Electronics giant NEC has shown off a new technology for lithium-ion batteries which it claims could boost the devices' lifespans to around thirteen years or more.
The company has announced today a lithium-ion battery development which improves the durability thanks to a revision of the electrolytic formula combined with a switch from cobalt to manganese for the electrode.
The result, the company claims, is a lithium-ion battery which can be charged and discharged more than 20,000 times - doubling the capabilities of current lithium-ion batteries.
There's some bad news to be had, however: while NEC is best known for its consumer electronics products, it's unlikely to be working on the technology for laptop or smartphone use - at least initially.
Earlier this year the company announced a deal with Nissan to develop durable batteries for electric vehicle use, and it's likely for this that the new technology has been primarily developed.
It's also going to take a while before the devices hit the market: automotive expert Paul Tan reports that NEC is targeting a twenty-year durability for the new batteries, and predicts that the technology won't be market-ready for around five years.
