Korean media reports: Apple develops new batteries with high energy density to provide longer battery life for AR/VR devices

According to Korean media "ET News", Apple is developing a new high-performance battery that improves energy density and charging rate and may be put into use after 2025. It is expected that this kind of battery will be used in Vision Pro or other subsequent head-mounted products to improve battery life or optimize product form

According to ET News, multiple industry insiders familiar with Apple's situation said: "With the expansion of mobile user experiences such as the Metaverse and mixed reality, the market demand for high-performance batteries is increasing. In order to improve battery performance, Apple We have been working hard from the material development stage.”

It is reported that the battery uses a new cathode composition that is "completely different" from existing batteries and is designed to increase energy density and charging rate. Among them, the research and development of cathode materials is developing in the direction of greatly increasing the silicon content. If silicon is used instead of graphite, this can increase battery capacity and shorten charging and discharging times. But the problem is that silicon has a volume expansion problem during charging and discharging. ETNews says Apple may have found a solution to this problem.

Apple is studying the use of carbon nanotubes as conductive materials to increase charging rates. This is just a solution that Apple is exploring. It is unclear whether it has actually been successful, which solution will be successful, and how long it will take to be actually applied.

According to reports, Apple has been developing this kind of battery since at least 2018, and has set a commercial target of 2025.

It is worth noting that Apple is expected to use new high-performance batteries with improved energy density and charging rate in Vision Pro or other subsequent head-mounted products to improve battery life or optimize shape parameters.

The Vision Pro, which will be released early next year, uses an external battery, but even so, Apple says it can only achieve about 2 hours of battery life. It can be seen that battery life is an important limiting factor for the current XR all-in-one machine. Unlike other mobile devices such as phones and tablets, headsets must continuously sample and process multiple sensor inputs while rendering the entire environment at high resolutions and frame rates, which places high demands on the CPU, GPU, and battery

If the energy density and charging rate can be indeed improved, the battery life of the headset can be greatly improved, or its shape parameters can be optimized, thereby improving the user experience
