A battery module having a battery cell assembly that is free from module banding is provided. The assembly includes an expandable battery cell having a first and second face. The assembly further includes a growth plate having a first and second face. The first face of the battery cell contacts the second face of the growth plate. The battery cell assembly further includes a first cell frame securing the growth plate on at least two sides and a second cell frame that contacts the second face of the battery cell. The first face of the growth plate includes a plurality of spacing features disposed along the first face of the growth plate that offset the first face of the growth plate from the first cell frame, which creates a cavity between the growth plate and the first cell frame. The cavity decreases when the battery cell expands.

An electrochemical storage device comprises a plurality of layer electrodes each including a first charged sector and a second charged sector. The plurality of layer electrodes are assembled with respect to each other such that the first charged sector of a first plate of the plurality of layer electrodes is laid below the second charged sector of a second plate of the plurality of layer electrodes located immediately above the first plate. The charges of the first charged sectors of the first and second plates have a first sign and the charges of the second charged sectors of the first and second plates have a second sign that is opposite the first sign. The device also comprises a separator sector located, and enabling ionic charge exchange, between the first charged sector of the first plate and the second charged sector of the second plate.

Lead-acid battery design having versatile form factor

A battery system and a method for cooling the battery system are provided. The system includes an evaporative cooling member, and a battery module having a housing, a battery cell, and a solid cooling fin. The housing holds the battery cell therein. The solid cooling fin has first and second panel portions. The first panel portion is disposed against the battery cell. The second panel portion extends through the housing and is disposed on the evaporative cooling member. The solid cooling fin conducts heat energy from the battery cell to the evaporative cooling member. The evaporative cooling member receives a gaseous-liquid refrigerant and transitions the gaseous-liquid refrigerant into a gaseous refrigerant utilizing the heat energy received from the solid cooling fin.
