Long-Term Emergency Battery Mg:air │ Instant Power with Just Saltwater for Municipalities, Hospitals, and Factories
In times of disaster or sudden power outages, the most important safeguard is a reliable emergency power source. The magnesium-air battery “Mg:air,” developed by KEM (THAILAND) CO., LTD., offers instant electricity generation using only saltwater. With up to five years of shelf life, it's quickly becoming the new standard for emergency preparedness.
■ Saline Activation Enables 5-Year Storage
Mg:air is an air battery using saltwater (water + salt) as its electrolyte. Because no chemical reaction occurs during storage, there's no degradation. By simply adding saline when needed, it generates power instantly, even after years in storage. This makes it ideal for emergency stockpiles in government facilities and institutions.
■ One Smartphone Charge Capacity │ Lightweight & Safe
Designed to charge one smartphone, Mg:air balances output with safety. Weighing approximately 350g, it includes a USB output port to power LED lights and communication devices. Unlike fossil fuels or lithium batteries, Mg:air poses no risk of overheating or toxic gas emission, making it safe for indoor use.
■ Trusted by Key Sectors
