Battery raw materials are in the spotlight as lithium-ion demand surges alongside growing emphasis on sustainability. Variations in material emission intensities suggest that major decarbonization opportunities exist in raw materials sourcing.

Sodium-ion batteries are emerging as a next-generation alternative to lead-acid starter batteries, offering longer lifespan, higher depth of discharge, and improved low-temperature performance. Unlike lead-acid, which suffers from high self-discharge and maintenance requirements, sodium-ion provides a maintenance-free, reliable solution with 100% depth of discharge and faster recharge rates, making it well-suited for stop-start systems. Industry leaders like Clarios are actively developing low-voltage Na-ion starter batteries, while companies such as Paragonage, Nadion, Sodion, Highstar, and Biwatt have already released specifications. Currently in the validation phase, sodium-ion starter batteries are expected to scale from a few hundred units in 2024 to 350,000 vehicles by 2030, achieving a 110% CAGR. While initial adoption will focus on premium vehicles, emerging markets are likely to drive aftermarket adoption from 2027 onwards, positioning sodium-ion as a high-performance, cost-efficient alternative to lead-acid.
