Embodiment Construction

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0041] The present invention proposes a method for preparing a nanoscale polymer electrolyte for a flexible lithium battery, such as Figure 1 As shown, it includes the following steps:

[0042] (1) Synthesis of crosslinked nano-polystyrene (PS).

[0043] Purified styrene is difficult to store. Commercial products often contain added inhibitors (e.g., trace amounts of hydroquinone). Pure styrene is washed with 10% NaOH solution to remove the inhibitor (tert-butyl catechol), then rinsed twice with water, and then mgSO 4 Carry out drying. Using dichloromethane as the solvent, pure styrene was separated by column chromatography. Remove the solvent and vacuum for half an hour. Pure styrene is stored at 0 °C.

[0044] Chloroform is added to vinyl anise ether, the mixture is washed with 10% sodium hydroxide, and the yellow organic matter is rinsed twice with water, wi...

Description

Technical field [0001] The present invention relates to the field of lithium-ion batteries, in particular a method for preparing a nanoscale polymer electrolyte for flexible lithium batteries. Background [0002] Pressure to reduce carbon emissions, global warming and over-reliance on fossil fuels are several of the factors that make electric and hybrid vehicles (EV / HEV) more attractive alternatives than burning fossil fuels. Lithium-ion batteries have a higher power-to-weight ratio (2.59MJ / Kg) than lead-acid batteries. In addition, lithium-ion batteries have good versatility in many other applications, such as computers, mobile phones, cameras, camcorders, and medical devices. However, current lithium-ion batteries have to overcome some limitations before they can be used on a large scale. Three of the most important challenges are energy density, cost and operational safety. Electrolyte is the second most expensive (after cathode) component in lithium-ion batteries. Battery co...
