Purškiamieji elektros dažai bet kurį paviršių paverčia į bateriją
Ličio jonų baterijos veikia sudedant aktyviuosius medžiagų sluoksnius. Nešiojamajame kompiuteryje ar mobiliajame telefone šie sluoksniai yra sudedami į bloką, tačiau naujasis procesas galėtų padaryti tai, kas atrodo neįmanoma: paversti bet kurį paviršių baterija tiesiog ant jo užpurškus specialių dažų.
Rice universiteto mokslininkai išbandė įvairius dažus, kol jie nustatė, kokie dažai galėtų veikti kaip ličio jonų baterijos sudedamosios dalys: du srovės imtuvai, katodas, anodas ir polimero separatorius. Sluoksniai gali būti užpurkšti ant bet kokio paviršiaus ir baterija bus visiškai įkrauta.
Mokslininkai, norėdami išbandyti savo naująjį atradimą, jį purškė ant plieno, stiklo, keramikinių vonios plytelių ir panašiai. Dažai, kurie buvo užpurkšti ant vonios plytelių, palaikė bateriją pastovia 2,4 V srove, o tai yra pakankamai šviesos galios, leidžiančios šviesos diodams veikti net šešias valandas.
