    Thought it would be good to put the patents out there..... I had not seen anyone post these, so a little dump below on these for anyone looking to do some reading or read how our IP is protected.

    Polycrystalline particulates for rechargeable battery electrodes
    Patent Link
    CA CA3069168A1 Mark N. Obrovac Novonix Battery Testing Services Inc. Priority 2019-03-27 • Filed 2020-01-22 • Published 2020-05-18
    Improved polycrystalline particulates and methods of preparation are disclosed, particularly for use as a lithium insertion cathode for a rechargeable lithium battery. The surface layer of the polycrystalline particulates is smoothed, for instance by mechanofusion. Coating layers that are desirably smoother can then be applied, also for instance by mechanofusion. Such polycrystalline particulates, both with and without coating layers, show improved performance in battery applications.

    Electrochemically active dispersions and composites for rechargeable battery anodes
    Patent Link

    WO WO2020131429A2 Mark Obrovac Novonix Battery Testing Services Inc. Priority 2018-12-19 • Filed 2019-12-06 • Published 2020-06-25
    Particulate dispersions and composites are disclosed which comprise graphite and alloy particles comprising both active (e.g. Si) and inactive phases with regards to electrochemical activity with alkali or alkaline earth metals (e.g. lithium). The alloy particles are highly dispersed as primary particles with graphite particles and/or within the graphite particles' matrix in a novel manner and can be prepared using simple mechanofusion dry processing methods. In the composites prepared, the alloy particles are essentially embedded between layers in the graphite matrix. Improved performance can be obtained when these dispersions or composites are used in lithium insertion anodes for rechargeable lithium batteries, including high capacity, good cycling performance, and rate capability.

    Thermal feature analysis of electrochemical devices
    Patent Link
    WO US JP DE US20180074132A1 Ryan Day Ryan Day Priority 2015-03-18 • Filed 2016-03-14 • Published 2018-03-15
    Methods, devices, and systems are disclosed for determining certain thermal properties of electrochemical devices that contain an electrolyte. From these properties, useful information can be determined about the electrical device. For example, the state-of-health of lithium ion batteries and other electrochemical devices can be determined.

    Analysis of thermal characteristics of electrochemical devices
    Patent Link
    WO US JP DE DE112016000894T5 Jeff Dahn Jeff Dahn Priority 2015-03-18 • Filed 2016-03-14 • Published 2017-11-16
    Methods, apparatus, and systems for determining certain thermal properties of electrochemical devices containing an electrolyte are disclosed. From these properties, useful information about the electrochemical device can be determined. For example, the health of lithium ion batteries and other electrochemical devices can be determined.
