Embodiment Construction

[0190] The present invention relates to a phase change material (PCM) comprising a tetrafluoroborate anion in which a solid-to-solid phase transition exists; and wherein the PCM has a phase transition in the following intervals: about -270°C to about 3,000°C; about -50°C to about 1,500°C; about 0°C to about 1,000°C; about 0°C to about 500°C; about 100°C to about 400°C; about 150°C to about 300°C; about 200°C to about 300°C; °C; or from about 270°C to about 280°C.

[0191] Accordingly, the present invention relates to phase change materials (PCMs) comprising at least one or more (eg mixtures) tetrafluoroborate salts that undergo a solid-to-solid phase transition.

[0192] In particular, the present invention relates to phase change materials (PCM) comprising at least one or more (eg mixtures or series) of tetrafluoroborate salts, wherein at least one tetrafluoroborate salt having a solid-to-solid transition is present.

[0193] Tetrafluoroborate may contain tetrafluoroborate (...

Abstract

There is herein described phase change materials (PCMs) comprising at least one or a plurality (e.g. a mixture) of tetrafluoroborate salts that are capable of undergoing a solid-to-solid phase transition. In particular, there is described phase change materials (PCMs) comprising at least one or a plurality (e.g. a mixture) of tetrafluoroborate salts where there is at least one tetrafluoroborate salt or a plurality of tetrafluoroborate salt which have a solid-to-solid phase transition. The tetrafluoroborate salt may comprise at least one anion or a plurality of the same or different anions of tetrafluoroborate (e.g. BF4-). The PCM may have a solid-to-solid phase change in the region of about -270 DEG C to about 3000 DEG C, about -50 DEG C to about 1500 DEG C, about 0 DEG C to about 1000 DEG C, or about 0 DEG C to about 500 DEG C temperature range.

Description

technical field [0001] The present invention relates to phase change materials (PCMs) comprising at least one or more (eg mixtures) of tetrafluoroborate salts capable of undergoing a solid-to-solid phase transition. In particular, the present invention relates to phase change materials (PCMs) comprising at least one or more (e.g. mixtures) of tetrafluoroborates, wherein at least one tetrafluoroborate or more Tetrafluoroborate. Tetrafluoroborate may contain tetrafluoroborate (e.g. BF 4 - ) of at least one anion or a plurality of the same or different anions. The PCM can have a solid-to-solid phase transition in the temperature range of about -270°C to about 3,000°C, about -50°C to about 1,500°C, about 0°C to about 1,000°C, or about 0°C to about 500°C. Background technique [0002] Phase change materials (PCMs) are materials that have a high latent heat associated with phase transitions and have potential for use in energy storage applications, among others. [0003] PCMs...
