[Asia Economy Yang Nak-gyu, Military Specialist Reporter]A technology that can double the capacity of thermoelectric batteries used in guided weapons has been developed for the first time in Korea.
According to the Agency for Defense Development (ADD) on the 29th, thermoelectric batteries used in guided weapons are special batteries that operate under high temperatures of around 500℃ and heavy loads. Applying the newly developed technology can simultaneously solve the long manufacturing time, high cost, and capacity limitations, which have been considered drawbacks of existing thermoelectric batteries.
The world's first developed '3D structured high-performance anode technology' (lithium-impregnated metal foam anode) maintains the shape of the electrode well even under heavy loads without the molten lithium (melting point 180℃) flowing down during operation at high temperatures.
The developed technology can also be applied to high-energy density electrodes, which are core components of batteries in civilian sectors, making it widely applicable to lithium batteries for portable electronic devices and electric vehicles.
ADD added that, based on the technological capabilities secured in the field of high-energy density electrodes, it continues to focus on developing the world's highest performance batteries for guided weapons and torpedoes.
This research was conducted by ADD's Principal Researcher Choi Yoo-song and Senior Researcher Ahn Tae-young, and the results were published in the online edition of the scientific journal 'Scientific Reports.'
