Samsung SDI Showcases New Manganese-iron Phosphate Lithium Battery
According to Business Korea, Samsung SDI demonstrated its latest lithium manganese iron phosphate (LMFP) battery technology for the first time at the IAA Mobility 2023 in Munich, Germany, marking the company's official entry into the lithium iron phosphate battery market.
Lithium iron phosphate battery and ternary battery are the two mainstream technologies of power battery at present. Manganese iron phosphate lithium battery adds manganese element based on lithium iron phosphate, and its energy density is 15%-20% higher than that of lithium iron phosphate battery, which makes up for the short board of lithium iron phosphate battery in terms of energy density. Therefore, it is an upgraded version of lithium iron phosphate battery.
In the past few years, Chinese companies have dominated the global lithium iron phosphate battery market, occupying most of the market. However, with the increasing demand for electric vehicles and the pursuit of low-cost, high-energy-density batteries, other battery manufacturers are also starting to focus on this area.
Samsung SDI used to produce high-nickel ternary batteries, but now they are actively exploring new lithium manganese iron phosphate battery technology, which will make their product line more diversified. Based on the traditional lithium iron phosphate battery, this new type of battery effectively increases the energy density by adding materials such as manganese to the positive electrode material. This enables the new battery to achieve an energy density increase of about 15-20% while keeping costs relatively stable.
The CEO of Samsung SDI has said that the company plans to focus on high-end batteries, offering cheap batteries in cobalt-free form rather than lithium iron phosphate batteries. However, the company's leaders have recently admitted that lithium iron phosphate batteries are still an important platform that cannot be ignored in the field of electric vehicles. To expand their business and meet customer needs, they are going all out to develop such battery technologies.
