What's the highly anticipated stacked battery technology on the Galaxy S24 and iPhone 15?

This advanced technology is commonly employed in the electric vehicle industry, significantly enhancing battery life. So, how exactly is stacked battery technology structured? Let's delve into it in this article.

What is stacked battery technology?

Introducing a groundbreaking battery technology under development for smartphones. It's designed to increase smartphone battery capacity without increasing their physical size. This is achieved by stacking multiple battery cells on top of each other, rather than placing them side by side.

There are numerous benefits to using stacked battery technology. Firstly, it delivers high battery capacity within the limited interior space of the phone. This is crucial for smartphones where users expect extended battery life without compromising device size. Secondly, stacked batteries enable faster charging speeds by allowing simultaneous charging of multiple battery cells, effectively reducing overall charging time.

The Samsung Galaxy is rumored to be one of the first smartphones to feature stacked batteries. It's expected to have a 5,000mAh battery, significantly larger than the current model's battery. However, thanks to the utilization of new technology, the upcoming Galaxy S model will maintain a similar device size compared to the previous generation.

In addition to the Galaxy S24, Apple is also rumored to adopt this new battery technology for the upcoming iPhone 15 lineup.

How does stacked battery technology differ from current rollable battery technology?

Rollable battery technology is a conventional method for producing battery cells. In this process, positive and negative electrodes are rolled together in a spiral shape. While this approach is simple and cost-effective, it also has limitations. One of them is uneven density within the battery, which can lead to malfunctions.

Stacked battery technology is a modern approach to creating battery cells. Positive and negative electrodes are stacked on top of each other, layer by layer. This creates a more uniform internal structure, enhancing performance and longevity. Stacked battery technology also saves space, allowing for higher energy density in battery cells compared to rollable battery technology.

• Extended battery life: Charging stacked batteries on top of each other can increase smartphone battery capacity by up to 50%. This enables users to have robust battery life without increasing device size.
• Faster charging speed: Stacked batteries will bring faster charging technology. Multiple battery cells can be charged simultaneously, reducing overall charging time.
• Smaller form factor: Stacked battery technology allows for smaller smartphones without sacrificing battery life. This is because multiple battery cells can be stacked on top of each other, saving space.

• Cost: Stacking batteries incurs higher costs compared to traditional battery technology. Precise stacking and arrangement of multiple battery cells increase production costs.
• Safety: Improper management of stacked batteries can pose safety risks. Batteries may become excessively hot and prone to ignition if not properly cooled.
• Reliability: This is a relatively new technology, and its long-term performance is still uncertain.
