Xiaomi's new high-silicon lithium battery technology promises 10% more capacity at the same volume

While the smartphone industry has made strides in both camera and silicon hardware, improvement in battery technology has plateaued rather painfully. Until now, at least, as it appears that industry giants Xiaomi are finally set to bring some much-needed advancements to battery tech.

As announced hours ago, Xiaomi has now developed new smartphone battery technology that could see OEMs move on from the age-old lithium-ion tech currently in use. The company looks to be pushing its new High-Silicon Lithium battery technology, with the most notable selling point being a 10% increase in battery capacity at the same volume. In simpler terms, for example, Xiaomi's technology will deliver 5500 mAh from a battery unit with a volume equivalent to current 5000 mAh units. It may not sound like much but it's a solid improvement over current volumetric efficiencies.

Xiaomi claims that it has increased silicon content by 300% on the negative electrodes. That, in addition to an in-house chip and advanced algorithms, should see battery performance heavily improved. The company has also confirmed that mass production of the new high-silicon lithium batteries is scheduled for H2 2022.
