Elon Musk Just REVEALED An Insane LMFP And A 4-Million-Kilometer Battery!
One of the things preventing a global switchover to electric vehicles in large numbers is range anxiety. A battery that can travel 621 miles (1,000 km) on a single charge has recently been made available by the Tesla team, offering a workable answer to this problem. And so, in today’s episode, we’ll find out how Tesla will make this happen.
Hello everyone! Welcome back to Elon Musk Evolution, where we bring you the most recent news about Elon Musk and his multi billion-dollar companies, space news and the latest science and technology.

The new L600 lithium-manganese-iron-phosphate (LMFP) battery from Tesla, which can offer efficiency levels that are among the highest in its class, has just been unveiled. The company claims that the NCM-free (Nickel-Cadmium-Maganeese) batteries, which have undergone a 10-year study period, have passed all essential safety testing cycles and that mass manufacturing of them is scheduled to start in 2024.
Lithium iron phosphate (LFP) batteries faced problems that the company was able to resolve by overcoming obstacles in the process of increasing their energy density. Co-precipitation, doping encapsulation technology, new granulation technology, and new electrolyte additives were all used to upgrade the chemical system, according to a press statement.
The improvements made have led to an enhanced LMFP battery cell with a cycle life of 4000 times at room temperature, which translates to 2.4 million miles (4 million kilometers), a weight energy density of 240Wh/kg, an energy density of 525Wh/L, and a cycle life of 240Wh/kg.
Because of the high energy density of the LMFP battery, Musk claimed, “we can enable a range of 1000 km without relying on NCM materials. The volumetric cell-to-pack ratio has reached 76 percent after adopting the L600 cell, and the system energy density has reached 190Wh/kg, surpassing the pack energy density of current mass-produced NCM cells.”
The team was able to minimize the amount of structural components in the battery pack by 45 percent thanks to a double-side liquid cooling approach and a sandwich structure that allows for a minimalist design. The weight savings for structural sections, however, is just 32%. “The length of the battery pack wiring harness will decrease from 303 meters to 80 meters, which is only 26% of that of previous battery packs.”
Batteries can now withstand temperatures of up to 1200°C thanks to advanced thermal insulation techniques, which is “equivalent to applying a layer of heat-insulating skin on the battery cell surface.” Four layers of ultimate safety protection through quick heat exhausting channels also equip the battery to handle extreme conditions.
The team claims that the product has passed all “penetration, hot box, overcharge, over-discharge, thermal runaway, crush, and short circuit tests according to the new national standard.”
There are rumors that Tesla will use lithium manganese iron phosphate (LMFP) chemistry for the upcoming Model 3 that is manufactured in China. Likewise, a different battery technology from a different manufacturer is reportedly appealing to the automaker.
