The news powder coatings from Jotun will improve electrical insulation, thermal management, fire, and corrosion protection of batteries used in electric vehicles.
The paints and coatings supplier Jotun has launched a new range of powder coatings technologies designed to improve the safety, durability and efficiency of battery systems used in electric vehicles (EVs) and energy storage systems (ESS). The move comes as global investment in electrification continues to surge, driving demand for high-performance battery solutions.
The shift towards cleaner transport and energy has been accelerated by increasingly strict climate regulations, particularly those targeting road emissions, which account for approximately 15% of global carbon output. As a result, the market for EVs has grown rapidly. According to the International Energy Agency’s Global EV Outlook 2023, annual EV sales are forecast to exceed 40 million units by 2030, with battery manufacturing capacity reaching 4548 GWh.
China currently leads the world in both EV and lithium-ion battery production and is targeting EVs to represent 25% of all road traffic by 2030. Meanwhile, the US and Europe are ramping up investments in electrification, and rising demand for renewable energy—solar, wind and hydro—has bolstered the need for efficient ESS installations.
“Our teams in China worked closely with major battery manufacturers to develop powder coatings tailored to their most pressing challenges. We focused on improving electrical insulation, thermal management, fire and corrosion protection—key factors in boosting battery life, safety and overall efficiency,” has stated Mehmet Ali Kamacıoğlu, Global Sales & Marketing Director for Powder Coatings at Jotun.
Jotun’s EV Battery Solutions, introduced in 2025, comprise a portfolio of powder coatings designed to protect and insulate critical battery components. These coatings help mitigate thermal runaway—a phenomenon where high temperatures can destabilise a battery’s structure, posing fire or explosion risks.
“Without proper insulation, batteries can become extremely hazardous. They’re also prone to corrosion, which compromises safety and performance. While manufacturers have traditionally relied on plastic materials and liquid coatings, these tend to be complex, costly and less stable,” has added Mehmet Ali Kamacıoğlu.
Beyond safety, battery longevity remains a major concern for original equipment manufacturers (OEMs). EV batteries face harsh conditions, from road vibrations to exposure to salt, moisture and chemicals. Jotun’s powder coatings provide a robust layer of protection for various high-voltage battery pack components, engineered to endure thousands of charge-discharge cycles across a range of environmental conditions.
“Our systems offer more reliable insulation and corrosion resistance, while maintaining the integrity of the electrical circuit. And as battery production ramps up, efficiency and sustainability are top of mind. The right coatings system reduces manufacturing complexity and downtime. Plus, as solvent-free solutions, powder coatings support compliance with environmental regulations on volatile organic compounds (VOCs),” has concluded Mehmet Ali Kamacıoğlu.
