Inkqubela phambili yezobuchwepheshe kwiibhetri ze-lithium-ion iye yacotha.Okwangoku, iibhetri ze-lithium-ion ziphezulu kakhulu kune-lead-asidi kunye ne-nickel-metal hydride ibhetri ngokwemiqathango yobuninzi bamandla, iimpawu zokushisa eziphakamileyo kunye neziphantsi, kunye nokusebenza kokuphindaphinda, kodwa kusenzima ukuhlangabezana nemfuno ekhulayo ngokukhawuleza yeemveliso ze-elektroniki. kunye nezithuthi zombane.Kwiminyaka yakutshanje, abaphandi baye basebenza ekuphuculeni ubuninzi bamandla (i-volume-to-volume ratio), ixabiso, ukhuseleko, impembelelo yendalo kunye nobomi bovavanyo lweebhetri ze-lithium-ion, kwaye baqulunqa iintlobo ezintsha zeebhetri.Kodwa i-Patherini ithi itekhnoloji yebhetri ye-lithium-ion yesiko ngoku isondele kwi-bottleneck, kwaye indawo yokuphucula ngakumbi inomda.
Iingcali zenzululwazi ngoku zisebenza kwiibhetri ezintsha ezinokugcinwa kwamandla amaninzi kunye nexesha elide lokuphila, ngakumbi kwiinkalo ezahlukeneyo, kuba akukho nanye ifanelekileyo kuwo wonke amasimi. uphuhliso lobuchwephesha obutsha.Zikhaphukhaphu kwaye zihlala ixesha elide, kwaye zinexabiso elingenakuthelekiswa nanto ekuphuhliseni iteknoloji yabathengi bedrone.
Kungekudala, izazinzulu zaseTshayina zavelisa ibhetri ye-lithium-ion enokusetyenziswa kwi-70 degrees Celsius, enokuthi isetyenziswe kwiindawo ezibanda kakhulu kunye nakwindawo engaphandle, evakala ngathi yimini eyoyikisayo.Ngokutsho kwabaphandi, entsha ibhetri ayibizi kwaye ihambelana nokusingqongileyo, kodwa ixesha elibalulekileyo lokuba lifumaneke ngokurhweba kukuba ubuninzi bayo bamandla buphantsi kakhulu ukufanisa iibhetri ze-lithium-ion zendabuko.
Kutshanje, iteknoloji entsha kwicandelo lebhetri.Iqela lophando kwiYunivesithi yaseHarvard liphuhlise uhlobo olutsha lokuhamba kwebhetri usebenzisa i-electrolyte engeyona ityhefu, i-noncorrosive, i-pH-neutral, kwaye inobomi obungaphezu kweminyaka eyi-10. Iqela ithi ibhetri yokuhamba ingasetyenziswa kuphela kwii-smartphones, kodwa nakwizicelo zamandla amatsha, kubandakanywa amandla avuselelekayo, ngokhuseleko olungcono kunye nokuphila ixesha elide kuneemveliso zebhetri zangoku, iqela lathi.

Olunye uhlobo lwebhetri luphinde lwenze ukuphumelela kwezobuchwepheshe.Uhlobo olutsha lwebhetri yesimo esiluqilima luphuhlisiwe.Ibhetri yesimo esiqinileyo incinci kuneebhetri ze-lithium-ion zendabuko, i-electrode eqinile kunye ne-electrolyte eqinile, kunye nokuxinwa kwamandla aphantsi, amandla aphezulu. Ubuninzi, amandla afanayo, umthamo webhetri yesimo esiqinileyo incinci kuneebhetri ze-lithium-ion eziqhelekileyo.
