Teams from US, Japan, China, Canada find solutions to decades-old challenges
Scientists world over have been striving to develop safer, higher-capacity, and faster charging rechargeable batteries which can keep the volatile metallic structure in them intact. There are several challenges before these batteries can be widely used in practical applications.
The Japanese team from Tohoku University has come up with a solution by adding multivalent cations, such as calcium ions, that could fix the age-old issue of energy degradation. They were able to stabilize lithium or sodium depositions effectively by this process.
Close on the heels of this, a team of researchers led by chemists at the US Department of Energy’s (DOE) Brookhaven National Lab has learned that an electrolyte additive allows stable high-voltage cycling of nickel-rich layered cathodes, which may change the limits of…
