6F22 carbon battery.Underwater drone batteries can extend battery life by drinking seawater

　　Nowadays, drones are very popular, and underwater drones are even more useful. Exploring the ocean, searching for fish, and taking photos by divers all rely on the help of underwater drones. However, underwater drones also have some drawbacks, such as the limited distance they can shoot with each charge. Therefore, Open Water Power, a startup funded by Massachusetts Institute of Technology, has developed a battery that can convert electricity from seawater, extending the working distance of underwater drones by ten times!

　　Underwater drones typically use lithium batteries, but this type of battery can cause some problems. For example, this type of battery may cause a fire, so airplanes generally do not transport lithium batteries and are transported by large ships. The R&D team of Open Water Power has developed a better battery. The company has previously developed car engines that use air as an oxidant for chemical reactions, but now they need to use seawater to power underwater drones.

　　Ian Salmon McKay from Open Water Power stated that the newly developed battery can "drink" seawater while discharging waste. Compared to the onshore engine's discharge method, the technology's discharge method does not cause much damage to the environment.

　　The new battery consists of an aluminum alloy anode, a nickel alloy cathode, and an alkaline electrolyte inside. After seawater enters the battery, the cathode decomposes it into hydroxide anions and hydrogen gas, which then react with the aluminum anode to generate aluminum hydroxide and release electrons for power supply.

　　The research and development team stated that the new battery provides ten times more power than regular lithium batteries and is safer and more durable to use. However, the new battery can only maintain its power through the above principles when submerged in water, and researchers have found that the aluminum anode is more prone to corrosion, but users can replace it at a low price.

　　This new battery has a wide range of uses. The US Navy has partnered with Open Water Power to apply this battery in acoustic sensors for detecting enemy submarines. In addition, this summer, Open Water Power will also collaborate with a company called Riptide Automotive Solutions, which has an existing underwater drone that can operate 185 kilometers on a single charge. Through this collaboration, it hopes to extend the drone's working distance to 1852 kilometers.

　　These collaborations are just the tip of the iceberg, and the new Open Water Power battery can be used anywhere we want to work underwater. For example, new batteries can dive deep into the sea to draw sea level or disaster maps; Can be used for long-distance oil exploration; It can also be used to search for wreckage of crashed planes.
