TL;DR: In this article, the so-called Lithium Polymer Battery (LPB) is proposed, which can be easily fabricated in the form of a thin film (typically 50 µm thickness) by a number of convenient casting techniques.
Abstract: The discovery and the characterization of ionically conducting polymeric membranes (see Chapters 1 and 2) have provided the interesting possibility of developing new types of lithium batteries having a thin-layer, laminated structure. Various academic and industrial laboratories [1, 2, 3, 4, 5] are presently engaged in the development of this revolutionary type of battery, i.e. the so-called Lithium Polymer Battery (LPB). The key component of the LPB is the polymeric ionic membrane which acts both as electrolyte and separator; furthermore, the membrane can be easily fabricated in the form of a thin film (typically 50 µm thickness) by a number of convenient casting techniques.

TL;DR: In this paper, the authors developed a solid-polymer electrolyte that has a high ionic conductivity of σ = 2 × 10 −3 S cm −1 at 25 °C, and using this electrolyte, they then developed an ultra-thin film primary battery of the size of a credit card and with a thickness of 0.1 mm.

TL;DR: The nickel metal hydride (Ni-MH) battery is an attractive, available power source for consumer electronic applications such as portable computers, cellular communications, and camcorders as mentioned in this paper.
Abstract: The nickel metal hydride (Ni-MH) battery is an attractive, available power source for consumer electronic applications such as portable computers, cellular communications, and camcorders. Commercially available Ni-MH batteries can substitute for nickel cadmium (Ni-Cd) batteries cell for cell, with almost indistinguishable voltage characteristics, but provide 25-40 percent more energy and are free of environmentally undesirable cadmium. Ni-MH batteries offer excellent cycle life of more than 500 cycles.

Abstract: A new type of rechargeable battery in which lithium ions shuttle between a lithium-manganese oxide electrode and a carbon electrode was unveiled recently by chemists from Bell Communications Research (Bellcore), Red Bank, N.J. The new battery—still experimental—is safer, longer lasting, and potentially cheaper to manufacture than other lithium-ion batteries. In addition, it provides three times the energy of nickel-cadmium cells, the most popular type of rechargeable battery. Bellcore scientists believe the new battery could replace nickel-cadmium and small lead-acid batteries in many applications. Bellcore's brainchild is known as a "rocking chair" battery because of the back-and-forth motion of its lithium ions during the cell's charging and discharging cycles. The battery is charged when lithium ions released from the cathode or positive electrode (Li 1+x Mn 2 O 4 ) flow to the anode or negative electrode and intercalate themselves within its graphitic lattice. During discharge, the reverse process occ...
