India, April 11 -- Our smartphones have shipped with lithium-ion batteries for the longest time-be it the Nokia 3310 or the latest iPhone 16 Pro. Most of our tech devices have relied on lithium-ion batteries, and they have been the mainstay for years, largely due to how stable the technology has become.

However, these days there's a new kid on the block: silicon carbon batteries. These batteries, both in theory and in practical use cases we've seen so far, allow for larger battery capacities. Interestingly, they are not physically larger than lithium-ion batteries, which makes it possible to equip phones with higher-capacity batteries while keeping the devices slimmer, lighter, and less bulky.

Here, we explain what silicon carbon batter...
