Japan made high-capacity sodium perchlorate battery progress

Currently used in smart phones and laptops are lithium batteries, however, although the lithium battery capacity, but after prolonged use of the risk of fire.

A research team at Qualtec Japan focused its attention on sodium perchlorate, which has a very high solubility profile. CV measurements were carried out using saturated sodium perchlorate (SSPAS) to determine how much electrolysis took place at what voltage. The results showed that the electrochemical window reached 3.2 volts, showing good characteristics, ordinary lead-acid battery electrochemical window does not exceed 2 volts.

The above sodium perchlorate battery, the charge flow in the aqueous solution convenient, does not catch fire, and charging time only takes 2-3 minutes. At present, due to the smaller electrochemical window, there is still a problem of small capacity to be solved. Researchers believe the technology can be used in batteries for smartphones and electric vehicles.

This technical achievement opens up a new avenue for the development of high-capacity storage devices. Research report published in the British science magazine "SCIENTIFIC REPORTS" on.
