from chemistry to pack
Since I know that this is a delicate topic, and many get confused, I will explain very briefly the nomenclature that I used. The IUPAC defines the anode as the electrode at which the oxidation occurs and the cathode as the electrode at which the reduction occurs. Therefore, in a galvanic cell, the negative electrode … Read more
Compaction Density, Silicon Anodes, and What’s Actually Confirmed Our 4th generation LFP post set out the core idea behind LFP “generations”: it’s overwhelmingly a compaction density story applied to the same LiFePO₄ crystal, not a chemistry change, with each generation defined by tighter particle grading, different precursor routes, and progressively higher powder/electrode packing density. 5th … Read more
It is useful to look at an idealised Nyquist Plot of a lithium ion battery. Starting with a detailed, feature-by-feature description of the idealised Electrochemical Impedance Spectroscopy (EIS) Nyquist plot, tracking from the highest frequencies on the left to the lowest on the right. 1. The Axes and Flow 2. The Inductive Artefact (Highest Frequency) … Read more
AION Engineering INC The performance of a lithium-ion cell is fundamentally governed by its material chemistry, particularly the composition of its cathode active material (CAM). In this article, we focus specifically on the role of nickel content in Nickel Manganese Cobalt Oxide (NMC) materials and how it correlates with energy density and power capability. Although … Read more
through Design, Thermal Management, and Revival Techniques Abstract Battery life (longevity) is a cornerstone of electric vehicle (EV) sustainability, particularly in fleet-heavy regions like India, where high usage, climate stress, and inconsistent charging behaviours accelerate degradation. At Yanti Innovative Electromotive Solutions, we focus on a revival-first approach to extend the functional life of EV batteries. … Read more
Author: rhd instruments GmbH & Co. KG Introduction As the solid-state battery field matures and more attention is turned to detailed characterization of interfaces and individual redox processes, the need for a suitable reference electrode (RE) system emerges, in order to enable three-electrode measurements [1, 2, 3]. While the use of standardized REs is well-established … Read more
A look at the 2025 Battery Roadmaps. Perhaps closer to describe this as a start of 2025 review of the latest battery roadmaps, research and funding directions that will shape the industry. Here we look at the four largest cell manufacturers and across the government funded research. The big themes are: As China pushes the … Read more
How does a lithium ion battery work? And how does the mnemonic OIL RIG help us understand the processes? A battery consists of an anode (negative terminal) and a cathode (positive terminal). A polymer separator prevents direct contact, and a liquid electrolyte allows movement of ions between the layers. The anode and cathode are connected … Read more
The mixed chemistry battery pack consists of two types of battery cell with different chemistry in one battery pack. The aim being to offer the best of both chemistries: A look at the power density versus energy density graph. This shows that high power tends to be at the expense of energy. Hence, the question: … Read more
Lithium Rich Manganese (LRM) has a high specific capacity because of both cationic and anionic redox activity and are expected to be developed and applied as cathode materials for a new generation of high-energy density lithium-ion batteries [1]. Note: Lithium Manganese Rich (LMR) ≡ Lithium Rich Manganese (LRM) Quan Li et al [2] show that increasing … Read more
