What EEMB does

EEMB is a China-based lithium battery manufacturer founded in 1995 that produces both primary (non-rechargeable) and rechargeable lithium battery cells across five chemistries — Lithium Thionyl Chloride (Li-SoCl2), Lithium Manganese Dioxide (Li-MnO2), Lithium-ion (LIR), Lithium Polymer (LP), and Lithium Iron Phosphate (LiFePO4) — in cylindrical, coin, and pouch form factors. The company also assembles custom battery packs, offering engineering design, prototyping, in-house testing, certification support (UL, UN38.3, IEC, UN), and mass production for OEM customers, alongside accessory products such as battery terminations (PC pins, SMT/SMD, solder tabs, connectors) and battery holders. Its portfolio spans sub-100mAh coin cells up through the 12V-100Ah LiFePO4 deep-cycle energy storage line, including specialized variants such as high-temperature Li-SoCl2 cells rated to +150°C and -40°C Li-Polymer cells.

EEMB sells through a hybrid go-to-market: direct OEM engagement and quote-based custom pack requests via eemb.com and a dedicated DesignMyBattery email channel, a secondary consumer storefront at allthingslithium.com, Amazon US for standard coin-cell packs, and multilingual product literature supporting global reach. Target customer segments include IoT and smart metering, medical and healthcare devices, security and alarm systems, energy storage and light EV (golf carts, RVs, solar), OEM and industrial electronics, and consumer electronics. The company holds certifications including UL, UN38.3, ISO9001, ISO14000, IEC60086, IEC62133, UL1642, and CE.

Revenue is not publicly disclosed and the company is privately held with no parent company, subsidiaries, funding rounds, M&A, partnerships, or named management disclosed in the available data. In May 2026 the US Consumer Product Safety Commission announced a recall of 312,000 EEMB lithium coin battery packs sold on Amazon US between August 2023 and April 2026 for non-compliance with Reese's Law child-resistant packaging requirements — a material regulatory event affecting the consumer-side portion of the business.
