Example Embodiment

[0050] Since lithium cobalt oxide (LiCoO 2 ) has limitations in performance, poor stability, and is easy to decompose to generate gas and release heat, resulting in combustion or explosion. Therefore, it is necessary to develop a positive active material that can replace it, so as to reduce costs and improve battery performance.

[0051] The performance of a lithium-ion battery depends primarily on the structure and properties of the materials used inside the battery. These battery internal materials include positive electrode materials, negative electrode materials, electrolytes, separators, and the like. Among them, the selection and quality of positive and negative electrode materials directly determine the performance and price of lithium-ion batteries. Therefore, research on low-cost, high-performance positive and negative electrode materials has always been the focus of the development of the lithium-ion battery industry. To measure the quality of lithium-ion battery c...

Description

technical field [0001] The invention relates to a battery positive electrode slurry formula and a positive electrode sheet production method, in particular to a battery positive electrode slurry formula containing lithium manganate and a positive electrode sheet production method. Background technique [0002] As we all know, with the rapid development of the domestic mobile phone industry, the development of mobile phone batteries has also changed from the initial combination of cadmium-nickel and hydrogen-nickel to the current single lithium-ion secondary battery. The cost performance requirements for mobile phone batteries are getting higher and higher. The inevitable trend of industry development. As an integral part of mobile phones, lithium-ion secondary batteries are increasingly valued by mobile phone manufacturers and users for their safety performance, electrochemical performance and price. With the rapid popularization of mobile phones in China in recent years, l...
