Tesla patents new cathode material that enhances LFP battery

Leading electric vehicle maker, Tesla, has patented a blended cathode material that enhances LFP batteries.

A tweet on 7th November says the patent WO2024229047A1 describes novel blended cathode active materials with Iron Phosphate based and minimal Nickel Oxide based materials, as well as the method for their manufacture.

It is expected to achieve superior battery performance and also significantly reduce the use of expensive elements for making LFP batteries.

Many benefits attached

The new patent comes with several benefits to the users. Among the top benefits is increased capacity retention, which means the batteries will serve users for longer periods after every charge.

They are also expected to last longer with a longer cycling lifespan. This means there will be more charge and discharge cycles completed before the battery finally grows weak.

Notably, one of the major challenges to car batteries is high temperatures. With the new patent, the batteries will also maintain a higher performance under high temperatures, which is a major improvement from the previous ones.

These batteries will also cost less, since the patented materials ensure minimal increase in material costs compared to standard LFP.

Invented by Jeffery R. DAHN, Chongyin YANG, Meng YUE, and Connor P. AIKEN, the patent was assigned to Tesla Inc and was first filed on 30 April 2024, and published on 7th November 2024.

Improving Tesla performance

Tesla has been improving the performance of its vehicles in several ways. Recently, it has been expanding the reach of its superchargers, reaching over 60,000 with a new station in Japan, so that Tesla owners can easily charge wherever they are at no extra cost.

With this new patent, the company will improve users’ experience by not only reducing the cost of high-quality batteries, but also making them last longer to serve users better.
