“…Low‐frequency mechanical energy is abundant, clean, and renewable and can be harvested from sources such as wind energy, water energy, and ocean wave energy. [ 1 ] Unfortunately, the storage of irregular, intermittent, fluctuating mechanical energy is challenging, which hinders its effective transformation and utilisation. [ 2 ] An ideal method to store mechanical energy is to use it to produce chemical fuels [ 3 ] as they are considered green mechanical energy carriers.…”

Mechanical energy‐induced CO 2 reduction is a promising strategy for reducing greenhouse gas emissions and simultaneously harvesting mechanical energy. Unfortunately, the low energy conversion efficiency is still an open challenge. Here, multiple‐pulse, flow‐type triboelectric plasma with dual functions of harvesting mechanical energy and driving chemical reactions is introduced to efficiently reduce CO 2 . CO selectivity of 92.4% is achieved under normal temperature and pressure, and the CO and O 2 evolution rates reach 12.4 and 6.7 µmol h −1 , respectively. The maximum energy conversion efficiencies of 2.3% from mechanical to chemical energy and 31.9% from electrical to chemical energy are reached. The low average electron energy in triboelectric plasma and vibrational excitation dissociation of CO 2 with low barrier is revealed by optical emission spectra and plasma simulations, which enable the high energy conversion efficiency. The approach of triboelectric plasma reduction reported here provides a promising strategy for efficient utilization of renewable and dispersed mechanical energy.

“…With the escalation of the energy supply crisis and the global epidemic of COVID-19 challenges since the twenty-first century, it is also urgent to speed up the pace of development of power storage materials with excellent electrochemical properties. [1][2][3] Traditional fossil energy has been unable to satisfy the current need for new energy, which directly promotes the development of various new energy storage batteries, fuel cells, and other chemical power sources. Among the development of renewable energy technology-ranging from ordinary lithium-ion batteries (LIBs) required for electronic mobile devices like phones, cameras, and laptops to the power LIBs required for transportation vehicles like electric and hybrid vehicles-LIBs are one of the most successful technologies, and these demands have driven the development of secondary LIBs.…”

Summary The cathode material LiNi0.5Mn1.5O4 has drawn considerable attention for the high‐voltage discharge platform, high power density, and environmental friendliness. However, Mn3+ inside the material leads to the generation of Ni‐O impurities, which contributes to a 4.1 V voltage platform in the charge‐discharge process. To overcome this phenomenon, spinel LiNi0.5Mn1.5O4 was prepared by a high‐temperature solid‐phase method in this article, and samples were annealed after that. Impacts of annealing treatment on properties of LiNi0.5Mn1.5O4 were studied and an effective annealing treatment method was proposed. The charge and discharge test shows that the sample treated by annealing at 600°C for 8 h has the highest capacity (121 mAh/g) and the best cycle capacity retention rate (93.4%). XPS tests showed that the treatment by the annealing process significantly reduced the Mn3+ in the material and eliminated the 4.1 V voltage plateau, which indicates the best annealing process is treating at 600°C for 8 h.
