This article compares the advantages and disadvantages of lithium-ion battery packs and ternary lithium-ion batteries

This article compares the advantages and disadvantages of lithium-ion battery packs and ternary lithium-ion batteries. There are many types of batteries, including lithium-ion battery packs and ternary lithium-ion batteries, both of which are the core of electric vehicles. Many people ask Little Makeup, which is better, lithium iron phosphate battery pack or tri lithium ion battery? What are their strengths and weaknesses? So let's give you a complete understanding through this article.

Concept of Lithium Iron Phosphate Battery Pack:

Lithium iron phosphate battery pack refers to a lithium-ion battery with lithium iron phosphate as the positive electrode material. Because its function is particularly suitable for the use of power sources, the term power source is referred to as appassification, which stands for lithium iron phosphate power batteries. Compared with traditional lead-acid batteries that do not contain precious metal elements, lithium-ion battery packs have significant advantages in operating voltage, energy density, cycle life, and high temperature resistance.

Concept of ternary lithium-ion battery:

Ternary polymer lithium-ion batteries are lithium-ion batteries with lithium nickel cobalt manganese or lithium nickel cobalt aluminate as positive electrode materials and graphite as negative electrode materials. Ternary lithium-ion batteries have high specific energy and power. Ternary lithium-ion batteries also have significant advantages in high-capacity charging and low temperature resistance.

Advantages and disadvantages of lithium iron phosphate battery pack

The benefits of packaging lithium-ion batteries

Good high temperature performance: The thermal peak of the lithium iron phosphate battery pack can reach 350 ℃ -500 ℃, and the working temperature range is wide from -20c to 75C.

Long life: Lithium iron phosphate power lithium battery, with a cycle life of over 2000 times and a standard charging speed of 5 hours, can reach 2000 times.

high-capacity. Lithium iron phosphate battery packs can store 2 to 3 times more energy than carbonate batteries of the same capacity.

Small size and light weight: The volume of the standard lithium iron phosphate battery pack with equal capacity is 2/3 of the volume of a lead-acid battery, and the weight is 1/3 of the volume of a lead-acid battery, making it relatively light.

Safety and environmental protection: The packaging of lithium iron phosphate batteries has passed strict safety inspections and will not explode even in severe collisions; It does not contain any heavy metals or rare metals, is non-toxic, and is pollution-free in both production and use.

No recall effect: Under what circumstances can lithium-ion battery packs be used with impact without the need for full charging.

Fast charging: Use a dedicated charger to fully charge the battery after 40 minutes of charging at 1.5C.

2. Disadvantages of lithium-ion battery packs

The high cost of material preparation and battery production, as well as the low yield of battery products, will result in high costs per unit of energy storage.

Lithium ion battery packs have poor low-temperature performance and low vibration density of positive electrode materials. Lithium iron phosphate batteries cannot drive electric vehicles at low temperatures (below 0 ℃), and their density is generally around 0.8~1.3.

The product consistency is poor, and currently there is no domestic lithium iron phosphate material factory that can handle this problem well. In this chaotic response process, it is difficult to ensure the consistency of the response.

Poor conductivity, slow dispersion of lithium ions, high charge and discharge, and low practical specific capacity.

Summary: There is great potential for the interest in lithium iron phosphate battery packs! We are just starting to develop and apply it. The current theme of society and the world is green environmental protection, so there will be great potential for it. Shortcomings will be continuously improved, new technologies will be actively developed, and high-quality products will be produced.

Advantages and disadvantages of ternary lithium-ion batteries

1. The benefits of ternary lithium-ion batteries

High voltage path: The voltage path of ternary materials is significantly higher than that of lithium iron phosphate. High voltage lines can reach 4.2 volts, and discharge paths can reach 3.6 or 3.7 volts.

High energy density: The higher the voltage path, the larger the specific capacity. Therefore, for batteries of the same volume, weight, or even ampere hour, the higher the voltage path of ternary lithium-ion batteries, the longer their lifespan.

The vibration density is higher than that of lithium iron phosphate batteries.

2. Disadvantages of ternary lithium-ion batteries

Poor safety performance, large capacity of ternary batteries, difficult to pass safety tests such as needle punching and overcharging.
