British battery startup Britishvolt has announced the development of a new 4690 cylindrical ternary lithium battery cell.
Britishvolt said that in the future, electric vehicle batteries will develop towards "large-scale", and the 4690 battery is the most potential solution at present. From the perspective of vehicle batteries, the battery cell is the unit that constitutes the basic electrical energy storage. From the perspective of a cylindrical battery cell, if the volume of a single battery increases, under the condition that the total energy remains unchanged, the shell and other materials can be reduced. It has the advantages of reducing weight and cost.
It is understood that the battery cells will be developed at its German EAS factory. In May this year, Britishvolt acquired German battery developer and manufacturer EAS from Bulgarian company Monbat for 36 million euros. Shortly after the acquisition of EAS, its Helmshall factory also announced an expansion.
Britishvolt believes that larger battery cells are "a key driver of the future battery industry". Britishvolt said it will customize the battery cells according to customer requirements, including changing the length of the 4690 to suit specific applications.
