Welion achieves 824 Wh/kg energy density in lab, targets 1000 Wh/kg

January 16, 2026

Welion achieves 824 Wh/kg energy density in lab, targets 1000 Wh/kg China’s solid-state battery company Welion New Energy Chairman Yu Huigen has revealed a breakthrough in solid-state battery technology, announcing that the company has achieved an industry-leading energy density of 824 watt-hours per kilogram (Wh/kg) in laboratory tests, with future targets exceeding 1000 Wh/kg. Yu stated during a recent TV programme, Dialogue, of Chinese state media CCTV, "Our laboratory tests have demonstrated solid-state batteries with energy densities reaching 824 Wh/kg, and we expect to break the 1000 Wh/kg barrier in the long term" Despite the technical breakthrough, Yu acknowledged that cost factors, particularly expensive raw materials in sulfide-based electrolyte systems,

Design, Assembly, and Testing of Full Coin Cells: Tutorials and Case Studies 1. Introduction of Full Coin Cells A full cell is a complete battery system comprising a cathode, anode, separator, electrolyte, and casing. Unlike half-cells, full cells provide an accurate assessment of the electrochemical and mechanical performance of a battery under actual operating conditions. While a half-cell typically utilizes a metal sheet or foil (such as lithium metal) as the counter electrode, a full cell is composed of two active electrodes—one functioning as the cathode and the other as the anode. The design and assembly of a full cell require the consideration of multiple factors, including the selection of

Why is your CV curve asymmetrical? 2026 post

January 12, 2026

Why is your CV curve asymmetrical? This article provides a detailed introduction to the fundamental principles and applications of Cyclic Voltammetry (CV). It analyzes the symmetry of CV curves, specifically focusing on peak potential separation and peak current ratios, while exploring the underlying causes of asymmetry—such as quasi-reversible and irreversible reactions, coupled chemical reactions, and diffusion- versus adsorption-controlled processes. Finally, the article discusses the practical applications of CV curve asymmetry in evaluating catalyst activity, battery rate performance, and the capacitive characteristics of supercapacitors. What is cyclic voltammetry (CV)? Neware battery cyclers 8002 with CV Cyclic Voltammetry (CV) involves applying a cyclic potential that varies linearly with time to a working
