Mkpa Pụrụ Iche 1: Ezigbo Nguzogide Ngwa Electtrolyte dị iche iche

Lithium batrị electrolyte na-emebi emebi nke ukwuu, yabụ nguzogide kemịkalụ bụ ngosipụta arụmọrụ dị oke egwu nke akwa akwa okpomọkụ PTFE:

Organic Solvents  Main electrolyte components dị ka Ethylene Carbonate (EC) na Dimethyl Carbonate (DMC) bụ ihe mgbaze pola siri ike. Plastics nkịtị ga-aza ma ọ bụ ọbụna gbazee mgbe ekpughere ya, ebe PTFE na-anọgide na-enweghị mmetụta.

Corrosive Electrolytes  Lithium Hexafluorophosphate (LiPF₆), nnu bụ isi electrolyte, na-enwe mmetụta maka mmiri na okpomọkụ ma na-agbaze ngwa ngwa iji mepụta Hydrofluoric Acid (HF). HF na-emebi emebi nke ukwuu ma nwee ike imebi iko na ọtụtụ ọla. PTFE akwa okpomọkụ dị elu na-enye nguzogide dị ịrịba ama na hydrofluoric acid ma na-ejigide arụmọrụ kwụsiri ike na gburugburu ebe siri ike.

Electrochemical Stability  N'okpuru nnukwu voltaji na chaja na-arụ ọrụ ọnọdụ n'ime batrị, PTFE nwere njirimara kemịkalụ kwụsiri ike, na-adịghị emepụta mmeghachi omume n'akụkụ ya na electrolyte yana enweghị ire ere nke electrolyte.
