Rumours are starting to circulate that Samsung is thinking of ditching lithium-ion batteries to power its phones.

The move comes following the disastrous launch of Samsung’s Galaxy Note 7 in 2016 that saw it lose what analysts estimate are hundreds of millions of dollars after fires in the handsets caused a recall.

According to a comprehensive investigation revealed the battery design of the Galaxy Note 7 was at fault for the ordeal.

Now there are suggestions that Samsung will use graphene cells instead and mass production could start as early as next year.  Graphene is a form of carbon that can be used to develop smaller, slimmer batteries but with higher capacity.

There is a need for higher-capacity batteries that last longer, are quicker to charge and aren’t as dangerous in cases of catastrophic failures.

Graphene has been touted as the next big thing in the smartphone industry for more than half a decade now but has yet to be commercialised in the form of a mobile battery.

They would be expensive to produce at first which could push up the price of mobile handsets.

Late last year Samsung won a patent on a solution that would allow it to improve existing lithium-ion batteries by adding a graphene component to the process of manufacturing those traditional cells, claiming the end result of such a production approach could be cells that charge up to five times as fast as existing modules.

Huawei and Tesla are some other high-profile names that have been exploring the concept of consumer-grade graphene batteries in recent years.

Samsung’s tech institute previously claimed a graphene mobile battery can be fully recharged in approximately 12 minutes and have around 45% higher capacity than a lithium-ion cell of a comparable size.

However, the high production costs of graphene batteries will probably keep such solutions away from Samsung’s mainstream smartphones planned to be released in 2019.

* Lithium-ion battery fires can be particularly dangerous on aircraft which is why more than 50 airline companies across the world – including some of the biggest and best-known - now carry AvSax fire containment bags to deal with fires in personal electronic devices caused by lithium-ion batteries that power them.

The bag – which won the Queen’s Award for Enterprise this year - has been used 27 times to deal with emergencies since the start of 2017.
