If this measure is not taken, the stress can lead to crack formation and limit capacity by inducing extreme polarization
[0008] Despite great strides in the field of Si anodes, there are currently no commercial anodes based on Si or Si-containing composites, except for a few recent designs that employ a small amount of Small particles of carbon-coated silicon oxide (SiOx) to slightly increase the gravimetric capacity or pulse power performance of the anode

Abstract

Provided herein is a binder for a battery electrode, binder compositions, electrodes and batteries comprising the same, and methods of preparation thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 754,659, filed November 2, 2018, the contents of which are hereby incorporated by reference in their entirety for all purposes. technical field [0003] The present disclosure relates generally to the field of energy storage. More specifically, the present disclosure relates to binders for battery electrodes, as well as binder compositions, electrodes, and energy storage devices including the same, and methods of making the same. Background technique [0004] Lithium-ion batteries were first commercialized by Sony in 1991 and take their name from graphite (Li x C 6 ) negative electrode (anode) and layered oxide (Li 1-x TO 2 ) between the cathode (cathode) Li + Ion exchange, where T is a transition metal (usually cobalt, but sometimes nickel or manganese). It stores 5 times more energy (≈180Wh / kg) than many older lead-acid batte...
