from chemistry to pack
As you charge a cell it expands, when you discharge a cell it contracts and as the cell ages over its lifetime we see a continuing cell expansion. Thus the cell expansion can be divided into: The reversible cell expansion comes from changes in graphite layer spacing associated with different graphite-lithium intercalation compounds induce reversible … Read more
Niobium in batteries looks at the high level addition of this element and some of the claimed and measured improvements to the battery cells as a result. Niobium-Based Anode Toshiba Super Charge ion Battery (SCiB) [5] have a Niobium Titanium Oxide anode and have improved performance: Downside: Cycle life, charging and cold performance are all … Read more
When looking at the key parameters in fast charging a battery pack it is worth looking at the complete system. Also, it is good to look from the cell at atomic scale through the thermal system design to the charging algorithms and handshakes [1]. The drive for a 10 min fast charge to reach 80% … Read more
