The type axis of Prepaid Battery Recycling segmentation distinguishes five chemical families: Lithium‑ion, Nickel‑Cadmium (NiCd), Lead‑acid, Alkaline, and Other (including zinc‑air and silver‑oxide). Lithium‑ion batteries dominate the landscape, responsible for approximately 55 % of reclaimed material, driven by their prevalence in portable electronics and EVs and the higher economic incentive to extract cobalt, nickel, and lithium. Nickel‑Cadmium units, once common in power tools and older EV models, now constitute roughly 12 % of the recycling mix, with legacy stockpiles prompting steady processing volumes. Lead‑acid batteries, still used in backup power and certain automotive contexts, contribute about 20 %; their well‑established recycling pathways lower marginal costs, sustaining their share. Alkaline batteries, prevalent in household devices, account for 8 % of the market, reflecting lower per‑unit value but high collection rates. The residual 5 % falls under Other chemistries, where niche recovery processes are emerging. This typology clarifies how each battery chemistry underpins the overall market size and informs strategic investment decisions.
