Lithium iron phosphate ion battery refers to a lithium ion battery with lithium iron phosphate as a positive electrode material. Ny fitaovana electrode tsara amin&39;ny bateria lithium-ion dia zava-dehibe ho an&39;ny organte lithium cobalt, lithium manganate, asidra nikela lithium, fitaovana telo-dimensional, lithium vy phosphate, sns. Anisan&39;izany, ny lithium vy phosphate dia fitaovana tsara ampiasaina amin&39;izao fotoana izao amin&39;ny ankamaroan&39;ny bateria lithium-ion.

Lithium vy phosphate ion bateria fonosana mila mampitombo, hanatsarana lithium bateria ambany hafanana fampisehoana. What is the factor affecting the low temperature energy of the lithium phosphate ion battery pack? For the lithium iron phosphate ion battery pack, industry experts have made more detailed research on its low temperature characteristics, the reasons: 1. Production environment: lithium iron phosphate ion battery Package is a high-tech product that has a large chemical raw material.

Its production environment has a high requirements for temperature, humidity, dust, etc., and if there is no control, the battery quality will fluctuate. 2, mahantra conductivity, miadana lithium ion diffusion hafainganam-pandeha.

Rehefa avo lenta ny fiampangana sy ny fivoahana, ny tena vola dia ambany, ity olana ity dia teboka sarotra hamerana ny fampandrosoana ny indostrian&39;ny lithium vy phosphate. Lithium iron phosphate dia tsy manana fampiharana maro be loatra ka tara loatra, olana lehibe izany. 3, ny fiantraikan&39;ny fitaovana, ny lithium vy phosphate positive electrode dia somary mahantra, ary ny polarization dia mora amin&39;ny polarization, mampihena ny fahafahan&39;ny fahafaha-manao; Ny tsato-kazo ratsy dia manan-danja amin&39;ny fiampangana hafanana avo, satria misy fiantraikany amin&39;ny olana momba ny fiarovana; Ny iray, mety hampitombo ny viscosity amin&39;ny mari-pana ambany, ny lithium ion fifindra-monina impedance dia hitombo; ny fahefatra dia ny binder, ary io koa dia somary lehibe.

How to improve the lithium iron phosphate ion battery pack low temperature performance? We raise low temperature performance of lithium iron ion battery pack from the positive electrode, negative electrode, electro-hydraulic, and binder. Amin&39;ny lafiny tsara, izao dia nanomechanika, ny haben&39;ny potiny, ny fanoherana ary ny mpamboly ax planar AB dia hisy fiantraikany amin&39;ny toetran&39;ny hafanana ambany amin&39;ny bateria manontolo. Ny dingana samihafa dia manana fiantraikany samihafa amin&39;ny electrode tsara, ary ny toetran&39;ny batterie ambany kokoa amin&39;ny mari-pana amin&39;ny 100 ka hatramin&39;ny 200 nano-particle savaivony phosphate, izay afaka mamoaka 94% amin&39;ny -20 degre, izay ny savaivony amin&39;ny nanofence manafohezany ny lalan&39;ny fifindra-monina, Izany koa dia manatsara ny fahombiazan&39;ny hafanana ambany sy ny fivoahana, satria ny lithium .

Raha jerena ny fiampangana toetra avy amin&39;ny electrode ratsy, ny mari-pana ambany fiampangana ny Lithium Ion bateria dia zava-dehibe, anisan&39;izany ny sombintsombiny haben&39;ny poti habe sy ny haavon&39;ny ny ratsy electrode, mifidy telo samy hafa solon-grafit ho electrode ratsy mba hianatra sosona samy hafa elanelana sy ny sombintsombiny habe tsiroaroa hafanana ambany vokatry ny toetra. Avy amin&39;ny fitaovana telo, ny grafit voamadinika amin&39;ny sosona dia lehibe, avy amin&39;ny impedance, ny impedance vatana sy ny impedance fifindran&39;ny ion dia somary kely. Eo amin&39;ny resaka fiampangana dia tsy lehibe amin&39;ny maripana ambany amin&39;ny ririnina ny fonosana batterie lithium-ion, ary zava-dehibe ny fiampangana ny mari-pana ambany.

Because in horizontal flow ratio, 1C or 0.5C cross-flow ratio is very critical, to constant pressure to be very long, by improving three different graphite comparisons, one of which has a relatively large improvement in -20 degree charging constant flow ratio From 40% to 70%, the layer spacing is increased, and there is also a decrease in particle size. Ity ampahany amin&39;ny electrolyte, amin&39;ny -20 degre, -30 degre, ny electrolyte, nitombo viscosity, ary manimba ny fampisehoana.

Electrolyte avy amin&39;ny lafiny telo: solvent, lithium sira, additive. Ny solvent dia manana fiantraikany amin&39;ny mari-pana ambany amin&39;ny fonosana batterie lithium vy phosphate ion avy amin&39;ny 70% ka hatramin&39;ny 90%, miaraka amin&39;ny teboka am-polony mahery; faharoa, samy hafa Lithium sira dia misy fiantraikany amin&39;ny toetra mampiavaka ny ambany hafanana fiampangana sy ny fivoahana. Nametraka ny rafitra solvent sy ny Lithium sira fototra, ny mari-pana ambany additive dia afaka mampitombo ny fahafahana mivoaka avy amin&39;ny 85% ka hatramin&39;ny 90%, izany hoe, ao amin&39;ny rafitra electrolytic ranon-javatra rehetra, solvent, Lithium sira sy additives dia ambany hafanana ho an&39;ny herin&39;ny lithium bateria.

Misy fiantraikany sasany ny endri-javatra, anisan&39;izany ny rafitra ara-materialy hafa. Ny adhesive, raha 20 degre, ny teboka roa dia mety ho voahodina amin&39;ny 70 ka hatramin&39;ny 80 cycles, ary ny takelaka manontolo dia ny sata misy ny tsy fahombiazan&39;ny adhesive, ary tsy misy ny binder linear. ity olana ity.

After the entire system, after the improvement of the positive electrode, the negative electrode, the electrolyte to the binder, the lithium phosphate ion battery monomer does better effect, one is charging characteristics, -20, -30, -40 degrees Temperature 0.5C charging constant current ratio can reach 62.9%, - 20 degree temperature discharge can be released 94%, this is some of the characteristics of the magnification and cycle.
