“Carbon Peaking • Carbon Neutrality” has become a global priority for all countries and industries, and the concept of green energy saving has also been widely recognized by the people. Thanks to the new infrastructure and ‘dual carbon’ goals, the lithium-ion battery industry has developed geometrically at an astonishing pace. Lithium-ion iron phosphate walks in the forefront for its safety and stability, and has constantly carried out security upgrades. By following the nuclear-grade safety design concept and leveraging its over 30 years of professional experience in the power field, we deeply applied power electronics to the lithium-ion battery technology and released lithium-ion battery solution with high safety and reliability - Smart Backup Lithium-ion Battery System Solution (Safety-Li, Smart-Li, Simple-Li).
