StoreDot, the Israeli innovator of fast charging EV batteries, now has announced a new 4695 cylindrical battery format. With 46mm diameter and 95mm height, it offers several advantages for electric vehicles (EVs), according to StoreDot founder and CEO Doron Myersdorf.
One of the major steps forward is Increased energy density. Compared to smaller cylindrical cells like the 2170, the 4695 format allows for a significant increase in energy density. This means that more energy can be packed into the same space, leading to longer driving ranges for EVs.
Myersdorf also said that the larger size of the cells can contribute to improved thermal management and stability. The risk of thermal runaway and fires can thus be reduced. Higher power output can improve acceleration and overall vehicle performance.
StoreDot believes that simplified manufacturing could be a plus for the new cell format. “While still relatively new, it’s anticipated that the 4695 format could offer some manufacturing efficiencies compared to other formats, potentially leading to lower costs.”
The new prismatic XFC silicon-dominant battery cells target 170Ah cell capacity with volumetric energy density surpassing 700Wh/L, the company said.
Some EV OEMs are applying the 4695 battery format, for example the US vehicle manufacturer Rivian, which has announced it will use LG Energy Solution’s 4695 batteries in its upcoming R2 models. Also, BMW Group is planning to use 4695-format cylindrical cells in its next-generation EVs, alongside 46120 cells.
CEO Myersdorf also said that while Tesla pioneered the 4680 format (similar diameter but shorter height), it remains to be seen how widely the 4695 format will be adopted across the industry. However, the advantages it offers in terms of energy density, safety, and performance make it a promising option for EV manufacturers looking to improve their vehicles and achieve faster charging times.
