Contrary to recent news reports of solar-powered smart watches, Apple has confirmed that it will stick with lithium-ion batteries for its upcoming iWatch. These batteries are to be supplied mainly by Samsung SDI, LG Chem and Tianjin Lishen Battery, according to industry sources./i]
"Apple will utilize LG Chem’s stepped battery since it offers better longevity than others and can be applied for different shapes," a source said.
Layers of batteries are used to form 'stepped batteries' resulting in 16% more energy efficiency. The step design minimizes wasted space in the battery pack.
The site's source discredits the use of solar power as being possible for supplemental power at best.
“Since the energy efficiency of solar-charging technology is one-tenth of the lithium-ion battery, it doesn’t make sense to run a gadget with solar power,” he said.
Both LG Chem and Samsung SDI declined to comment on the matter.
