The triboelectric
nanogenerator (TENG) has been used to store its generated energy into
lithium-ion batteries (LIBs); however, the influences of its pulse
current and high voltage on LIB polarization and dynamic behaviors
have not been investigated yet. In this paper, it is found that LIBs
based on the phase transition reaction of the lithium storage mechanism
[LiFePO<sub>4</sub> (LFP) and Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> (LTO) electrodes] are more suitable for charging by TENGs. Thus,
the enhanced cycling capacity, Coulombic efficiency (nearly 100% for
LTO electrode), and energy storage efficiency (85.3% for the LFP–LTO
electrode) are successfully achieved. Moreover, the pulse current
has a positive effect on the increase of the Li-ion extraction, reducing
the charge-transfer resistance (<i>R</i><sub>ct</sub>) for
all studied electrodes as well (LFP, LiNi<sub>0.6</sub>Co<sub>0.2</sub>Mn<sub>0.2</sub>O<sub>2</sub>, LTO, and graphite). The excellent
cyclability, high Coulombic, and energy storage efficiencies demonstrated
the availability of storing pulsed energy generated by TENGs. This
research has provided a promising analysis to obtain an enhanced charging
methodology, which provides significant guidance for the scientific
research of the LIBs
