This curious battery is capable of storing six times more charge than conventional ones, according to its creators

Get batteries to last longer. That is one of the great objectives of current research in this area. There have been great advances in this field and now an international team of researchers led by Stanford University claim to have developed a battery that, in their own words, " can store up to six times more charge than those currently on the market ."

The research was published on August 25 in the journal Nature and it details the operation of alkali metal-chlorine batteries. These are based on the chemical conversion of sodium chloride (NaCl2) or lithium chloride (LiCl2) to chlorine.

For now it is just a prototype

Batteries

According to the researchers, the discovery of this type of battery was "fortuitous." They claim that " chlorine is too reactive and difficult to convert back to chloride with high efficiency" and that "in the few cases where others have achieved a certain degree of rechargeable, the performance of the battery has been poor."

The researchers' idea was not to create a NaCl2 or LiCl2 battery, but rather existing batteries using thionyl chloride (SOCl2). However, in one of their experiments with chlorine and sodium chloride, they found that "the conversion of one chemical into another had stabilized in some way, leading to some recharging capacity ."

The big breakthrough came when they formed the electrode using a porous carbon material developed by researchers at the University of Taiwan. The structure of this material is similar to a nanosphere with many very small pores. These hollow spheres act like sponges, absorbing large amounts of chlorine molecules and storing them for later conversion to salt within the micropores.

As the researchers explain, "the chlorine molecule is trapped and protected in the tiny pores of the carbon nanospheres when the battery is charged [...] Then, when the battery needs to be drained or discharged, we can discharge the battery and converting the chlorine to make NaCl [conventional salt] and repeating this process for many cycles . Currently we can cycle up to 200 times and there is still room for improvement. "

Researchers claim that its battery has a capacity of 1,200 mAh per gram

This very interesting process results in a higher energy density. While current lithium-ion batteries have a capacity of 200 mAh per gram, the prototype developed by these researchers has 1,200 mAh per gram , six times more.

At the moment, this battery is nothing more than a prototype that would be suitable for small appliances or devices, such as a remote control or headphones. However, the researchers hope that their batteries can be used in the future in devices where charging cannot be frequent, such as satellites or remote sensors.
