High-temperature-resistant sodium ion cylindrical battery

Abstract

The invention provides a high-temperature-resistant sodium ion cylindrical battery, and relates to the technical field of batteries, the high-temperature-resistant sodium ion cylindrical battery comprises a battery module bottom plate, the upper end surface of the battery module bottom plate is provided with a plurality of bottom plate battery mounting holes, and each bottom plate battery mounting hole is fixedly provided with a cylindrical unit battery; a plurality of heat dissipation aluminum strips are integrally and fixedly connected to the upper end of the battery module bottom plate. According to the scheme, the battery module bottom plate and the battery module upper plate are fixedly arranged at the upper end and the lower end of each cylindrical unit battery respectively; a plurality of heat dissipation aluminum strips on the surface of the upper end of a battery module bottom plate can achieve the effect that the lower end dissipates heat of a cylindrical unit battery, and when a battery detection mechanism of the new energy vehicle detects that the temperature of the battery is too high, an air conditioner carried on the vehicle is started, and an air outlet of the air conditioner is communicated to an air conveying pipe; and low-temperature airflow is conveyed into the circulating ventilation disc through the air conveying pipe, so that the cylindrical unit batteries are actively cooled, and the battery modules can be protected.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a high temperature resistant sodium ion cylindrical battery. Background technique [0002] The research of sodium-ion battery first started around the 1980s, and the electrode materials such as MoS2, TiS2 and NaxMO2 that were designed and developed in the early stage have unsatisfactory electrochemical performance, and the development is very slow. Finding suitable Na-ion electrode materials is one of the keys to the practical application of Na-ion energy storage batteries. Since 2010, a series of positive and negative electrode materials have been designed and developed according to the characteristics of sodium-ion batteries, which have greatly improved in capacity and cycle life. Anionic, Prussian blue, and oxide-based materials, especially NaxMO2 (M=Fe, Mn, Co, V, Ti) with a layered structure, and its binary and ternary materials show good charge-discharge specific capacit...
