Lithium ion battery electrolyte   The electrolyte of lithium-ion batteries is one of its key components, mainly responsible for conducting lithium ions between the positive and negative electrodes of the battery, thereby achieving the storage and release of electrical energy. The type of electrolyte has a significant impact on the battery’s performance, safety, and lifespan. The electrolytes of lithium-ion batteries are mainly divided into two major categories: liquid electrolytes and solid-state electrolytes. Liquid electrolytes are the earliest type of electrolytes used, typically composed of organic solvents (such as carbonate esters) and lithium salts (such as lithium hexafluorophosphate, LiPF6). This type of electrolyte has good ionic conductivity and low viscosity, allowing

NEWARE battery testing system, with its exceptional technical performance, provides strong support for the parameter assessment of new energy vehicles.

Lithium-ion batteries, as the most mainstream rechargeable battery technology, have developed rapidly in recent years. The energy density and charging speed of new lithium-ion batteries continue to increase, and the cost continues to decline. At the same time, people have also turned part of their attention to improving battery life, safety and so on. Among them, estimating the state of charge ( SOC ) of the battery is one of the effective methods.   In recent years, there are many methods to estimate the SOC of lithium-ion batteries, such as traditional estimation methods, model-based estimation methods and data-driven estimation methods. However, each type of method still has shortcomings. Traditional estimation

Since its commercialization by Sony in 1991, lithium-ion battery technology has seen significant advancements due to its high energy density and efficiency. In 2022, the global inventory of electric vehicles exceeded 26 million units, marking a 60% increase from the previous year. Today, lithium-ion batteries have developed into various forms, ranging from standard 18650 cylindrical cells with capacities of around 3Ah to large pouch or prismatic batteries with capacities exceeding 100Ah. The 4680 battery (46mm in diameter and 80mm in axial length) offers higher energy and power advantages compared to commonly used 18650 or 21700 cylindrical cells. Compared to the 21700 battery, its volume is 5.5 times larger. This large
