Tesla Reduces Distance Between Nickel and LFP Battery Technology Through Groundbreaking Cell Innovation
Tesla Introduces Updated Nickel-Based Battery Cell, Narrowing the Gap with LFP
Tesla has announced the development of an updated nickel-based battery cell, a move that could significantly improve the long-distance performance of vehicles relying on nickel-based packs. The cobalt-free NMC640 type of battery cell, developed through Tesla-funded research, is set to offer a lifespan comparable to that of lithium iron phosphate (LFP) cells at higher daily charge limits.
The new battery cell technology is prized for its higher energy density, a trait that translates into longer driving ranges and stronger performance. This is a marked improvement over LFP batteries, which, while more durable, suffer from lower energy density, resulting in slightly less range for a pack of comparable size.
Lars Moravy, Vice President of Vehicle Engineering at Tesla, revealed the details of the updated battery cell in a recent interview. The development of the updated battery cell is expected to have far-reaching effects across Tesla's product range.
The new cells may reduce the charging habits restrictions for prospective customers weighing the choice between LFP-equipped entry models and nickel-based long-range versions. With the updated battery cell, owners can now raise their daily charging limit to 90%, a significant increase from the traditional 80% limit advised by Tesla to avoid premature capacity loss.
The new chemistry of the updated battery cell enables a closer gap to LFP batteries. Tesla claims that the development of the updated battery cell "closes the gap to lithium iron phosphate (LFP) by half." This narrows the gap between nickel-based batteries and LFP batteries, a development that reflects Tesla's ongoing effort to improve the balance between range, performance, and durability.
Lithium iron phosphate (LFP) batteries are increasingly popular in the industry due to their more durable chemistry that is less prone to degradation from high states of charge compared to nickel-based batteries. However, the improved battery cell technology may make the long-distance performance of nickel-based battery vehicles more attractive to buyers.
Tesla has not specified when the new cells will begin appearing in vehicles. The announcement of the new cells reflects Tesla's ongoing commitment to innovation and improvement in battery technology. As the automotive industry continues to evolve, it will be interesting to see how this development impacts the market and consumer choices.
