Chitosan oligosaccharides: A novel and efficient water soluble binder for lithium zinc titanate anode in lithium-ion batteries

Lithiation and delithiation behavior of sodium lithium titanate anode

“…Recently, Ti-based materials attract extensively concerns for the successful commercialization of Li 4 Ti 5 O 12 [9][10][11][12][13][14][15][16][17][18], which maintains the stable structure during long-term charge-discharge process. Besides, the high electrochemical motivation force (1.55 V vs. Li/ Li + ) of Li 4 [19][20][21][22][23][24] and MLi 2 Ti 6 O 14 (M = Ba, Sr, Pb, 2Na) [25][26][27][28][29][30][31] were successfully synthesized and used as anode materials for lithiumion batteries. It can be concluded that the Li 2 MTi 3 O 8 (M = Zn, Co, Mg, Mn) possesses excellent structural stability during lithiation/ delithiation process.…”

Preparation of a composite anode for lithium-ion battery using a commercial water-dispersible non-fluorinated polymer binder

“…In fact, a large swelling capacity allows the electrolyte to penetrate into the whole composite electrode causing a desquamation of the electrode particles. The swelling character of Pattex PL50, as evaluated in our experimentation, is lower with respect to PVDF [15] (23.9 %). The lower swelling properties can reduce phenomena such as active material particle detachment from the current collector.…”

“…For further increase of time, the amount of swelling remains practically unchanged. It was reported that the swelling properties of binder films can significantly increase the electric resistance of the composite [15]. In fact, a large swelling capacity allows the electrolyte to penetrate into the whole composite electrode causing a desquamation of the electrode particles.…”

MOFs as reactant: In situ synthesis of Li2ZnTi3O8@C–N nanocomposites as high performance anodes for lithium-ion batteries

“…Tibased materials have been intensively researched as promising anodes for their excellent cycling performance and high safety. Especially, the cubic spinel structure lithium zinc titanate (Li 2 ZnTi 3 O 8 ) is an attractive substitute for graphite because of its low cost, non-toxicity, high safety and relatively large theoretical capacity of 227 mA h g −1 [21][22][23][24][25][26][27][28][29][30][31][32][33]. Despite these advantages, the low electronic conductivity and inferior rate capability still hinder the commercial application of Li 2 ZnTi 3 O 8 .…”
