A new design for Si wears double jackets used as a high-performance lithium-ion battery anode

Recent Advances in Silicon‐Based Electrodes: From Fundamental Research toward Practical Applications

“…While the previously discussed nanostructures have made improvements for suppressing the huge volume expansion of Si-based materials, swelling-induced active material delamination from the current collector and electrode instability remain critical challenges for Si anodes. [262,263] In order to meet the commercial request, the tap density of Si-based electrode should reach ≈1.65 g cm −3 , while electrode swelling is limited to 10%. The concept of thickness swelling is an important factor for electrode design and is usually ignored for material design.…”

Si/FeSi2 Nanoparticles Prepared by Thermal Plasma with Stress‐releasing Effect for Li‐ion Storage

“…Besides, the R SEI represents the resistance of lithium ions entering the SEI layers [27,29,61] . There is a sloping line in low‐frequency region called Warburg resistance, which represents the lithium‐ion finally diffuse into the interspace of the electrode materials [64,65] . The R ct value of pure Si/FeSi 2 NPs electrodes is 129 Ω before cycle.…”

Rational Design of Core‐Shell Structured C@SnO2@CNTs Composite with Enhanced Lithium Storage Performance

“…[3,4] Thereby, developing and searching for advanced anode materials with high specific capacity as candidate is extremely urgent. [1,5,6] So far, many kinds of anode materials have been used in LIBs such as nanosized carbons, [7] alloys, [8,9] metal oxides, [10][11][12][13] metal sulfides [14][15][16][17][18] and metal selenides. [19][20][21][22] Among them, SnO 2 , which is well documented in several works, is regarded as a promising candidate for commercial graphite anode because of much higher capacity (1494 mAh g À 1 ), low working potential, chemical stability as well as nontoxicity.…”
