Herein, the polypyrrole (PPy) with highly conductive and adhesive features is first introduced to fasten the liquid metal nanoparticles (gallium-tin alloy, EGaSn) in the integrated electrode and applied as the anode for lithium-ion batteries.
Surprisingly, the full cells consisting of GaIn alloy anode with LiFePO 4 (LFP) and Na 2/3 [Ni 1/3 Mn 2/3]O 2 (NNMO) as cathode showed stable performance with 96.9% capacity retention per hundred cycles and 96.1% per decade of cycles, respectively. (A) GaIn liquid metal nanoparticles (LMNPs) for LIBs and sodium-ion batteries.
The fluidity and metallic conductivity of gallium-based alloy provide a research possibility for the exploration of self-healing electrodes for LIBs, such as gallium (Ga), gallium-indium alloy (EGaIn), and gallium-tin alloy (EGaSn) , , .
Owing to the feature, there was no Al dendrite, corrosion or pulverization observed on the liquid Ga negative electrode during alloying/dealloying process or even after long time cycles. Compared with the conventional Al negative electrode, the liquid Ga negative electrode delivered enhanced stability and cycle life.
As a result, the customized anode displays superior cycling stability (499.8 mAh g −1 after 500 cycles at 1.0 A g −1) and rate capability (350 mAh g −1 at 2.0 A g −1 ). This work enriches the electrode engineering technology of liquid metal nanoparticles and opens up a new way to customize the self-healing anode for lithium-ion batteries.
