ferrates (K2FeO4, BaFeO4, etc.), which can be used as cathode materials for high iron batteries to increase energy density. A new chemical battery with large size, small size, light weight, long life and no pollution.

2. The full name of lithium iron battery is lithium iron phosphate battery. Because its performance is particularly suitables to electrical applications, some people also call it "lithium iron battery". (Hereinafter referred to as "lithium iron battery")

Lithium battery

Lithium battery is a type of battery that uses lithium metal or lithium alloy as negative electrode material and uses a non-aqueous electrolyte solution.

Nickel battery

Alkaline battery using nickel hydroxide as positive active material.

The current mainstream in China is lithium iron battery

The advantages are as follows:

A.

High energy density

p>

The weight of lithium-ion batteries is half that of nickel-cadmium or nickel-metal hydride batteries of the same capacity, and the volume is 20-30% of nickel-cadmium and 35 to 50% nickel-metal hydride.

B.

High voltage

The operating voltage of a lithium-i battery cellone is 3.7V (on average), which is equivalent to three nickel-cadmium batteries. batteries connected in series or NiMH batteries.

C.

Pollution-free

Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead and mercury.

D.

Does not contain lithium metal

Lithium-ion batteries do not contain lithium metal, so they are not subject to regulatory regulations. air transport banning the limited carriage of lithium batteries on passenger planes.

E.

Long lifespan

Under normal conditions, the charge and discharge cycles of lithium-ion batteries can exceed 500 times that of phosphate of lithium iron (below). called phosphorus iron) can reach 2000 times.

F.

No memory effect

The memory effect refers to the phenomenon that the battery capacity decreases during the charge and discharge cycle batsnickel-cadmium teries. This effect does not exist with lithium-ion batteries.

G.

Fast charging

Using a constant current and constant voltage charger with a rated voltage of 4.2V, the lithium-ion battery ion can be charged to 1.5--2.5 It can be fully charged in one hour; the new lithium iron phosphate battery can already be fully charged in 35 minutes.

Ternary lithium batteries are better than lithium iron phosphate batteries.

Ternary lithium batteries have higher energy density, higher battery capacity, longer life and better safety performance. Although lithium iron phosphate batteries are also relatively safe, ternary lithium batteries perform better at higher temperatures and charge faster, making them suitable for a wider range of application scenarios.ation. Lithium iron phosphate batteries and ternary lithium batteries are currently widely used battery types. Although both batteries have their advantages.

However, ternary lithium batteries have great advantages in energy density, battery capacity, service life and It is better than lithium iron phosphate battery in terms of safety and reliability. other aspects. At the same time, ternary lithium batteries charge faster and are suitable for a wider range of application scenarios. In addition to lithium iron phosphate batteries and ternary lithium batteries, there are currently other types of batteries, such as lithium cobalt oxide batteries, lithium manganate batteries, etc. Different types of batteries have different characteristics and applicable scenarios, and should be selected according to specific needs.

Performance of ternary lithium battery:

Lithium ion battery is a chemical battery that uses lithium as a negative active material. Lithium has the most negative standard electrode potential, the lightest density among metals, and the highest reactivity. Therefore, the electromotive force and specific energy of lithium batteries are very high and are an important high-energy battery. The positive active materials of lithium batteries include inorganic electrode materials such as oxides, sulfides, halides, halogens and oxygen-containing acid salts. Ternary polymer lithium battery refers to a ternary lithium battery whose positive electrode material uses lithium nickel cobalt manganese or lithium nickel cobalt aluminate.

A relatively balanced material in terms of capacity and safety, and offeringt better cycle performance than normal lithium cobalt oxide. At the beginning, for technical reasons, its rated voltage was only 3.5-3.6 V, and its usage range was limited. With the continuous improvement of the formula and the improvement of the structure, the rated voltage of the battery has reached 3.7V and the capacity has reached or exceeded the level of lithium cobalt oxide batteries.
