Abstract
A capacitor-assisted battery includes an electrolyte having a lithium-ion conducting component and one or more additives. The one or more additives include a first additive that includes 3-trimethylsilylphenylboronic acid and a second additive that includes succinic anhydride. The capacitor-assisted battery includes an electrode having an electroactive material and a capacitor material. The electroactive material has a first coating defined thereon, and the capacitor material has a second coating defined thereon. The first and second coatings are defined by the first and second additives. The first coating is a substantially continuous coating that covers greater than or equal to about 80% of a total exposed surface area of the electroactive material. The second coating is a discontinuous coating covers greater than or equal to about 20% to less than or equal to about 80% of a total exposed surface area of capacitor material.
