Lithium iron phosphate ion battery refers to a lithium ion battery with lithium iron phosphate as a positive electrode material. Izinto ezilungileyo ze-electrode zebhetri ye-lithium-ion zibalulekile kwi-lithium cobalt organte, i-lithium manganate, i-lithium nickel acid, izinto ezintathu-dimensional, i-lithium iron phosphate, njl. Phakathi kwabo, i-lithium iron phosphate yinto efanelekileyo esetyenziswa ngoku kwiibhetri ezininzi ze-lithium-ion.

I-Lithium iron phosphate ion ibhetri ipakethi kufuneka inyuse, iphucule ibhetri ye-lithium ukusebenza kobushushu obuphantsi. 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, ukuqhuba kakubi, ukucotha kwe-lithium ion ukusasazwa kwesantya.

Xa ixabiso eliphezulu kunye nokukhutshwa, inani langempela liphantsi, le ngxaki yinto enzima yokukhawulela ukuphuhliswa kwe-lithium iron phosphate industry. I-lithium iron phosphate ayinalo uluhlu olubanzi lwezicelo kade, lo ngumba obalulekileyo. I-3, impembelelo yezinto eziphathekayo, i-lithium iron phosphate positive electrode ngokwayo ihlwempuzekile, kwaye i-polarization ixhomekeke kwi-polarization, ukunciphisa umthamo womthamo; isibonda esibi sibalulekile kwintlawulo ephezulu yokushisa, kuba ichaphazela ingxaki yokhuseleko; Enye, inokunyusa i-viscosity kwiqondo lokushisa eliphantsi, i-lithium ion impedance yokufuduka iya kwanda; eyesine ngumdibanisi, kwaye le nayo inkulu ngokwentelekiso.

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. Ngokumalunga ne-positive, ngoku i-nanomechanically, ubungakanani bayo bamasuntswana, ukuxhathisa, kunye nabavelisi be-AB planar axis baya kuchaphazela iimpawu zobushushu obuphantsi bebhetri. Iinkqubo ezahlukeneyo zineempembelelo ezahlukeneyo kwi-electrode elungileyo, kunye neempawu zokukhutshwa kobushushu obuphantsi bebhetri eyenziwe yi-100 ukuya kuma-200 nano-particle ububanzi be-phosphate, enokukhulula i-94% kwi-degrees -20, eyi-particle diameter ye-nanofence eyenza mfutshane indlela yokufuduka, Ikwaphucula ukusebenza kobushushu obuphantsi kunye nokukhupha, kuba i-lithium yokukhupha i-lithium ihambelana ne-electrophosphate.

Ukuqwalasela iimpawu zokutshaja kwi-electrode engalunganga, ukutshaja kweqondo lokushisa eliphantsi kweebhetri ze-lithium ion kubalulekile, kubandakanywa ubungakanani be-particle yesayizi ye-particle kunye ne-pitch ye-electrode engathandekiyo, khetha i-graphite yokwenziwa kwe-electrode emithathu eyahlukileyo njenge-electrode engalunganga ukuze ufunde isithuba esahlukileyo somaleko kunye nobukhulu be-particle size pair Isiphumo seempawu. Ukusuka kwizinto ezintathu, igraphite yengqolowa yomaleko inkulu, ukusuka kwi-impedance, i-impedance yomzimba kunye ne-ion impedance impedance incinci. Ngokumalunga nokutshaja, ipakethe yebhetri ye-lithium-ion ayinkulu kwiqondo lokushisa eliphantsi ebusika, kwaye kubalulekile ukuba intlawulo yokushisa ephantsi.

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. Esi siqwenga se-electrolyte, kwi-degrees -20, -30 degrees, i-electrolyte, ukwanda kwe-viscosity, kunye nokuwohloka komsebenzi.

I-Electrolyte evela kwiinkalo ezintathu: i-solvent, ityuwa ye-lithium, i-additive. I-solvent inefuthe eliphantsi lokushisa kwe-lithium iron phosphate ion battery packs ukusuka kwi-70% ukuya ngaphezu kwe-90%, kunye namanqaku angaphezu kweshumi elinesibini; okwesibini, iityuwa ze-lithium ezahlukeneyo zinempembelelo ethile kwiimpawu zokushisa okuphantsi kunye nokukhutshwa. Silungise inkqubo ye-solvent kunye nesiseko setyuwa ye-lithium, i-additive ephantsi yokushisa inokunyusa umthamo wokukhupha ukusuka kwi-85% ukuya kwi-90%, oko kukuthi, kuyo yonke inkqubo ye-electrolytic liquid, i-solvent, ityuwa ye-lithium kunye ne-additives yiqondo lokushisa eliphantsi kumandla ethu ibhetri ye-lithium.

Iimpawu zineempembelelo ezithile, kubandakanywa nezinye iinkqubo eziphathekayo. I-Adhesive, kwimeko ye-degrees ezingama-20, amanqaku amabini mhlawumbi aqhutywe yi-70 ukuya kwi-80 imijikelezo, kwaye ipleyiti yonke yimeko yokungaphumeleli kwe-adhesive, kwaye i-binder yomgca ayikho. le ngxaki.

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.
