💡 Novelty & Significance:
A single multifunctional additive (TDTB) integrates B-O, Si-O, benzene, and -CF3 groups to simultaneously stabilize high-voltage LiCoO2 cathodes and graphite anodes via preferential decomposition, forming robust CEI/SEI layers. This dual-interface strategy enables 90% capacity retention over 800 cycles and wide-temperature adaptability, offering a molecular-design route toward long-life, high-energy-density lithium-ion batteries.
