Abstract

Настоящее изобретение может быть использовано для изготовления как защитных подслоев и электродов, так и самих аккумуляторов, для повышения безопасности в процессе эксплуатации. Новизна изобретения заключается в том, что в конструкции электрода используется защитный подслой, который имеет толщину от 25 нм до 10 мкм и выполнен из полимера видавключающего в себя основную цепь и боковые заместители, где R - заместитель из группы -H, -(CH2)nCH3, -O(CH2)nCH3, где n находится в диапазоне от 0 до 12; R1, R2, R3 и R4 - заместители из группы -H, -CH3, -(CH2)4-; M - переходный металл из группы Ni, Co, Cu, Pd. Техническим результатом является электрод, обладающий функциями защиты от перезаряда и вызванного этим разрушения и повышающий безопасность аккумулятора. Изобретение может быть использовано в литий-ионных, алюминий-ионных, натрий-ионных, калий-ионных аккумуляторах и других энергозапасающих элементах.
