“…However, the loading of binders should also be decreased to maintain the practical application. Based on studies on conductive-type binders used for graphite anodes, [63][64][65] further research could be focused on conductive Li substituted polymers, which could provide more freely moving Li + . Free Li + could fast transfer from the polymer chains to active materials which could shorten the pathway of Li + to the surface of active materials.…”

Summary In this review, we highlight recent achievements of polymer binders used for Si‐based anodes in Li‐ion batteries. We classify the polymer binders, depending on their polymer structures and the function on performances of Si‐based anodes, into 3 types: cellulose‐type, conductive‐type and self‐healing‐type binders. The relationship between polymer structures and enhanced electrochemical performances of Si‐based anodes is discussed in details. We investigate how the binders make an extraordinary improvement on the specific capacity, cycling stability and rate performances of Si‐based anodes. The reasons of the noticeable effect on Si‐based anodes especially the controlling of swelling during cycling are also researched. In a word, the main aim of this review is to analyze recent research achievements and propose perspectives of polymer binders used for Si‐based anodes in promising Li‐ion batteries.

“…Figures and a show the design and structure of the PSBA-Li with more Li + in molecule chains. More Li + could enhance conductivity and transfer at the interface between the cathode and the electrolyte to shorten the distance to LiFePO 4 particle surfaces − to a degree, which is beneficial for cycling and rate performances. Moreover, the limited addition amount of the PSBA-Li can improve the energy density for further application.…”

“…The unlithiated PSBA-H electrodes (Figure b) present obviously low capacities compared to PSBA-Li electrodes for the function of Li + . More Li + could enhance conductivity and shorten the distance to LiFePO 4 particle surfaces. − When rates increased from 0.5C to 2C, capacities of PSBA-Li cathodes decrease due to the poor conductivity of LiFePO 4 cathodes, which hinders the lithiation/delithiation process. The PSBA-Li cathode presents relatively stable cycling performances at various rates compared with PVDF cathodes with rapid capacity fading attributed to weak van der Waals forces. , After 200 cycles, capacity retentions of PSBA-Li electrodes are 108.5%, 103.6%, and 114.9% at the rates of 0.5C, 1C, and 2C, respectively, compared to that of the PSBA-H (1.5%) electrode with 103.9% (0.5C) and the PVDF electrode with 7% (0.5C), which is about 15 times higher.…”

The poor conductivity of olivine structure LiFePO4 led to inevitable hindered electrochemical performances and restricted their uses in Li-ion batteries. To overcome the problem, introduction of conductive agents that bind with LiFePO4 active material is a universal solution. In this paper, a novel waterborne lithiated ionomer binder (PSBA-Li)for Li-ion batteries was originally designed and assembled with the low addition of 1.5% of a LiFePO4 cathode, showing a high areal capacity of 2.0 mAh cm–2. During lithiation/delithiation processes, PSBA-Li provided more Li+ ions, resulting in enhanced conductivity, which led to better performances. After 200 cycles, the PSBA-Li cathode based battery maintained stable cycling performances with retentions of 108.5%, 103.6%, and 114.9% at rates of 0.5C, 1C, and 2C, respectively, in contrast with a commercially used PVDF-cathode with a retention of only 7% (0.5C). The rate performance of the PSBA-Li cathode is higher than that of the PVDF-cathode, which shows almost no capacity at high rates. For contrastive analysis, SEM indicates a well integrity PSBA-Li cathode structure after cycling. On the contrary, active materials of PVDF-cathode separate from the aluminum foil after cycling. It is believed that the PSBA-Li has significant potential for further application for LiFePO4 cathodes in Li-ion batteries.

“…This will lead to the anode being corroded by the electrolyte and thereby to a lower Coulombic efficiency. 5 On the other hand, the Li metal was observed to grow in a dendritic form during the cycling process, leading to severe safety issues that hinder the commercialization of Li metal batteries (LMBs). 6 In traditional liquid LMBs, serious formations of Li dendrites and "dead Li" usually take place on unprotected metallic Li after the plating/stripping cycles (Scheme 1a).…”

The Li metal anode is considered one of the most potential anodes due to its highest theoretical specific capacity and the lowest redox potential. However, the scalable preparation of safe Li anodes remains a challenge. In the present study, a LiF-rich protection layer has been developed using self-driven chemical reactions between the Li3x La2/3–x TiO3/polyvinylidene fluoride/dimethylacetamide (LLTO/PVDF/DMAc) solution and the Li metal. After coating the LLTO/PVDF/DMAc solution to Li foil, PVDF reacted with Li spontaneously to form LiF, and the accompanying Ti4+ ions (in LLTO) were reduced to Ti3+ to form a mixed ionic and electronic conductor Li x LLTO. The protective layer can redistribute the Li-ion transport, regulate the even Li deposition, and inhibit the Li dendrite growth. When paired with LiFePO4, NCM811, and S cathodes, the batteries have demonstrated excellent capacity retention and cycling stability. More importantly, a volumetric energy density of 478 Wh L–1 and 78% capacity retention after 310 cycles have been achieved by using a S/Li x LLTO-Li pouch cell. This work provides a feasible avenue to provide large-scale preparation of safe Li anodes for the next-generation pouch-type Li–S batteries as ideal power sources for flexible electronic devices.
