New phone battery fully charges in 1 minute

A new breed of phone battery that could fully recharge in as little as one minute is now in the works, a tech site reported.

 

The new battery developed by Stanford University researchers uses aluminum ion cells and is potentially safer than the present-generation lithium ion cells, PC World reported.

 

“Our new battery won’t catch fire, even if you drill through it,” it quoted Stanford chemistry professor Dai Hongjie as saying.

 

Also, it noted aluminum-ion cells cost much less than lithium-ion and are not liable to explode or burst into flames when damaged.

 

Dai added they "accidentally" discovered that a simple solution is to use graphite, coming up with a battery that can endure 7,500 charging cycles.

 

Present prototype aluminum ion batteries can last much fewer cycles, while lithium ion batteries can last only 1,000 cycles.

 

Prototype

 

Dai’s team used an aluminum anode with a graphite cathode along with an ionic liquid electrolyte. The battery is also potentially flexible.

 

However, the present prototype's output is a paltry two volts, less than the 3.6 volts from present lithium-ion batteries.

 

It also has an energy density of 40 watts per kilogram, much less than the 100 and 260 watts per kilogram for lithium ion. — Joel Locsin/TJD, GMA News
