Embodiment

[0062] Example - Manufacture of Lithium Storage Battery Using Hybrid Polymer

[0063] Step 1: Synthesis of Li-ion-conducting hybrid polymer binder

[0064] In a 250 mL flask, 152 g (0.29 mol) of 2-methoxypolyethylenepropoxytrimethoxysilane and 2.634 g of lithium hydroxide were stirred (mixture 1).

[0065] In parallel, 23.6 g (0.1 mol) of 3-glycidylpropoxytrimethoxysilane and 140 g of diethyl carbonate were weighed into a 100 mL flask, to which 2.7 g (0.15 mol) of distilled water were added (Mixture 2) . The mixture was stirred.

[0066] After reaching the clear point of mixture 2, a homogeneous mixture 1 was added thereto.

[0067] After a few days, the solvent was centrifuged at 40°C and 28 mbar.

[0068] Step 2: Coating the battery material with a hybrid polymer binder

[0069] In a 1L flask, weigh 30 g of battery material particles (such as Li(Ni, Co, Mn)O 2 particle). Subsequently, 400 g of dimethyl carbonate and 3 g of the hybrid polymer binder from step 1 (op...

Abstract

The invention relates to a lithium battery or a combination thereof with a double-layer capacitor, said battery being characterized by a solid electrolyte or gel electrolyte and a binder made of inorganic-organic hybrid polymer. By means of the new binder concept presented here, it is possible to revolutionize the contacting of the individual components in said batteries and thus to enable a fundamental improvement of the ion transport. Associated therewith is a new, fast, simple, and flexible production method for lithium batteries that optimizes said batteries in regard to safety, stability, environmental friendliness, and performance.

Description

technical field [0001] The present invention relates to a lithium accumulator or its combination with a double layer capacitor, said lithium accumulator is characterized by a solid material electrolyte or a gel electrolyte and a binder made of an inorganic-organic hybrid polymer. The contacting of individual components in these batteries can be revolutionized by the novel binder concept presented here, enabling radically improved ion transport. Relevant to this is a novel, fast, simple and flexible method for producing lithium accumulators which optimizes these with regard to safety, stability, environmental friendliness and efficiency. Background technique [0002] To date, the transport of lithium ions (besides the conductivity of the active material itself) across the electrodes of many different rechargeable lithium battery variants has been possible, notably by tuning the specific porosity and liquid electrolytes that infiltrate these pores. [0003] The problem with t...
