Representatives of both DNV and Shmuel-De-Leon Energy (SDLE) consultancies raised the issue of sodium battery technologies during a discussion of the cost evolution of vehicle batteries at the Battery Cells and Systems Exhibition last Thursday, with DNV considering the technology an afterthought being developed too late and missing its commercial window, while SDLE sees the technology as a future mainstay of the micro-mobility markets taking a chunk away from lithium phosphate battery demand in the lower rungs of the market. DNV argues that the rate of uptake of lithium-ion batteries will effectively prevent the economic development of sodium ion battery, as low-cost lithium-iron-phosphate (LFP) batteries in particular still have room to fall in price. Specifically the representative said $50/kWh wasn’t…
