About HiTHIUM

HiTHIUM (Xiamen Hithium Energy Storage Technology Co., Ltd.) is a stationary energy storage solutions manufacturer founded in 2019 with a focus on Battery Energy Storage Systems (BESS). The company develops and produces LFP battery cells – including the large-format ∞Cell 1175Ah, the first ESS cell in the kAh range – as well as battery modules and integrated systems for utility-scale, commercial & industrial (C&I), residential, off-grid island grids and AI data centers. Manufacturing spans cell production, PACK and module manufacturing as well as system integration; at the Mesquite, Texas site, modules and storage systems are assembled with 10 GWh of annual capacity. The technology portfolio includes, among others, intelligent electrolyte design, ceramic-coated separators, ultra-thick electrodes and full-tab stacking processes for high cycle durability, safety and cell-to-cell consistency. HiTHIUM supplies customers in over 40 countries and has cumulatively delivered over 200 GWh of battery capacity. In addition to its Chinese sites in Xiamen, Chongqing, Heze and Shenzhen, the company operates a service network with 19 service warehouses and regional technician teams.

Materials & Technologies

LFP

Lithium iron phosphate (LiFePO4)

Cathode material of the storage cells with high thermal stability and long cycle life.

Grafit

High-stability graphite anodes (low lithium loss)

Reduces active lithium consumption during cycling and extends cell life.

Natrium-Ion

∞Cell N162Ah sodium-ion cell

For utility-scale energy storage with over 20,000 cycles of service life and a broad temperature window.

Keramik-Separator

Thermally stable ceramic-coated separator

Increases the critical temperature for thermal runaway and improves the intrinsic safety of the cell.
