According to information obtained by ETnews from industry sources, Apple seems to be proceeding with a next-generation battery development project with the aim of commercializing it after 2025. Apple is directly involved in the development of battery components such as cathode materials and anode materials in the next generation battery development project, aiming to significantly improve performance than before.
The positive electrode material determines the battery's energy density, output, stability, etc. According to reports, Apple is trying to develop a positive electrode material with a new composition that is completely different from existing ones by combining nickel, cobalt, manganese, aluminum, etc.
Additionally, Apple is reportedly considering using carbon nanotubes as a conductive material to improve the performance of battery materials. A conductive material is a substance that promotes the movement of electrons between the positive electrode active material and the negative electrode active material. Carbon nanotubes, which have recently attracted attention as a conductive material for secondary batteries, can exhibit superior performance with a smaller amount than conventional conductive materials.
Developments are underway to dramatically increase the silicon content of negative electrode materials. Existing batteries use graphite as the negative electrode material, but by using silicon instead, it is said to be possible to increase battery capacity and further shorten charging time. However, when silicon is used as the negative electrode material, there is a problem that the battery volume expands during the charging and discharging process. Therefore, ETnews points out that ``Apple may have secured technology to overcome the expansion problem while using silicon.''
Regarding Apple's next-generation battery development, multiple industry insiders familiar with Apple's affairs said, ``The mobile user experience has expanded with entry into the Metaverse and MR goggle markets, and demand for high-performance batteries has increased.'' He seems to have been involved from the material development stage to improve battery performance.''
It has become clear from around 2018 that Apple is interested in developing its own battery, including the acquisition of human resources and patent applications. Apple has hired an executive from Samsung SDI, a battery development company under the Samsung Group, to oversee the battery development department.
