NOVELTY - The apparatus has a pouch cell (100) whose four edges are adapted to be ultrasonically welded and sealed. An electrolyte is adapted to impregnate an internal portion of the pouch cell. A positive wire harness is adapted to electromechanically couple to a positive tab (108). A negative wire harness is adapted to electromechanically couple a negative tab (110). A rectangular rack mount housing is adapted to enclose the energy storage apparatus and comprises a positive terminal and a negative terminal operatively coupled to the positive wire harness and the negative wire harness respectively.    USE - Energy storage apparatus such as ultra-capacitor energy storage apparatus and battery energy storage apparatus e.g. energy blade (RTM: stainless steel water-submersible heat exchanger designed to be used in fresh water), for delivering large power loads in heavy automotive applications. Can also be used for transportation, hybrid vehicles, power grid, board net stabilization, windmills, and dirty energy filtration applications.    ADVANTAGE - The apparatus eliminates substantial quantities of metal and wasted space used to house modern energy storage devices, utilizes previously wasted volume to house additional energy storage medium, and exchanges weight contributions from metal for weight contributions from additional energy storage medium, thus improving overall energy density and lowering manufacturing costs. The apparatus reduces waste by reducing volumes of metal required to house the energy storage apparatus in an ecologically friendly manner, reduces points of failure, achieves significant weight reduction for comparable energy densities to reduce output impedance of the energy storage device, reduces materials costs by approximately 45 % due to elimination of significant amounts of metal, yields up to 16 times more energy at a given power rating than currently available with nearly half weight and half space required. The apparatus utilizes a ultra-capacitor for regenerative braking rapid charging and intaking large amounts of energy quickly, and a balancing circuit for making regenerative braking charge to flow to the battery pouch cells without damaging battery pouches and make remaining charge to flow to ultra-capacitor pouch cells, so that energy waste is avoided in regenerative braking process.
