The scientist had derived a new fast-charging battery technic in the US. They had claimed a technological breakthrough that could resolve the problem of charging time taken by the charging station for all-electric vehicles. Writing in the journal Joule, researchers at The Pennsylvania State University said that such a speedy charge rate required a battery to rapidly take in 400 kilowatts of energy.
Current generation vehicles are not capable of this feat as it risks the lithium plating, the formation of metallic lithium around the anode, which would severely deteriorate battery life. To get around this constraint, the researchers raised the temperature of their experimental battery to 60 degrees Celsius during the charge cycle, then lowered it back down as it was used.
What this does is “limit the battery’s exposure to the elevated charge temperature, thus generating a very long cycle life,” said senior author and a mechanical engineer at The Pennsylvania State University.
But scaling up the design and accepting it in the market may take a decade because the technic is derived now and would take time to settle, said by a member of the American Chemical Society told AFP. Makers will need to make sure that rapidly raising the temperature is safe and stable, and doesn’t lead to explosions given the phenomenal amount of energy that is being transferred.
“Fast-charging battery is one of the holy grails of electric vehicles,” he said. “It’s one of the things that is necessary for them to compete with petroleum-fueled internal combustion engines.
“Current generation Tesla vehicles require about 30 minutes for a partial charge.
In conclusion, if the great technology accepted then we would find the charging in an easier way.[wp-reviews]
