Breaking the fast charging bottleneck! Shanghai Jiao Tong University & Southern University of Science and Technology join forces: Super-wetting electrolyte reshapes the SEI layer, comprehensively improving lithium battery performance. Recently, Professor Wan Jiayu’s team at Shanghai Jiao Tong University, in collaboration with Professors Liu Ke, Luo Guangfu, and Deng Yonghong from Southern University of Science and Technology, published a groundbreaking study in the top journal ACS Energy Letters (IF: 22.0). They proposed a general “stepwise liquid injection” interface engineering strategy, successfully constructing a uniform, stable, and inorganic-rich SEI layer on a graphite anode using an ultra-low concentration of superwetting electrolyte. This breakthrough overcomes multiple bottlenecks in wettability, SEI stability, and

When the electrolyte fails to reach every microscopic corner of the battery uniformly, performance degradation and safety risks quietly lurk. The energy density, lifespan, and safety of lithium-ion batteries are inseparable from the uniform and sufficient ‘wetting’ of the electrolyte within the cell. The process is akin to rainwater seeping into the soil—it must penetrate deeply enough and distribute uniformly. However, as cell designs become increasingly complex and energy densities continue to rise, this seemingly simple ‘wetting’ process has evolved into a critical bottleneck restricting battery performance. What is Electrolyte Wettability? In essence, electrolyte wettability is the ability of the electrolyte to penetrate and spread through porous media, such as

About fast charging, how do the batteries in Xiaomi phones, Apple phones, and Tesla electric vehicles achieve fast charging? You’ll find out if you keep reading. With the widespread application of lithium-ion batteries in electric vehicles, portable devices, and energy storage systems, there is a growing demand for faster and more convenient charging experiences. However, high-rate fast charging significantly increases the electrochemical load on electrode materials, accelerating various aging mechanisms such as lithium deposition, structural degradation, and thermal runaway, thus affecting battery performance, safety, and lifespan. Therefore, developing charging protocols that achieve both fast charging and stable electrochemical and thermal management has become a key challenge in current battery research

How to determine the charge/discharge cut off voltage of a lithium-ion battery? And what is charge/discharge cut off voltage? What is charge/discharge cut off voltage? The charge/discharge cutoff voltage refers to the upper and lower limits of the voltage set during the charging and discharging process of a lithium-ion battery to avoid battery damage, ensure safety, and extend its service life. Charging Cut-off Voltage: Definition: The highest voltage a battery is allowed to reach during charging. When the battery voltage reaches this value, the charging process must be stopped or switched to trickle charging/stop charging. Purpose: (1) Prevent overcharging: Continuing to charge beyond the cut-off voltage is called overcharging. (2)

The ever-increasing demand for large-size lithium-ion batteries from electric vehicles has driven the accelerated development of cell specifications with higher energy density and better pack efficiency. By the end of 2024, electric vehicles accounted for approximately 4% of the global passenger vehicle fleet, and this is projected to quadruple by 2030. For automotive applications, LIB (Lithium-ion Battery) R&D revolves around cost, energy density, and power capability, while also considering safety and lifespan, resulting in various chemical systems, cell specifications, and integration solutions. EV batteries range from 18650 cylindrical cells (≈3 Ah) to large-size pouch and prismatic cells exceeding 100 Ah, each with trade-offs in cycle life, thermal performance, energy density,
