MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617071183 A) filed by Batterotech Co. , Ltd. on June 08, 2026, for Negative Electrode Sheet, Battery, Battery Pack, And Electric Device.
Inventors include Liu, Jian; and Huang, Haining.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A negative electrode sheet (100), a battery (300), a battery pack, and an electric device, which relate to the technical field of secondary batteries. The negative electrode sheet (100) comprises a current collector (110), a tab (130) connected to one side of the current collector (110), a first active material layer (150), and a second active material layer (170). The front and back surfaces of the current collector (110) are coated with the first active material layer (150), and the thickness (150) of the first active material layer is gradually increased and then gradually reduced from the tab (130) side to the side away from the tab (130). The outer side of the first active material layer (150) is coated with the second active material layer (170), and the thickness of the second active material layer (170) is gradually reduced then gradually increased from the tab (130) side to the side away from the tab (130). The negative electrode sheet (100) provided herein can alleviate the problem of lithium plating, and can improve the safety of the battery (300).
