Abstract: The present invention provides a thermally-decomposable consolidated polymer particle encapsulated-electrode for a lithium-ion battery. The electrode includes polymer particles including at least one connection unit and at least one crosslinker in an amount of approximately 40% to 98% by weight and at least one binder material in an amount of approximately from 2% to 60% by weight. The consolidated crosslinked polymer particle coating results in a porous structure encapsulating the electrode. The pressure resistance of the consolidated crosslinked polymer particle coating ranges approximately from 0.5 to 8 MPa and the consolidated crosslinked polymer particle coating is decomposed to release a non-flammable gas and phosphorous-containing molecules so as to prevent thermal runaway at a temperature approximately from 300° C. to 500° C.

Abstract: A solar-powered position tracker includes a load including one or more of a GPS module, a GPS antenna, a GSM module, or a GSM antenna. The load is powered by a rechargeable battery, which may be charged by one or more of a non-rechargeable primary battery and a solar cell. The solar-powered position tracker includes a battery management system for powering the position tracker by controlling the solar cell, rechargeable battery and the non-rechargeable primary battery. The two-stage battery management system charges the rechargeable battery in two stages and includes a solar management and protection circuit interconnecting the solar cell, and the rechargeable battery. The battery management system is configured to execute a charging process for recharging the rechargeable battery from solar cell and protect the rechargeable battery under a high pulse current discharge process to meet a high current or high pulse current discharge demand by the load.
