Put some manganese in it! Lithium manganese iron phosphate with 80% manganese content is here!

Lithium iron manganese phosphate (LMFP), which is considered as one of the important upgrading directions of cathode materials, has made a new breakthrough.

On October 11th, British startup integrations Power announced a breakthrough in the research and development of lithium iron manganese phosphate (LMFP), that is, the manganese content in the material increased to 80%, the specific capacity reached 150 mAh/g, and the working voltage was 4.1. Why did Integrations Power say this is a breakthrough? First of all, manganese content should be ≥ 50% to increase energy density. At present, the manganese content of lithium iron manganese phosphate material on the market is between 50-70%; Secondly, the voltage of Ferrous lithium phosphate material is 3.45 v, while the LMFP voltage of Integrals Power is 4.1 v, which greatly increases the energy density.

Although this is still in the research stage, Integrals Power said that this progress could increase the cruising range of electric vehicles by up to 20%, or reduce the size and weight of the battery pack while maintaining the same cruising range.

Integrals Power also said that third-party test in button cells has been completed and will soon be available for battery suppliers, battery manufacturers and original equipment manufacturers to evaluate and benchmark. 

It's also worth noting that Integrals Power produces these high-performance LMFP materials, as well as its proprietary LFP chemistry. According to the report, the plant's raw materials are sourced from European and North American suppliers, providing a competitive alternative to the Chinese-made cathode materials that dominate the global market.

This is an important development for foreign companies and domestic companies that are 'showing LMFP "their products. 

After several years of dedicated research and development, Ruipur Lancaster's lithium manganese iron phosphate battery cells have finally made their official debut.

On October 14th, local time, at the 90th Paris Auto Show, Ruipur Lancaster launched the LMFP battery technology in the world, and showed the GREEN CTP battery pack and GREEN BANK plug-in hybrid battery pack to customers around the world.

It is reported that the LMFP batteries introduced by Ripley-Lanjun combines the advantages of LFP batteries and NCM batteries, and superimposes the original Wen Ding technology, which has been further improved in terms of energy density, cycle life, low temperature performance, fast charging performance and safety performance. In terms of energy density, with the support of Wen Ding technology, the redundancy of the battery tabs has been 'cleared ",and the overall internal space utilization rate has increased by 3-5%. The improvement of micro solid-liquid interface has increased the lithium ion transmittance by 30%, and the volume energy density of the battery is as high as 430-520 Wh/L, which can increase the cruising range of a pure electric passenger car to over 700 kilometers. Mileage can reach 700 kilometers or more. In terms of safety, through the iterative upgrading of materials and electrochemical systems, the impedance of Riparian's LMFP cells has been reduced by 16%, which reduces the generation of excess heat in the cells and allows them to pass the pin-prick test again without heat spreading. In terms of low-temperature performance, the advanced double-height pole design can increase the lithium ion transfer rate in and between the poles by 30% through the improvement of the microscopic solid-liquid interface, ensuring that the capacity retention rate can still reach more than 80% at -30℃. In the aspect of fast charging ability, the LMFP voltage platform is close to ternary batteries, which improves charging efficiency and can realize the fast charging ability of 10-80% SOC in less than 18 minutes.

' lithium manganese iron phosphate is formed by combining lithium iron phosphate and lithium manganese phosphate, fully combining the advantages of both, with an olivine-type structure; Lithium manganese phosphate has the advantages of high voltage platform and high energy density, which makes up for the shortcomings of lithium iron phosphate; Because the radii of iron and manganese atoms are similar, mutual solubility in any proportion can be achieved, which makes it possible to produce lithium iron manganese phosphate. Shi, director of Longpan Science and Technology Research Institute, said in an interview. 

Compared with ternary materials, lithium iron manganese phosphate is more stable, avoiding the use of noble metals such as nickel and cobalt, and significantly reducing costs. GAC EAN battery R&D director Li Jin has said publicly at the industry conference: for new energy power battery technology route, compared with the lithium iron phosphate system, lithium manganese iron phosphate and spinel nickel manganese oxide and other high manganese cathode system platform voltage is high, high energy density, lithium consumption per unit of power is lower, the theoretical cost is lower, the future is expected to replace part of the lithium iron phosphate battery. Therefore, lithium iron manganese phosphate is a highly anticipated project by material companies and battery companies, and even considered as a highly feasible transition scheme to solid-state batteries.

At present, both power battery companies, upstream material manufacturers and vehicle manufacturers are 'rushing to the beach'. Especially since last year, 'accelerated operation ",the layout and production of industrial chain enterprises continued to accelerate, and this year gradually entered the application redemption period.

In addition, more crucially, some people in the industry believe that "only the pure utilization of lithium ferrous phosphate can be realized (that is whether manganese as a single negative electrode material can better meet the requirements of automotive power and large-scale energy storage products on a large scale '.
