Tesla launches Megapack XL using LFP batteries, with 50% more power

Tesla has released a new Megapack XL, which is 50% more powerful than the previous one. In addition, the new battery is large and powered by LFP batteries, which is the next step in the development of the company’s energy business.

Tesla offers a wide range of services and products aimed at accelerating the global transition to sustainable energy. One of the company’s most important products in this regard is Megapack, an energy storage system designed to stabilize the power grid and reduce reliance on fossil fuels. To expand the impact of this product, Tesla began construction of the Lathrop Megafactory in September 2021 and has big plans for the facility. Additionally, the company updated its Megapack to increase its value to the industry. Reddit user u/space_s3x (via Tesla North) noticed that Tesla has quietly made changes to the Megapack’s specs on their website and they are very impressive. Above all, its capacity has been increased by nearly 50%, from 2.6 MWh to 3.9 MWh. The Megapack itself has become 64% heavier (33,000 lbs) and taller: 6 feet longer (27%), 2 inches wider (3%) and 1 foot taller (17%).

These changes indicate that Tesla has started using LFP battery cells, which are likely made by CATL, according to earlier rumors, which should have significantly reduced the cost of production. In early 2021, Tesla CEO Elon Musk revealed that the company was considering switching to cobalt-free lithium iron phosphate (LFP) batteries in its stationary energy storage products. He explained that the essential and the cost of the cell is in the cathode. For high-energy cells, such as those the company uses in most of the cars it produces, nickel-based lithium-ion cells are used. They have a higher energy density and longer range than iron-based cells. However, for stationary storage, the energy density is not so important because it just stays on the ground. That’s why the vast majority of stationary storage facilities produced by the company will technically be iron-based lithium-ion cells with an iron phosphate cathode. In fact, the phosphate part isn’t necessary and it’s just iron or nickel, Musk explained.

“However, stationary storage, the energy density is not as important because it just stays on the ground and so I think the vast majority of stationary storage will technically be iron-based lithium-ion cells with a cathode at the iron phosphate. But the phosphate part is unnecessary. It’s really just the iron or the nickel. The exclusion of the controversial cobalt makes the production not only more affordable from a financial point of view, but also more acceptable from a moral point of view. Another factor is that the availability of these materials is relatively low, while iron is a very common material. Thus, the production of energy storage devices using cobalt-free lithium-iron-phosphate batteries will solve a number of serious problems and lead to a high quality, cheaper and undisputed product.
