It will not sink: scientists have created a concept of a military submarine on a lithium-ion battery

Naval Group engineers are convinced that such a battery is safer and energy efficient. Lead-acid batteries (LABs), which are equipped with modern military submarines, pose a risk to safety, starting with their production and ending with operation. Lithium-ion batteries (LIB) could be replaced because they are more energy-intensive, which will give submarines more autonomy, writes navalnews. com.

Lithium-ion batteries, in addition, are more convenient to charge-this is possible even when the boat is in the water. But to charge the LAB completely, you need to be near the shore. There is another plus-lithium-ion devices do not reduce the level of energy that is given, as you discharge, which will provide great tactical mobility, the material is said. The French company Naval Group has been exploring the potential of Lib for 16 years.

Recently, scientists have stated that they managed to develop a lithium-ion battery that could nourish the electronics of a submarine vessel. Engineers realized that there were also a number of problems here that the device should not pose a danger to crew and equipment. So, first of all, they made the batteries as stable as possible and protested it in different extreme conditions, such as pressure, increase or decrease in temperature, etc.

Then they invented a design that could reduce the risk of smoke and/or ignition. As a result, the design turned out to be multi -level, consisting of several layers, each of which protects the previous one. Two years ago, the Naval Group prototype was tested on the "coastal object". Testing on the submarine has not yet been conducted. So far, engineers are engaged in the development of architecture of the submarine electrical network and charging systems.
