MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202617041477 A) filed by Ningde Amperex Technology Limited on March 31, 2026, for Secondary Battery, Electric Device And Preparation Method For Secondary Battery.
Inventor includes Zhang, Yanru.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: A secondary battery (100) comprises a negative electrode sheet (10), wherein the negative electrode sheet comprises a current collector and a first active material layer (2); the first active material layer (2) is arranged on at least one surface of the current collector; and the first active material layer (2) comprises a silicon-based material and a solid electrolyte, and the solid electrolyte is at least partially bonded to the surface of silicon in the silicon-based material. In the secondary battery and the electric device, the solid electrolyte is at least partially bonded to the surface of silicon in the silicon-based material; therefore, the problem of the expansion of the silicon-based material can be ameliorated, and the structural integrity and structural stability of the negative electrode sheet (10) can be enhanced. Moreover, compared with a binder- coated silicon-based material in the prior art, due to the utilization of the solid electrolyte, the lithium intercalation capability of the silicon-based material can be improved, and the ion conduction rate of the negative electrode sheet (10) can be improved, that is, the problem of deteriorated dynamic properties of the secondary battery caused by a binder-coated silicon-based material can be ameliorated.
