Tesla Battery Technology

Tesla’s battery technology has been a game changer in the automotive industry, revolutionizing electric vehicles (EVs) and energy storage systems. The company’s cutting-edge innovations have not only improved the overall performance of EVs, but have also significantly reduced their costs, making them more accessible to consumers.

One recent development in Tesla’s battery journey is its collaboration with Magnis Energy Technologies, an Australian company specializing in producing high-quality lithium-ion batteries. In this article, we will take an in-depth look at Tesla’s battery technology and explore the partnership between Tesla and Magnis Energy Technologies.

Tesla’s Battery Technology: The Core Elements

  1. Battery Chemistry

Tesla’s battery packs are composed of lithium-ion cells, known for their high energy density, long cycle life, and relatively low self-discharge rate. Tesla has primarily used Nickel Cobalt Aluminum (NCA) chemistry in its cells, but with the introduction of the 4680 battery cell, they shifted to a high-nickel and low-cobalt chemistry.

This new composition reduces cobalt dependency, an expensive and ethically concerning material, and further improve energy density and longevity.

  1. Battery Cell Design

Tesla has consistently innovated its battery cell designs to optimize performance and reduce costs. The most recent development is the 4680 cell, named for its dimensions (46mm diameter and 80mm height). This larger format, compared to the previous 2170 cells, increases energy density and thermal performance while reducing manufacturing complexity.

The tabless design enhances the cell’s electrical conductivity and heat dissipation, contributing to a more efficient and longer-lasting battery.


  1. Battery Pack Architecture

Tesla’s battery packs are designed to provide structural support and crash protection while optimizing energy storage and thermal management. The company employs a modular approach, assembling cells into modules and then modules into packs. Tesla’s innovative cooling system uses a combination of liquid and passive cooling to maintain optimal temperatures within the pack, ensuring consistent performance and prolonging battery life.


Tesla’s Deal with Magnis Energy Technologies

In the quest for improved battery technology, Tesla has forged strategic partnerships with key players in the lithium-ion battery market. One such collaboration is with Magnis Energy Technologies, an Australian company focused on producing high-quality lithium-ion batteries and developing sustainable, environmentally friendly extraction methods for raw materials.

This partnership seeks to leverage Magnis’ expertise in producing high-purity graphite, a key component in lithium-ion battery anodes. The collaboration will enable Tesla to secure a reliable supply of high-quality graphite, essential for manufacturing more efficient and long-lasting batteries. Additionally, Magnis is developing new anode technologies that could further improve the performance of Tesla’s batteries.

In return, Tesla will provide Magnis with technical assistance, helping the company enhance its battery production capabilities. This collaboration will be mutually beneficial, allowing Tesla to access a stable supply of critical materials while supporting Magnis in expanding its battery manufacturing capacity.
