According to foreign media reports, researchers from the University of Houston and Toyota Research Institute of America have discovered a very promisingHigh capacity lithium battery, its potential applications includeelectric car, battery storage for renewable energy systems, etc.

Joule journal stated that the battery is the first to operate with a limited electrolyte when using organic electrodes. Researchers say that by using a fluoride-free electrolyte, the battery can store and release more energy than early high-capacity lithium batteries. Much energy.

Yan Yao, associate professor of electrical and computer engineering at the University of Houston, said researchers could confirm that fluoride in commonly used electrolytes can cause battery performance to degrade.

Scientists have spent decades searching for high-energy magnesium batteries, hoping to take advantage of magnesium's natural advantages over lithium, the standardLithium-ion batteryelement used in lithium-ion batteries). However, magnesium is more common, therefore cheaper, and its internal structure is less susceptible to damage (which often causes lithium-ion batteries to explode and catch fire).

But magnesium batteries are only commercially competitive if they can store and release large amounts of energy. Yao said previously used cathode and electrolyte materials have been a stumbling block.

So far, the best cathode used in magnesium batteries is Chevrel phase molybdenum sulfide developed nearly 20 years ago, but its use in power andenergy storageIt cannot compete with lithium-ion batteries. But recent reports indicate that organic cathode materials can provide high storage capacity at room temperature, and the organic polymer cathodes tested provided higher voltages than Chevrel phase molybdenum sulfide.

Yao said future research will focus on further improving the battery's specific capacity and voltage to matchLithium batterycompete.
