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.The present invention can be used for the manufacture of both protective sublayers and electrodes, and the batteries themselves, to increase safety during operation. The novelty of the invention lies in the fact that a protective sublayer is used in the design of the electrode, which has a thickness of 25 nm to 10 μm and is made of a polymer that includes the main chain and side substituents, where R is a substituent from the -H group, - (CH2) nCH3 , -O (CH2) nCH3, where n is in the range from 0 to 12; R1, R2, R3 and R4 are substituents from the group -H, -CH3, - (CH2) 4-; M is a transition metal from the group Ni, Co, Cu, Pd. The technical result is an electrode with functions of protection against overcharging and the resulting destruction and increasing the safety of the battery. The invention can be used in lithium-ion, aluminum-ion, sodium-ion, potassium-ion batteries and other energy storage elements.
