Company Vision

With the widespread adoption of renewable energy and advancements in energy storage technology, IONTREE focuses on steady, long-term development and optimizes energy storage efficiency to support renewable energy goals and ensure grid stability and flexibility.

We understand that the safety of batteries is crucial for energy storage systems. Therefore, we utilize the safer "lithium iron phosphate" (LiFePO4) batteries, along with certified management systems. These batteries undergo rigorous dielectric and pressure resistance tests, ensuring stability even under high voltage conditions, and significantly enhancing the safety of the battery system.

Through the application of innovative energy storage technology, IONTREE, and its management team aspire to become active contributors to Taiwan's power grid, paving the way for the next generation to achieve a clean, green, and net-zero carbon emission energy landscape.
