Lithium-ion batteries have been powering our devices for over three decades, and they’ve only evolved ever since. However, the technology has nearly reached a saturation point in charge-holding capacity, so the time has come for an alternative. Enter Silicon Carbon batteries. Denser and capable of holding more charge, these batteries are paving the way for devices that last longer while maintaining or even shrinking down the form factor of these devices. Here’s everything you need to know about them.
What Are Silicon Carbon Batteries?
Silicon Carbon batteries are the latest innovation in portable battery-powered devices and are predominantly being used in smartphones. They’re denser than Li-ion batteries, packing more charge in the anode, while being almost similar in dimensions or even slimmer than regular Lithium-ion batteries.
By leveraging Silicon Carbon battery tech, manufacturers can include bigger capacity batteries in their devices without compromising on the overall form factor of the devices. Thanks to their density, these batteries can store around 25% more charge. So, technically, a Silicon Carbon battery with the exact same dimensions as a 5,000 mAh Li-ion battery offer up to 6,200 mAh of power.
While the maximum theoretical density of Lithium-ion batteries is about 387 WH/kg, Silicon Carbon batteries can far exceed that threshold at 600 WH/kg. Pure Silicon can hold 3500 WH/kg, but that leads to rapid expansion. Hence, carbon is introduced to stabilize the material.
