Abstract: Various embodiments provide a battery and a method for manufacturing the battery, an apparatus of manufacturing the battery and an electricity-consuming device. In some embodiments, the battery includes a battery cell; a case assembly configured to accommodate the battery cell and including a first portion, in which the first portion is arranged at least one side of the battery cell in a first direction; and a first bonding member, in which at least part of the first bonding member is filled between the first portion and the battery cell and bonds the first portion and the battery cell. A first gap is formed between the first portion and the battery cell, and the first gap is configured to release an expansion stress when the battery cell expands. The solutions provided by the embodiments of the present disclosure can improve the energy density and safety of the battery, and prolong the service life of the battery.

Abstract: The document discloses a pre-distorter, which comprises: a pre-distortion module, which is configured to pre-distort a plurality of baseband input signals by an equal number of pre-distortion functions to obtain an equal number of pre-distorted signals respectively, wherein all of the baseband input signals input into every pre-distortion function, and each pre-distortion function has one output; an adder, which is configured to combine all of the pre-distorted signals output from every pre-distortion function into one combined signal; and a power amplifier (PA), which is configured to amplify the combined signal, wherein the cascade of the pre-distortion functions and the PA are linear overall. And the document also discloses a method for distorting. The document reduces the implementation cost of a pre-distorter.
