Xiaomi obtains patent for a stable solid-state electric vehicle battery featuring a multi-layered anode structure.
Chinese tech giant Xiaomi has made a significant stride in the electric vehicle (EV) industry with the patenting of a solid-state EV battery featuring a novel layered electrode design. This innovative battery promises substantial advancements in energy density, fast-charging capability, and manufacturing compatibility.
The heart of the battery lies in its layered electrode structure, which consists of multiple layers of active materials, conductive agents, binders, and a solid electrolyte made of polymers and metal salts. The solid electrolyte permeates through the thickness of the electrode layers, shortening ion transport pathways and thereby enhancing ionic conductivity, improving fast-charging performance.
One of the most impressive aspects of the battery is its energy density and range. The prototype delivers a China Light-Duty Vehicle Test Cycle (CLTC)-rated range of approximately 1,199 km (745 miles) on a single charge, a significant leap for current EV standards. Moreover, it supports rapid charging that can add as much as 805 km (500 miles) of range in just 10 minutes, addressing one of the major challenges of solid-state batteries in high-rate charging applications.
The battery pack also boasts a compact and efficient design. It features a Cell-to-Body (CTB) architecture with 77.8% volume efficiency, making it only 120 mm (4.7 inches) in height. This compact design allows better space utilization and improved weight distribution in EVs, beneficial for both on-road and off-road vehicle platforms.
Xiaomi emphasizes that its solid-state battery design is compatible with current lithium battery manufacturing processes, which could ease adoption and reduce production transition costs in comparison to completely new battery technologies. This compatibility makes the new technology more accessible for mass production and integration into existing EV models.
The development of this compact battery pack marks Xiaomi's formal entry into solid-state battery development. By overcoming ion transport challenges in thick electrodes through its layered design, Xiaomi addresses a critical bottleneck that has hindered widespread deployment of solid-state batteries, particularly for fast charging.
This patent positions Xiaomi as a strong competitor in the evolving EV battery landscape. By potentially reducing its reliance on external battery suppliers and strengthening its position in the EV market where solid-state batteries are seen as the future of energy storage, Xiaomi is poised to make a significant impact in the industry.
