from chemistry to pack
Where the benchmark report asks how Estes Energy Magnus compares numerically to other packs, this one asks a narrower question: is magnesium actually the right enclosure material, on the physics and the evidence published so far. Magnus is used throughout as the worked example because it is the only near-production attempt at this scale; every … Read more
AION Engineering INC While silicon (SiOx/SiC/Si) based anodes skyrocket battery capacity, their swelling character reaching up to 300% volume expansion transforms cell design from a purely electrochemical challenge into a brutal mechanical packaging problem. It is not just about how much lithium the active material can store; how the casing structurally resists (its rigidity) when … Read more
AION Engineering INC Role of Tabs in Current Flow During discharge, the current generated by electrochemical reactions flows through the sequence: Active Material → Conductive Additive → Current Collector → Tab The tab serves as the final current-carrying element in this path. Its current-carrying capacity is therefore a critical factor that affects both electrical efficiency … Read more
AION Engineering INC All cells discussed here are 18650 NMC cells. Balancing Energy Density and Safety Using silicon-based additives in the anode requires a delicate trade-off in cell design. While silicon increases the energy density, it also brings significant challenges for cell safety. Why More Space is Needed Silicon expands and contracts during charge-discharge cycling, … Read more
The lithium-ion (Li-ion) battery didn’t make headlines immediately — it took nearly two decades for the world to truly appreciate its potential. What makes its origin story unique is that it wasn’t developed in a single lab or even by a single team. Instead, it was the result of separate breakthroughs made by scientists in … Read more
Copper surface corrosion is an important subject when considering copper busbar joints. When copper is exposed to air and moisture, it forms a thin layer of reddish-brown copper oxide and other corrosion products. These products are not as conductive as the copper, leading to increased resistance at the joint. The increased resistance leads to local heating … Read more
