Customer ServiceLiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM) is a widely used cathode material for lithium-ion batteries (LIBs). However, the poor cycle performance and safety issue remains a huge challenge for its practical applications. Here we show a simple double layer strategy to improve the electrochemical characteristics and safety performance.
The lithium deposit layer in the lithium metal battery often plates on the surface of the lithium negative electrode because of the large current density and uniform ion flux, which makes it easier to generate lithium dendrites. So, the lithium diffusion into the lithium negative electrode can be a good solution to this problem.
The copper coating acts as an upper current collector for a lithium metal, which reduces the local current density by increasing the surface area of lithium deposition, provides more electron transfer for dead lithium, and reduces the loss of battery capacity to a certain extent.
In this work, the effect of various gradient electrodes on the electrochemical performance of Li-ion batteries was investigated both theoretically and experimentally. A modified 2D model was developed to investigate the effects of different electrode structures on the lithiation process.
A reasonable particle distribution is critical for implementing high-energy-density Li-ion batteries, especially at high C-rates. The findings of this work can be used to improve the electrochemical properties of thick electrodes for Li-ion batteries.
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
