What are the advantages and disadvantages of lithium iron phosphate batteries?

Introduction What are the advantages and disadvantages of lithium iron phosphate batteries? 1. Advantages: 1. Improved safety performance: The PO bond in lithium iron phosphate crystal is stable and difficult to decompose even at high or excessive temperatures.

What are the advantages and disadvantages of lithium iron phosphate batteries?

1. Advantages:

1. Improved safety performance: The P-O bond in lithium iron phosphate crystal is stable and not easy to decompose even at high temperatures or overcharge. like cobalt acid, the lithium-like structure collapses and generates heat or forms strong oxidizing substances, so it has good safety.

2. Improved service life: Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as the positive electrode material. The lifespan of long life lead acid batteries is about 300 times and the maximum is 500 times, while the lifespan of lithium iron phosphate batteries reaches more than 2000 times and can reach 2000 times with one standard charge (5 hours). rate).

2. Disadvantages:

1. The plug density of the positive electrode of the lithium iron phosphate battery is low and lThe density is generally around 0.8 to 1.3. Big size.

2. During the sintering process when preparing lithium iron phosphate, iron oxide can be reduced to elemental iron in a high temperature reducing atmosphere. Elemental iron can cause micro-short circuits in the battery.

Principle and structure of lithium iron phosphate battery:

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. current collector outputs).

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

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

Pacific Automotive Network uses the same battery structure, using ternary materials and lithium iron phosphate materials to manufacture batteries, and conducts discharge, charge tests and cycle under different conditions. It has advantages in charging rate, discharge rate and discharge performance at different temperatures, while lithium iron phosphate material has better cycle performance. It can still maintain more than 80% of the initial capacity after 5000 cycles at 1°C.

With the vigorous development of the new energy vehicle industry, the domestic battery industry is developing rapidly. As a core element of electric vehicles, the configuration of power batteries plays a vital role. Currently, the battery types selected by various automobile manufacturers on the market are roughly divided into two types, one is ternary lithium battery and the other is lithium iron phosphate battery. The differences between the two are as follows.

1. Different properties

1. Lithium iron phosphate battery: onelithium ion battery using lithium iron phosphate as positive electrode material.

2. Ternary lithium battery: lithium batteryThe cathode material is lithium-nickel-cobalt manganate or lithium-nickel-cobalt aluminate ternary cathode material.

2. The main materials are different

1. Lithium iron phosphate battery: The cathode materials of lithium ion batteries mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials and phosphoric acid Lithium iron, etc. Lithium-cobalt oxide is the cathode material of most lithium-ion batteries.

2. Ternary lithium battery: The ternary composite cathode material is composed of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. .

3. Deferbetween applications

1. Lithium iron phosphate battery: large electric vehicles: buses, electric cars, sightseeing buses and light electric vehicles: electric bicycles, golf carts, small flat battery carts, forklifts, cleaning vehicles, electric wheelchairs, etc. power tools: electric drills, chainsaws, lawn mowers, etc.

2. Ternary lithium battery: widely used in mobile and wireless electronic equipment, power tools, hybrid and electric vehicles and other fields.

What will happen if the student's physical examination given after graduation fails?

Failing the university physical examination may affect the student's normal graduation. But don't worry too much. If you pass the physical test, you can still retake the test. If you have nothing to do, go to the playground to run, exercise and improve your fitness. makeup test, it will have no impact.
