Another “Nature” about battery: A ductile solid electrolyte interphase for solid-state batteries Solid-state lithium metal batteries are facing huge challenges under practical working conditions. Even when the ionic conductivity of composite solid-state electrolytes is increased to 1 mS cm−1, it is still difficult to realize long-life cycling of solid-state batteries above a current density of 1 mA cm−2 and an areal capacity of 1 mAh cm−2 (ref.). The fundamental cause is the brittle nature of the solid–electrolyte interphase (SEI) with sluggish lithium-ion transport and the resulting lithium dendrites and severe side reactions. Here we report a ductile inorganic-rich SEI that retains its structural integrity while allowing easy ion diffusion at high current densities and areal capacities.

Q1: About CAN and RS485, which are the basic improvements and functionalities that battery module or pack communication incorporates into NEWARE software? Can this data be saved in the database? Communication allows the device to communicate with the BMS (Battery Management System) in your battery. Once communication is established, the test page will display information such as the cell voltage. You can view the cell voltage information and then configure your software. For example, you can set the test to end when the cell voltage reaches 3.65V or trigger an alarm if the cell voltage is abnormal. The data obtained through communication from the BMS will be saved and will

7 most anticipated battery technologies in 2025, the first one is Sodium-ion batteries. Image source: CATLSodium-ion batteries hold great promise because they replace scarce lithium with abundant sodium, eliminating the need for cobalt and nickel. While the energy density of this chemistry still lags behind lithium-ion batteries, it offers a low-cost, non-flammable, and highly durable alternative.CATL’s recently launched sodium-ion battery (Naxtra) is a prime example of the industry’s high expectations. It retains 90% of its power at -40°C, boasts an impressive energy density of approximately 175 Wh/kg, and has a cycle life exceeding 10,000 charge-discharge cycles. Safety is a major selling point for CATL, as the battery demonstrated “no smoke,

All Solid State Battery with Soft Carbon–TiSi2 Multilayer Structure for Optimized LiSi Anodes Sulfide-based all-solid-state batteries, with their excellent safety and high theoretical energy density, are considered a key development direction for next-generation high-energy-density energy storage technology. However, their practical application is limited by the performance shortcomings of anode materials: traditional graphite anodes are difficult to match the ever-increasing energy density requirements, while lithium metal anodes are plagued by dendrite growth and interfacial side reactions. Against this backdrop, silicon-based anodes, with their significant advantages of ultra-high theoretical capacity (3579 mAh g⁻¹) and low operating potential (0.4 V vs. Li⁺/Li), have become a highly promising alternative. In recent years, research on

AFM: Dynamic pH regulation and interfacial ion redistribution of dendrite-free zinc metal anodes via molecular buffering Reference link:  https://doi.org/10.1002/adfm.202514260 Research Overview Aqueous zinc-ion batteries (Zn-ion batteries) suffer from irreversible anode performance degradation caused by electrolyte alkalinization and uneven Zn deposition driven by the hydrogen evolution reaction (HER). This study proposes a bifunctional buffer additive that synergistically combines pH regulation and interfacial ion redistribution. This buffer additive maintains a self-regulated electrolyte pH (≈3) through a proton donor-acceptor equilibrium, effectively scavenging hydroxyl ions to prevent Zn passivation. It also induces preferential adsorption of Na⁺ on protrusions, promoting planar Zn deposition through a charge screening effect. This dual mechanism enables Cu-Zn half-cells to

Application of Cyclic Voltammetry (CV) in Lithium Battery Research Cyclic voltammetry is a commonly used electrochemical testing technique that cyclically scans the electrode potential at a constant rate and measures the corresponding current response. I. Basic Principles and Testing Methods of Cyclic Voltammetry (CV) Apply a linearly varying voltage (e.g., from 2.6V to 3.9V and back to 2.6V, at a scan rate of 0.2mV/s for 5 cycles) to the working electrode (e.g., the positive or negative electrode of a lithium battery).
