Lithium bis(oxalato) borate was investigated as an additive for the stabilization of a high-voltage cathode electrolyte interface (57). It has been found that the electrochemical performance of Li/LiNio.5Mni.504 cells with a hthium bis(oxalato) borate additive was improved at 60°C. 

It has been reported that LMO particles coated with either borate glass Li20-2B2O3 (LBO) or with fluorine exhibit good high-temperature electrochemical performance. LBO-coated LMO electrode via solutimi method has an excellent cycling behavior (112 mAh g ) without any capacity loss even after 30 cycles at 1C rate [63]. Huoride is also used to coat LMO to improve its cyclabiUty because it is very stable even in HF. Lee et al. [64] reported that the BiOF-coated spinel...

Besides the common plasticizers mentioned in Table 11.2, borate can also be used as a plasticizer. After copolymerization of the two PEG methacrylate (PEG-M) monomers shown in Figure 11.18, a PEG borate ester (PEG-BE) or its mixture with PC is added. As the results show in Figure 11.19, the ionic conductivity of the prepared cross-linked gel polymer electrolyte is highest with the PEG-BE-PC mixture and is consistent with the Arrhenius equation. Its thermal and electrochemical stability and mechanical performance are good, and it has excellent cycling performance from room temperature to 65 C [14].
