Provided are a novel boron-containing compound and an electrolyte solution additive for a secondary battery including the same. The electrolyte solution for a secondary battery provided in one embodiment includes the novel boron-containing compound, thereby suppressing the decomposition of an electrolyte solution to improve the capacity and the life characteristics of a battery.

Boron-containing compound and electrolyte solution additive for secondary battery including the same

The present disclosure relates to a novel boron-containing compound and an electrolyte additive for a secondary battery containing the same. An electrolyte for a secondary battery provided in one embodiment contains the novel boron-containing compound, such that decomposition of the electrolyte may be suppressed, thereby improving a capacity and a lifespan of the battery.

Boron-containing compound and electrolyte additive for secondary battery containing the same

An apparatus of testing an all-solid state secondary battery by nail penetration includes a pressurizing unit pressurizing a battery cell, a penetrating member inserted into a through-hole provided in the pressurizing unit to pass through the battery cell, and an auxiliary pressing unit disposed between the pressurizing unit and the battery cell and transferring pressure applied by the pressurizing unit to the battery cell. The auxiliary pressing unit is disposed between the through-hole and the battery cell in a form to block the through-hole.
