Chinese battery manufacturer CATL will begin supplying Tesla with its m3p stacks whose marketing will begin early next year, but are already mass-produced in their facilities. Information, which comes from the local environment Late shipmentindicates that they will be implemented in the units of the Tesla Model Y They have a battery of 72 kWh capacitywhich will be produced in Shanghai giga-factory early next year.
Although some doubts have been expressed as to the nature and composition of M3P batteries of CATL, it is finally a question PSMA batteries of lithium ferrophosphate to which manganese is added. By adding this new component to the well-known LFP formula, the working voltage of the cells and the energy density are increased without implying a significant increase in production costs, manganese being a particularly cheap material.
The material used in CATL’s M3P batteries will be supplied by Shenzhen Dynanonic Co, which announced plans to produce 110,000 tons of LMFP material in the second half of this year. In Tesla’s plans there is also the production of LMFP batteries, but its development cycle is much longer than that of CATL, so its strategy goes through obtain these batteries first from third-party suppliers.
After completing the tests with the samples sent by the Chinese manufacturer, Tesla will take about three months to conclude the terms of the agreement, execute the contract for the acquisition of the batteries and start production of the vehicles with them already implemented.
Batteries are usually named after the materials that make up the cathode. LMFP cathode materials can be made by adding manganese to LFP cathode materials that are currently used to make LMFP batteries. It is also possible to dope LMFO materials with aluminum or magnesium to create the cathode. In the case of M3P batteries, lithium ternary materials and LMFP materials are added to the cathode, a solution that solves the problem of short life and high internal resistance of LMFP batteries according to information from LatePost.
M3P batteries use the olivine structure of LFP as the basic network structure. By doping two of the metallic elements, magnesium, zinc and aluminum replace iron in some places, explains a research note from Shengang Titles published at the end of last month. This design generates a phosphate of ternary materials that improves charging and discharging capacity and stability of charging and discharging cycles.
CATL Vice President and Research Director Wu Kai assured at a press conference that the new M3P batteries are already in mass production at its facilities and will be available for sale for from next year. According to Wu, these batteries are intended for electric cars that require autonomy of more than 700 kilometers (in the NEDC cycle).
