Technology / product information

During natural disasters or blackout events, a reliable power source is critical. The magnesium-air battery "Mg:air," developed by KEM (THAILAND) CO., LTD., delivers instant electricity with a simple saltwater injection. With no maintenance required and a long shelf life, it is increasingly trusted for emergency use across Thailand.

■ Reliable Power with Just Saltwater
Mg:air is an air battery using magnesium as the anode and atmospheric oxygen as the cathode. When a specially diluted saltwater solution is injected, it activates and generates power. Note: Plain drinking water lacks sufficient electrolytes and may cause failure—proper saltwater is essential for activation.

■ Maintenance-Free and 5-Year Storage
Mg:air remains inert until saltwater is added, allowing up to 5 years of maintenance-free storage. This feature ensures that emergency power is available instantly, without regular checks or upkeep. It’s the ideal solution for emergency kits, shelters, and preparedness stockpiles.

■ Designed for Thai Market Needs
In Thailand, blackouts caused by floods or lightning are common. Mg:air provides a fuel-free, instantly deployable solution suited to these conditions. Its intuitive operation and safety features make it perfect for use at home, in hospitals, evacuation centers, and other critical facilities.

■ Why Mg:air is the Preferred Emergency Power Source
- Activates instantly with saltwater
