BATTERY CELL ENCLOSURE WITH ANTI-GRAVITY ELECTROLYTE DISTRIBUTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17835344 titled 'BATTERY CELL ENCLOSURE WITH ANTI-GRAVITY ELECTROLYTE DISTRIBUTION

Simplified Explanation

The patent application describes a battery cell design that includes an anode, a cathode, a liquid electrolyte, and a battery cell case. The case is designed to house the anode, cathode, and electrolyte, and it has a patterned interior wall that affects the surface tension of the electrolyte. This pattern allows the electrolyte to move against gravity and distribute itself evenly along the battery cell wall.

  • The battery cell case is configured to house the anode, cathode, and liquid electrolyte.
  • The case has a patterned interior wall that varies in surface tension between hydrophobic and hydrophilic.
  • The pattern of surface tension helps the liquid electrolyte move against gravity.
  • The electrolyte is distributed evenly along the battery cell wall due to this self-propulsion.

Potential Applications

  • This battery cell design can be used in various electronic devices that require a reliable and efficient power source.
  • It can be particularly useful in portable devices like smartphones, tablets, and laptops.

Problems Solved

  • The design solves the problem of uneven distribution of the liquid electrolyte in battery cells.
  • It ensures that the electrolyte is evenly distributed along the battery cell wall, improving the overall performance and lifespan of the battery.

Benefits

  • The self-propulsion of the electrolyte allows for a more efficient use of the battery's capacity.
  • The even distribution of the electrolyte helps prevent hotspots and improves the overall stability and safety of the battery.
  • This design can potentially increase the lifespan of the battery and reduce the need for frequent replacements.


Original Abstract Submitted

A battery cell includes an anode, a cathode, a liquid electrolyte, and a battery cell case. The battery cell case is configured to house the anode, the cathode, and the liquid electrolyte and includes a case interior wall arranged proximate one of the anode and the cathode, a battery case ceiling, and a battery case floor catching and collecting the liquid electrolyte due to force of gravity. The case interior wall defines a pattern of surface tension varying between hydrophobic and hydrophilic along the case interior wall between the battery case floor and the battery cell ceiling. The pattern of surface tension thereby facilitates self-propulsion of the liquid electrolyte in opposition to the force of gravity and a predetermined distribution of the liquid electrolyte along the battery cell wall.
