New cathode material lithium manganese iron phosphate technology package

1. Project Introduction

Thanks to the global trend of energy conservation and emission reduction and the rapid development of the new energy automobile industry, lithium-ion batteries have been widely used, and people have put forward higher energy and power density requirements for them, and the positive electrode is the key component of lithium-ion batteries, which is an important direction to improve the performance of lithium-ion batteries, and is a hot spot in current research

Commonly used cathode materials include lithium nickel-cobalt manganese oxide (ternary batteries) or lithium iron phosphate. The specific capacity and voltage platform of the former are relatively high, but their thermal stability is poor, there is a risk of oxygen release, and there are great safety hazards

Lithium iron phosphate structural stiffness, excellent thermal stability, no risk of oxygen release, safety performance is very prominent, has now exceeded the installed capacity of ternary batteries, with Tesla as the representative of many car companies choose lithium iron phosphate batteries, it is expected that in 2025 China's lithium iron phosphate installed capacity will account for 60%, and overseas will also reach 20%, it is expected that the global lithium iron phosphate medium and long-term penetration rate is expected to reach 35%

However, lithium iron phosphate has a relatively low energy density problem, the Ministry of Industry and Information Technology recently issued the "lithium-ion battery industry specification conditions (2021 version)", clearly requires energy battery energy density ≥ 180Wh / kg, which is a challenge for lithium iron phosphate batteries

Therefore, as an "upgraded version" of lithium iron phosphate, the new cathode material: lithium manganese iron phosphate (LMFP), has aroused widespread concern. It has the advantages of wide range of raw materials, low cost, high environmentally friendly theoretical specific capacity, stable discharge voltage, thermal stability and good circulation, especially the energy density is 10%-20% higher than that of lithium iron phosphate, which is expected to become a new generation of high energy density power battery cathode material potential materials

In addition, lithium ferromanganese phosphate and ternary material can be well composited, the resulting cathode material battery has both ternary high energy density, high power characteristics, but also has the advantages of high safety and low cost of lithium ferromanganese phosphate, and ultimately makes the performance of all aspects of the battery more balanced, making up for the gap in the market

At present, there are already German nano, Rieter Lithium Energy (Ningde times into the shares), Pengxin Resources, Dangsheng Technology and other enterprises in the layout of related technologies, and has been applied in light vehicles (two-wheeled electric vehicles), it is expected that in the next one or two years, lithium ferromanganese phosphate will achieve initial volume on passenger cars

Second, the mode of cooperation

This project benchmarks the technology of well-known enterprises, and welcomes enterprises with financial strength and industrial foundation to negotiate and purchase technology packages
