Publication number: 20240145864Abstract: This application provides a binder and a separator containing same, an electrode plate, and a related secondary battery, a battery module, a battery pack, and an electrical device. The binder includes an organic polymer and an inorganic compound. The organic polymer is polymerized from a first polymerizing monomer containing an ester bond, a second polymerizing monomer containing a nitrile bond, and a third polymerizing monomer containing an amide bond. A weight ratio between the first polymerizing monomer, the second polymerizing monomer, and the third polymerizing monomer is 1:(0 to 0.8):(0 to 0.15), and optionally 1:(0.05 to 0.2):(0.05 to 0.1). When the binder is applied to the separator, the resistance of the separator is reduced, the ionic conductivity of the separator is improved, and the battery performance is improved.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Haiyang Kang, Yi Zheng, Chengdong Sun, Yang Yu, Chuying Ouyang

Publication number: 20130016853Abstract: The present invention provides an audio apparatus capable of noise suppression, including a first signal processing circuit which is set with two input ends and one output end, where one input end is configured to receive noise and the other input end is configured to receive a digital music signal; and a second signal processing circuit which is connected to the output end of the first signal processing circuit. The first signal processing circuit is configured to generate a noise inversion signal, and mix and superpose the noise inversion signal with the digital music signal to obtain a mixed signal. The second signal processing circuit is configured to perform digital/analog conversion and amplification on the mixed signal, and output the signal to an earphone. The present invention further provides a noise-suppressed mobile phone where the earphone does not need to carry a power supply and a signal processing module.Type: ApplicationFiled: September 18, 2012Publication date: January 17, 2013Applicant: HUAWEI DEVICE CO., LTD.Inventors: Chengdong YU, Haibo Shan

Publication number: 20110158332Abstract: The present invention discloses a distributed base station system as well as its networking method and base band unit. In this system, the base band unit (BBU) and RF unit (RFU) of the base station are separated, and the RFU is equipped with base band RF interfaces for interconnecting the BBU and transmitting data information, thereby forming the base station. Based on the separation of the BBU from the RFU, the BBU capacity is further divided at the same time, and every unit is also arranged independently. The BBU networking and capacity expansion may be achieved with capacity expansion interfaces and base band RF interfaces provided by BBU interface units in flexible and convenient ways.Type: ApplicationFiled: March 8, 2011Publication date: June 30, 2011Applicant: Huawei Technologies Co., Ltd.Inventors: Wangjun Wu, Chengdong Yu, Zhu Tan, Tao Pu, Wensheng He, Peng Lan, Jun Zhou, Ming Yu
