Flat pouch

Pol5Tner lithium-ion technology is also known commercially by the name LiPo. It has been commercialized more recently, particularly to serve the needs of model-making, and the need to have very varied formats of batteries, particularly in a flat pouch. LiPo technology is also to be found in electrically-assisted pedal cycles. More recently, it has been envisaged for electric vehicles or mobile devices. 

The longitudinal layer of smooth muscle in the small intestine is continuous. In the large intestine, this layer of muscle is concentrated into three flat bands referred to as taniae coli. Furthermore, the large intestine appears to be subdivided into a chain of pouches or sacs referred to as haustra. The haustra are formed because the bands of taniae coli are shorter than the underlying circular layer of smooth muscle and cause the colon to bunch up, forming the haustra. 

The pelican has perhaps the most unusual bill in the bird world. It is quite long—18 in (46 cm) in some birds— with the top part, or mandible, flat, narrow, and quite stiff. The bottom part has a solid upper edge surrounding a pouch of skin that can stretch almost endlessly to hold great quantities of fish. This soft, flexible tissue extends down onto the neck. The birds do not fly back to their nests with food in the pouch. They would not be able to keep their balance in flight. Instead, it serves as a net to catch fish. Up to 2 gal (7.6 1) of water can be taken in and then forced out through the closed mandibles, leaving the eaptured fish behind. They are then swallowed. 

Retortable pouches can be made from combinations of foil, polyester, nylon, polypropylene, HD polythene, provided the laminant (or the process of lamination) employed will withstand the autoclaving conditions of temperature and moisture. Due to the flat shape of the pouch and high surface area, sterilisation times can usually be reduced compared with cans. 

The term stand-up pouch refers to a pouch that is able to support itself in an upright position when it is filled with product. Such pouches contain gussets that expand when the product is added, providing a relatively flat base to the pouch. Such pouches are increasingly replacing more rigid structures such as cans and bottles, for both dry products and liquids. 

Fig. 8.8 The flat plate/polymer cells may use a polymer pouch construction with an aluminum barrier layer. An auxiliary chamber may be used to contain the gases generated during formation. After formation the auxtiiary chamber is penetrated with a needle and any gas formed during formation is evacuated. The opening between the two chambers is then sealed...

Using this type of electrolyte, it is possible to make flat and flexible batteries, without the risk of the electrolyte leaking if the external casing is broken. This casing is a pouch which is metalized on the outside and covered on the inside surface with a heat-sealable polymer. This type of battery is also lighter, because there is no solid metal casing.
