An Alternative Way to Eat a Bacon Sandwich

If Lithium-Sulfur Batteries were nuclear fission in the battery field, then Lithium-Air Batteries were the equivalent of nuclear fusion. The idea of obtaining oxidants from the surrounding air essentially represented the upper limit of energy density for all batteries using lithium metal as the anode material.

Compared with conventional lithium-ion batteries, Lithium-Sulfur Batteries had an energy density an order of magnitude higher. Compared with Lithium-Sulfur Batteries, Lithium-Air Batteries likewise had an energy density an order of magnitude higher, both in terms of volumetric energy density and gravimetric energy density.

Their only drawback was probably that they were not particularly suitable for devices such as mobile phones or artificial satellites.

After all, Lithium-Air Batteries had such high energy density largely because their oxidants were not contained within the battery itself, but outside it. They needed to "breathe."

Mobile phones were often kept in pockets, while artificial satellites were far removed from the atmosphere. It was difficult for such devices to take advantage of Lithium-Air Batteries. However, for new-energy vehicles or small fixed-wing drones, there was practically no more suitable power source.

For that very reason, Lithium-Air Batteries had even stricter technical requirements than Lithium-Sulfur Batteries.

Not only did they face the lithium dendrite problem common to all Lithium-Anode Batteries, but Lithium-Air Batteries also imposed extraordinarily demanding requirements on materials. Lithium itself was an extremely reactive metal. Exposing it to the atmosphere while ensuring that it reacted only with oxygen in the air was obviously no simple task.

That was not even counting the series of complex side reactions.

The key to solving this problem was finding a membrane capable of filtering out water vapor, carbon dioxide, and other gases from the air while precisely and rapidly selecting oxygen molecules.

In fact, this technology existed on Wreckage One.

Unfortunately, Wreckage One had
