MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202514028820 A) filed by Ningde Amperex Technology Limited, Ningde, China, on March 26, for 'electrochemical apparatus and electronic device.'

Inventor(s) include Jianyu Liu; Rui Wang; Chao Tang; and Xiang Wang.

The application for the patent was published on Oct. 10, under issue no. 41/2025.

According to the abstract released by the Intellectual Property India: "This application discloses an electrochemical apparatus and an electronic device, where the electrochemical apparatus includes a negative electrode plate and an electrolyte. The negative electrode plate includes a negative electrode current collector and a negative electrode film layer disposed on at least one surface of the negative electrode current collector. In a direction facing away from the negative electrode current collector, the negative electrode film layer sequentially includes a first active substance layer and a second active substance layer, where a mass percentage of a silicon material in the first active substance layer is less than a mass percentage of the silicon material in the second active substance layer. The electrolyte includes a substance A with a structure shown in formula I. formula I This application can improve the cycling performance of the electrochemical apparatus, especially the deep discharge (discharge cutoff voltage 3.0 V) cycling performance, and take the thermal performance of the electrochemical apparatus into account."
