It must keep the positive and negative electrodes apart to prevent short circuits, while simultaneously allowing lithium ions to pass through during charging and discharging. It also has to survive […]ScienceTecTechnology and EngineeringTechnology and Engineering$advanced battery separator materials9Core-shell nanofiber separators for lithium-ion batteries(electrolyte-permeable battery separators#flexible electronics battery safety1heat-resistant and stretchable battery components'innovations in battery separator design+mechanical durability of battery separators0nanofiber membrane technology for energy storage$next-generation energy system safety/preventing internal shorts in lithium-ion cells*thermal stability in lithium-ion batteries"wearable device battery componentsC    !'"#%%%),($+!$%$C   $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$"? !1"AQaq2B#$Rrb34CDS/!1A"Q2aB#$Rb ?=1;S遚ӝ5yMQՍo{KE'ʭJH[^bB }_Z@ie8앂gBv2Qݐ8v{7\**uY&Yv;JSpzuN[jPJ{!$kJ0;jBБ˓=Z] ߒ ^ vPrw8RW^x4T3JW*ZC4~R){/uqle(NZߎ;td77(B/ҭqQ#kkk6㱢-"| 8xI=hLO7'yٖJJ}j^ lRTD=(26lP:YooK,XJ@֫)O-6 GqH'bXq"-- zz&R䢎Bʩ1r]yΥ I5E\WXY8/qAh0~{|RPop"2R < Җ):r)M-(c4w\d=Y;*B;Zo䧸f[QĖv"7mUp$>xD4h \GRp6ITdpUGt~>.D~c9mktǗ>9 Nz5mKZ[xÒsv)9=,?Г}c"j+YD[yH?#DzBw[V422p u#c?>ۯfmش1Ԭ.`8*S5 lWF XZV CtDd 2ۄғ[D)utWb}h"pX+0=ڶx>t5-v}Qo\9iyz=YqiP 7e/L7d7-Mr CKQ"]5n+ៗh8^$6ѓIuR PHϭJQ";*Wt3\Q\9Z`z-_^[%m!GS}Vu^HSJqKͬ¸yJ9[P-W1U6ЂIRWI 6vnIw-h W'yz.E{ !CȊObvu#f#;$֏>۱S ncַ1)By!JIGlnwJO<62xuװ&9+Yxt]@_թ!F+;R@[j>gJU҉l'㔧Foy2LU$Ĥ)xme*O?4۰TrusiNܟtJ@8+͆7B[ȱ3)HR]W y>ݾ iղR)L䅕BqM-`jOm!nq<( ^vY T5w7$)tJFk*u33U}z'rTsPäWy%) 0-vwf!7q# OU%_N9Ҝdϯ֩˖ɔ64 )x-qeUdƲ;(OI3imrO6}q=y1ʏtIټHmܓ5 WôV+I%-{0,mA-O\ iNo(LCh#8}ji.%~ーnPVNB}~Ǝ9#q8R;rIץT ro揺W|Ғw82J8GgUU4VB#Dw'&*hVHǕ!^ JPگGQX18 1r&(ե;;*\BirUݶנf- JfKV_o^h Ci!X'\|7}N/tiu0bgj K<2&w"Kl K'8/8}p<=FmjG| Ze2v9ZI[K 6*?jh i`sn:w#Te[pC{:ցq+h<8g%yCijumJPⷾtmN8ҷmG5rSȒPeH8: kN9s% ^nva!wYtɌO=U!-aDt=GZWN8KJ<FVoNb |gJ 7zgB_údY愄au!\61N.gˑ;P0NgW 1dQzCZ R&![zBB HjNExult!yVrV _ZKe%0dQʕAmD?]|rD4v[H$X| +wχ%9C,IĂ@W GJt11mN^@n%7~='cMFjz.6)Lw3`e'<t\ŎoC6*J<DZ\f3Gp,[Be%)Kq$g>|HcAB=hO='Rhw&//p*m A&zd$pHGnxPAnzj G XI>د]Oĺʝ}`'< 0+BT[Hi8.s΄nZͤ"+].܀c>cDGo*K$Ӵ=pt6fai\2}+-Kir߾r[(Y>cP㚸—q U % k`\[Z҇Μ\FMԦkLg ivGZʘ!yͧ.F-O$eImҤ{'߯ޙz3^tR%8G*AWxe]}sLIM3 d$r@m/{~M[rw(]>ŜPvdiCV (T6&[J!n2QK)Zr# LMCNRpkNƼ.xX ߚ(Aai%!PllyS"W5ИP$':Kiub[HRBR#<#^k7 $'`PZZ>y26Qo+RGDIG|M+ycͰaNekHfFe6- sb^,ˌhÖ㙸+.u.'" yΰZq)i C& TrMuznJ"m{NfLi$җ x}Z,R&A 'FL)iJ'ΗZlKmXqVٛmܜ+z:ՄŴHKmhPhb\CN8 bm\8$2I dLN#|ro F>Ơ:RE;sRBP8J4#-~f9HIKnqED֩b1gX.N(%ԶE.$zSH*RfæX 3W\mW]UoLC庆7i]̾TX(ODj&ȹ<)o*rNqҘ\tI!uJRWwm6J@FZǓ=jT[E=k J'SWS_mRfօ<)N-AVG5*SB_U'NqrA\(*RSB4JBNH (B2r=jT(Zt{kҽ<`'*TQ] 3V/R7Z RJBj
