  A new generation of lithium-ion battery negative electrode material - silicon dioxide! Due to the rapid development of lithium-ion batteries, people's daily life and production methods have undergone tremendous changes. At present, lithium-ion batteries are needed in everything from laptops, tablets, cameras, mobile phones to new energy vehicles, and lithium-ion battery products have spread to every corner of people's lives.   Lithium- ion battery composition Lithium-ion batteries refer to secondary batteries that use two different compounds that can reversibly embed and extract lithium ions as positive and negative electrodes, respectively. Common lithium-ion batteries on the market are mainly cylindrical, square, button and soft-pack batteries, as shown in Figure 1. Although the appearance of lithium-ion batteries varies, they are basically composed of a shell, a positive electrode material, a separator, a negative electrode material and an electrolyte. The ...

Among many battery technologies, lithium titanate batteries stand out for their excellent safety and are considered the safest type of battery currently. This article will explore the characteristics of lithium titanate batteries in depth and analyze why they are superior to other battery technologies in terms of safety.

Lithium-ion batteries (LiBs) provide power for electric vehicles (EVs), and the anode plays a crucial role in their performance. Graphite materials, with excellent conductivity, thermal stability, and high performance, are the primary anode materials for lithium-ion batteries. Graphite has become the earliest commercialized negative electrode material for lithium-ion batteries due to its advantages such as high electronic conductivity, large lithium ion diffusion coefficient, small volume change before and after lithium insertion in its layered structure, high lithium insertion capacity (theoretical capacity can reach 372mA·h/g), and low lithium insertion potential.
