BATTERY UNIT, AND BATTERY, POWER CONSUMING DEVICE AND PREPARATION APPARATUS ASSOCIATED THEREWITH - A simplified explanation of the abstract

This abstract first appeared for US patent application 18352233 titled 'BATTERY UNIT, AND BATTERY, POWER CONSUMING DEVICE AND PREPARATION APPARATUS ASSOCIATED THEREWITH

Simplified Explanation

The patent application describes a battery unit with improved safety and longer service life.

  • The battery unit includes an electrode assembly with two electrode plates of opposite polarities.
  • The electrode plates have a coated region with an active material layer and an uncoated region for connecting to an electrode terminal.
  • A hardness increasing layer is applied to the surface of the uncoated region.
  • The hardness increasing layer has an elasticity modulus greater than 6 Gpa.
  • The hardness increasing layer helps alleviate battery safety issues caused by vibration during use.
  • The battery unit's service life is prolonged due to the improved safety measures.


Original Abstract Submitted

Provided are a battery unit, and a battery, a power consuming device and a preparation apparatus associated therewith. The battery unit comprises: an electrode assembly comprising two electrode plates that have opposite polarities, a coated region and an uncoated region connected to each other being formed on the electrode plate, the coated region being coated with an active material layer, and the uncoated region being used for connecting to an electrode terminal of the battery unit; wherein a surface of the uncoated region is provided with a hardness increasing layer, and the hardness increasing layer has an elasticity modulus greater than 6 Gpa. By providing the hardness increasing layer on the surface of the uncoated region, the battery unit of the embodiments of the present application can alleviate the problem of battery safety caused by vibration during the use of the battery and prolong the service life of the battery.
