SK On, the battery subsidiary of SK Innovation, today announced that its cobalt-free battery won a bronze award in the Smart Transportation category at the prestigious Edison Awards 2024 on April 18.


The latest award not only demonstrates SK On’s technological prowess, but also underlines the company’s commitment to ethical innovation and sustainable progress in the green energy sector.


SK On’s cobalt-free battery is considered a breakthrough in EV battery technologies, overcoming technological barriers in cobalt-free cathode material compositions.


Removing cobalt from traditional NCM cathode material compositions can limit a battery’s lifespan due to structural instability. SK On solved this challenge of lifetime degradation by using its proprietary technologies, specifically focused on monocrystalline cathodes and doping. Furthermore, the company has successfully addressed the issue of energy density in cobalt-free batteries by leveraging its unique high-voltage cell design solutions.


The importance of SK On’s cobalt-free battery goes beyond technological advancements, as it also represents a crucial step toward advancing sustainable energy and transportation.


Cobalt, known for its high cost due to limited availability, is often associated with ethical concerns associated with its extraction. In an effort to reduce dependence on cobalt and adhere to ethical and environmentally responsible practices, SK On began developing a cobalt-free battery. The company successfully developed the battery more than a year ahead of the target date.


The bronze award marks the second consecutive year that SK On has been recognized at the Edison Awards. In 2023, SK On’s NCM9 battery made history by winning the bronze award, making SK On the first global battery manufacturer to receive such an honor.


“We are pleased to have received a bronze award for our cobalt-free battery at the prestigious Edison Awards 2024,” said Kim Sang-jin, Head of Platform Research at SK On. “This achievement underlines our commitment to pushing the boundaries of innovation while prioritizing environmental sustainability. SK On will continue to develop battery technologies that promote a positive impact on the environment and society.”
