As an energy storage product with stringent requirements for energy density, lightweight design, and safety, the manufacturing process of drone batteries encompasses multiple precise stages, from material preparation to finished product testing. Tag nrho cov txheej txheem yog coj los ntawm electrochemical cov hauv paus ntsiab lus, integrating precision manufacturing thiab nruj zoo tswj kom ntseeg tau tias lub roj teeb ua tau raws li cov qauv tshwj xeeb rau aviation daim ntaub ntawv nyob rau hauv cov nqe lus ntawm kev ua tau zoo, sib xws, thiab kev ntseeg tau.
Cov txheej txheem pib nrog kev npaj ntawm tes. Rau cov lithium polymer hlwb, cov khoom siv hluav taws xob zoo, cov khoom siv hluav taws xob, thiab cov ntawv khi yog thawj zaug tsim rau hauv slurry raws li ib qho piv txwv, sib npaug coated mus rau ib qho txhuas ntawv ci tam sim no, thiab tom qab ntawd qhuav thiab dov los ua ib txheej tuab. Cov electrode tsis zoo yog zoo sib xws rau cov ntawv ci tooj liab siv cov ntaub ntawv xws li graphite. Tom qab ntawd, electrode slitting thiab daim ntawv fabrication yog ua, kom ntseeg tau qhov tseeb qhov tseeb thiab cov npoo zoo. Nyob rau hauv ib lub tshuab ziab khaub ncaws, cov hlwb raug mob los yog stacked, nrog rau cov nplooj ntawv zoo thiab tsis zoo electrode thiab cais pawg los yog muab kauv qhov txhab nyob rau hauv ib qho kev txiav txim predetermined los tsim thawj cell qauv. Cov theem no yuav tsum muaj kev tswj xyuas nruj ntawm cov plua plav thiab noo noo kom tsis txhob degradation ntawm electrochemical kev ua tau zoo.
Tom qab ntawd los ntawm electrolyte txhaj thiab encapsulation theem. Cov lithium polymer electrolyte tau npaj tau ntau npaum li cas rau hauv lub roj teeb ntawm tes, thiab tom qab ntawd muag - pob ntim hauv qab nruj ntsuas kub thiab av noo. Cov txheej txheem encapsulation ntiav cov thermo- xovxwm sealing tshuab kom nruj cov aluminium- zaj duab xis yas, tsim cov qauv kaw. Qhov no tiv thaiv electrolyte leakage thaum tso cai rau qhov chaw me me ntawm lub xov tooj ntawm tes thaum lub sijhawm them thiab tawm, zam kev ua haujlwm tsis zoo lossis kev pheej hmoo kev nyab xeeb los ntawm kev nruj heev.
Tom qab tsim cov cell, cov hlwb mus rau qhov tsim thiab muaj peev xwm muab qhab nia cov txheej txheem. Kev tsim ua kom lub tshuab hluav taws xob cuam tshuam los ntawm qhov pib qis - tam sim no tus nqi - lub voj voog tawm, tsim cov khoom ruaj khov electrolyte interphase (SEI) zaj duab xis. Cov txheej txheem no cuam tshuam rau lub roj teeb lub neej thiab kev nyab xeeb. Capacity grading ntsuas qhov muaj peev xwm thiab kev tiv thaiv sab hauv ntawm cov hlwb raws li cov txheej txheem thiab muab qhab nia raws li kev ua tau zoo, muab lub hauv paus rau kev ntim khoom tom ntej. High- ntim cov khoom sib xws yog qhov tseem ceeb rau kev ua haujlwm ntawm tag nrho cov roj teeb pob; cov hlwb uas muaj qhov zoo sib xws, kev ua haujlwm sab hauv, thiab lub peev xwm yuav tsum tau ua ke kom txo qis kev ua haujlwm tawg thaum caij tsheb kauj vab.
Nyob rau hauv lub roj teeb pob los ua ke theem, cov hlwb yog teem nyob rau hauv series thiab parallel raws li tus tsim thiab kho los ntawm ultrasonic los yog laser vuam siv nickel strips los yog tooj liab-plated nickel connectors, kom ntseeg tau tias tsis muaj impedance thiab txhim khu kev qha conductivity. Tom qab ntawd, lub roj teeb tswj qhov system (BMS) yog kev sib koom ua ke, ua kom tiav kev sib dhos ntawm cov teeb liab tau txais, kev sib npaug ntawm Circuit Court, thiab kev tiv thaiv circuitry. Lub zuag qhia tag nrho yuav tsum muaj kev tiv thaiv casing nrog cushioning thiab ruaj ntseg ntsuas los tiv thaiv kev vibrations thiab shocks thaum lub davhlau. Tom qab casing encapsulation, kev ntsuas hluav taws xob ua ntej thiab kev ntsuas hluav taws xob tiv thaiv qhov ntsuas hluav taws xob tau ua kom paub meej tias tsis muaj kev cuam tshuam luv luv lossis kev pheej hmoo to.
Cov theem kawg suav nrog kev kuaj cov khoom tiav thiab kev kuaj kev laus. Qhov no suav nrog kev ntsuas qhov ntsuas kub ntawm ib puag ncig, kev kuaj xyuas lub neej voj voog, overcharge thiab tshaj -kev ntsuas kev nyab xeeb, thiab kev ntsuas kev poob siab kom ntseeg tau tias cov roj teeb ruaj khov nyob rau hauv cov xwm txheej hnyav. Kev kuaj kev laus tuaj yeem ua rau muaj kev pheej hmoo ua tsis tiav thaum ntxov; tsuas yog cov khoom tsim nyog tuaj yeem mus rau ntim thiab xa khoom.
Zuag qhia tag nrho, kev tsim cov txheej txheem ntawm cov roj teeb drone yog tus cwj pwm los ntawm ib puag ncig huv huv, kev tuav cov khoom zoo, thiab kev sim ntau- qib. It integrates electrochemical preparation, structural engineering, and intelligent control technologies, ensuring high energy density, lightweight design, and high safety for drones through meticulous quality control at every stage.
