The world needs more power, preferably in a form that’s clean and renewable. Our energy-storage strategies are currently shaped by lithium-ion batteries – at the cutting edge of such technology – but what can expect in years to come?
From first ever battery invention in 1800, by Volta; till the latest technology which allows us to charge up our smartphones; the progress in battery technology seems to be unbelievable. But did that happen in a single battery technology?
These cylindrical cells are used to make the battery units for the majority of modern laptops (except the ultra-slims). Such a battery will usually contain 3, 6, or 9 such cells—some go as far as 12 or 15 cells. Inside one of these batteries, the cells will generally be pink in external color and interconnected by tabs that have been spot-welded together.
The capacity has also been slowly improved. The laboratory has been able to make 18650 batteries with a capacity of more than 3500mAh, but the stability consistency is not good, and the mass production trend cannot be formed for the time being.
