Title: Sihui Wang: Innovator in Battery Technologies
Introduction
Sihui Wang is a prominent inventor based in Ningde, China, known for his significant contributions to the field of battery technologies. With a total of 8 patents, Wang has focused on developing advanced materials and apparatuses that enhance the performance and efficiency of electrochemical energy storage systems.
Latest Patents
Wang's latest patents include innovations such as a pressure-resistant positive active material and an electrochemical energy storage apparatus. This application specifically addresses the need for a pressure-resistant positive active material, which consists of secondary particles made up of primary particles. The quantity of primary particles per unit sphere area in a scanning electron microscope (SEM) graph of the secondary particles ranges from 5/μm² to 30/μm². The single-particle pressure-resistant strength of these secondary particles is between 60 MPa and 300 MPa. The molecular formula for this positive active material is LixNiyCozMkMepOrAm, with specific constraints on the values of x, y, z, k, p, r, and m. This innovative material boasts a compact particle structure and high single-particle pressure-resistant strength.
Another notable patent involves a positive active material, a positive electrode plate, and an electrochemical energy storage apparatus. The positive active material is identified as LiNiCoMMeOA, or LiNiCoMMeOA with a coating layer on its surface. The particle size of the positive active material is controlled to ensure that D10 falls within the range of 0.3 μm to 2 μm. This careful control of particle morphology and micro powder content effectively reduces side reactions with the electrolyte solution, decreases gas production, and improves the overall storage performance of the electrochemical energy storage apparatus without compromising energy density, cycle performance, or rate performance.
