Which new materials are being explored for smartphone batteries?

Question

Accepted Answer

New materials are being explored for smartphone batteries to improve capacity and charging times.

Manufacturers are actively researching and developing alternative battery technologies beyond current lithium-ion models. These efforts are driven by consumer demand for faster charging and longer battery life, particularly with the increasing power requirements of AI features and demanding applications. The goal is to create batteries that are more potent, charge quicker, and last longer than existing options, allowing device makers to differentiate their products in a competitive market.
Silicon-carbon technology is being implemented in flagship devices.

Chinese manufacturer Honour has developed a new higher capacity battery technology that utilises silicon-carbon. This innovation is featured in their AI-infused flagship smartphone, the Magic 6, which reportedly achieves a full charge in under 40 minutes and offers superior longevity compared to competitors. This development places Honour's battery at the top of rankings compiled by DXOMARK, a commercial entity that scientifically assesses mobile handsets.
Solid-state batteries are under development by major players.

South Korean technology giant Samsung is reportedly developing a solid-state battery. This next-generation technology promises enhanced energy storage, faster charging capabilities, and improved safety features. Samsung aims to introduce this solid-state battery to the market by 2027. Additionally, Apple, which recently surpassed Samsung as the world's leading smartphone vendor, is also reported to be developing its own proprietary battery technology, with potential integration into mobile devices as early as 2025.
Lithium-sulfur and graphene are being investigated as alternatives.

To overcome the limitations of current lithium-ion batteries, which rely on scarce and increasingly expensive materials like lithium, cobalt, and manganese, manufacturers are exploring alternative chemistries. These include lithium-sulfur and graphene. These materials are being investigated for their potential to offer longer lifespans and to reduce reliance on less common elements, addressing both performance and supply chain concerns.
