Lithium iron phosphate battery and three lithium battery，which is good?

At this stage, the new energy vehicle driving force battery for resale in the sales market is all made of lithium iron phosphate battery, in which lithium iron phosphate battery can be divided into lithium iron phosphate battery and three lithium battery two kinds, but most of the customers are not professional, also do not know which lithium iron phosphate battery and three lithium battery is good? Today, let's interpret the distinction and service life of lithium iron phosphate battery and ternary lithium battery.

What is a lithium iron phosphate battery?

Lithium iron phosphate battery is a kind of lithium iron phosphate battery, which refers to the lithium iron phosphate as the cathode material of the battery. Features are safety and reliability, heat resistance, and good circulation system performance.

What is a ternary lithium battery?

Ternary lithium battery is also known as "ternary polymer lithium battery", which refers to lithium nickel-cobalt-manganese acid or lithium nickel-cobalt-aluminate lithium battery as cathode material. Because the ternary lithium battery has a smaller volume and a higher working capacity, it is widely used in new energy vehicles at the present stage. For example, Tesla is known to all. All the vehicle systems of the Group use ternary lithium batteries.

Iron phosphate lithium battery and three lithium battery which good?

1. Battery-specific energy

Ternary lithium > lithium iron phosphate

In simple terms, it is the case of enterprise volume or gross weight, three lithium batteries can store a large amount of electricity consumption, and the mileage of the car will be higher. This is also because of the metal electrode difference between the two, lithium iron phosphate battery cathode material is lithium iron phosphate, and ternary lithium battery is nickel cobalt manganese or nickel cobalt aluminum. The different organic chemical properties make the specific energy of ternary lithium battery with the same quality 1.7 times that of lithium iron phosphate.

2. Safety performance

Lithium iron phosphate > ternary lithium

In the current stage of popular car batteries, lithium iron phosphate heat resistance is the most outstanding. When the ambient temperature reaches 600℃, it gradually dissolves. In contrast, ternary lithium batteries gradually melt at 300℃ or so. In the fire things, it is indeed three yuan lithium battery car accounted for a higher proportion.

3, ultra-low temperature performance

Ternary lithium > lithium iron phosphate

The new energy vehicle in the cruise mileage attenuation thing has become the default setting of the field. The performance of lithium iron phosphate battery is inferior to lithium ternary at ultra-low temperatures. Lithium iron phosphate in -10℃ battery volume attenuation to about 50%, the number can not exceed -20℃ work. The lower limit of ternary lithium is -30℃, and the attenuation level is smaller than that of lithium iron phosphate at the same temperature.

4. Term of use

Lithium iron phosphate > ternary lithium

Car batteries, like those in mobile phones, use less energy as their contents undergo several reactions. Lithium iron phosphate can be recharged 3, 500 times before falling to 80% of the mandatory replacement limit, which is estimated to last for more than a decade. Ternary lithium battery has already decayed to the specified value within 2000 times of charge, and this is only about six years of application.

Evaluation: Ternary lithium battery is suitable for new energy buses, lithium iron phosphate battery is suitable for buses, and it will be a solid battery world in the future.

The battery safety performance, relative density volume, service life, ultra-low temperature performance, and other main performance aspects. Both have their own advantages, with lithium iron phosphate as a symbol of BYD cars, feel the safer performance. Tesla uses a ternary lithium battery, which has obvious endurance advantages. A weak spot in the range can cause customers to subconsciously overlook other advantages. Since BYD cars gradually use ternary lithium batteries, the ultimate battle between the two batteries is also a perfect end. Only to show that in the family car industry, the overall performance of ternary lithium batteries is obviously more to meet the needs of the market.

[Unscientific application can lead to shorter life]

Whether it is a lithium iron phosphate battery, or ternary lithium battery, no matter how the battery technology, if not the scientific application is caused by battery attenuation, and then harms the battery life, the following aspects should be paid attention to as far as possible:

1. Charge quickly and often. Many new energy vehicles are suitable for fast charging, so many drivers will choose fast charging, in a short period of time the car charges a certain amount of electricity, to ensure that everything is safe and normal driving. Fast charging is a good function, but often the application of fast charging will reduce the recovery ability of the battery, and then reduce the frequency of battery charging, causing certain damage to the battery.

2, ultra-low temperature long-term placement. At this stage, the new energy vehicle battery for re-sale on the market is divided into three lithium batteries and lithium iron phosphate batteries. However, they are not the same in dealing with ultra-low temperature, no matter which kind of battery technology, there is battery attenuation in dealing with ultra-low temperature natural environment.

3, often low power mode battery charging. Because the lithium iron phosphate battery will not have battery memory, so the pure electric car is like everyone's smartphone, use at any time with use, as far as possible do not consume all the electricity in the battery charging.

4, bigfoot plug-in accelerator pedal. Because a pure electric car has a feature, it is to speed up the performance is extraordinary, so part of the car buyers loves the bigfoot plug-in accelerator pedal, and then the handling. But to be clear, a large current will make the battery resistance greatly increased, often so safe driving and may harm the battery
