Advanced Battery Solutions for Tough Outdoor Environments
Crafting reliable, high-performance batteries for outdoor environments
As the energy transition progresses, outdoor applications are shifting from fuel-powered to electric-driven solutions. In response to this trend, we together with a global leader in advanced battery systems is developing a reliable, high-performance battery designed for motive and stationary applications. This solution is tailored to withstand the harsh outdoor environments, ensuring robust, durability, safety, and efficient operation of outdoor power equipment.
Seeking materials for robust, safety, reliability and outdoor durability
Higher power density and faster charge-discharge cycles generate additional heat, presenting a key challenge to safety. In motive applications, especially the supplement of charged batteries, the system housing must withstand mechanical impacts during transportation, replacement, or assembly, requiring materials that offer both stiffness and resilience. Furthermore, outdoor environments, with factors such as UV exposure, extreme temperatures, and humidity, can gradually weaken housing strength and stiffness, impacting the durability and operational stability of the devices.

Balancing weatherabillity, safety, and durability
Our advanced polycarbonate is engineered to withstand the demanding environmental conditions, offering long-term toughness, reliability in operation, and preservation of housing structural integrity, which is essential to protect internal battery unit, circuit, etc., resulting in higher safety. The solution also delivers outstanding flame retardancy for higher safety against heat generated by power units during operation. Additionally, we offer materials with outstanding thermal conductivity aiding in effective heat dissipation, extending the lifespan of critical components. This ensures optimal device performance within designed parameters, supporting overall system longevity and reliability.
Driven by the increasing demand for energy storage and clean energy applications, batteries are rapidly evolving to deliver higher power density and voltage, opening up a broader range of possibilities. Covestro is making the best effort in offering ideal polycarbonate solutions that meet these demands, propelling the industry toward a circular future.
