`Contact at least three suppliers of cylindrical Ni-Cds for
`avallability of cells and who would be able and willing to work on
`develiopment. contracts with PM. Currentily, Sanyo is the only supplier of
`NSOAAA. However, Panasonic and Toshiba could also make that configuration if
`required. The immediate need from these manufacturers are:

`
`(2)
`
`(3)
`
`Request deliverable NSOAAA size by 1994 ( 300,000 to 500,000).
`
`Request development undertakings (2 to 5 man-year) to reduce
`weight/volume of N5Q0AAA: by 20 to 25%.
`
`improved design of category (2) using metal hydride negative
`Request
`electrode with some small but further improvements in the size.
`
`Extensive interfacing with each manufacturer and battery
`development testings will need' to be made on {2) and (3} to determine level
`of improvement in performance and safety. It may only be necessary. to
`identify one able and willing manufacturer initially. But one. back-up is
`necessary who can take over from where one manufacturer left-off in the
`development program. This may be costly, but. will prove to be more worthwhile
`in terms of guaranteed delivery of the product on a timely basis,

`
`Current mother pack today can be 6-Ni-Cd of appropriate capacity
`(72-849/23-30cc). Current Ni-MH are nott available in a configuration other
`than "AA" and "C" sizes.
`Iff they were available,
`then the Ni-MH would give a
`reduction in weight and volume of about one-third over Ni-Cd.

`
`This is an exciting new systemcurrently being commerciializedby
`Sony Energytec for cellular and cordless telephone applications. Because of
`the rate limitation imposed on this system by the conductivity of the non-
`aqueous electrolyte, this system is not advantageous. for an eight-puff device
`since: the size reduction is: negligible. This remains to be evaluated once
`more data is available. However, it has been projected that a larger pack
`than: what might be fior an eight-puff may be sufficient ta power an all day
`smoke att 20Ws energy. The projected size is 50-60% of the current available
`size: (40g/16.8cc). The “AA™ size which may be available has been requested
`through Jewett Automation. This may be more than adequate for tihe mother
`pack. Unfortunately, smaller configuratiions. are undévailable but devellopment
`plans with a number of Japanese battery companies may help bring about this
`need. This system holidds the: highest promise for the lithium power source. If
`enough attention is paid to: this technology right. away,
`then the right
`battery may be available by 1994 for an all day smoking device. The potential
`for this system is: there for use as an all day smoke or as the mother pack by
`1994.
`
`As described above, this appears to be the best system for the
`long-term effort today and canprovide an all day smoke in a reasonably small
`size (20g/8cc).. However, with the rate limitation and lower energy density
`than conventional Lithium rechargeables, it is. unlikely that a small size may
`be ever available for a cigarette size device.
`
`This system holds the highest promise for an all day smoke in a
`cigarette size device providing 10Ws is the energy requirement. The snag is
`that it is unclear where this technology is going. Developmental effort is.
`not aimed at making small size cells. Much of the effort is aimed at making
`batteries for lap-top computers or other largex applications. However,
`initial. results: on the laboratory scale indicates that this system is capable
`of rates as high as 50C and with excellent cycling characteristics.
`It. is
`anticipated that it may be at least 5 to idyears with heavy developmental
`backing from PM when this technology may be in a position to: be applied for
`the cigarette sifze device. A humongous R & D task is required in the
`meantime. For an energy requirement greater than 10Ws,
`there is no system
`cunrently, and nor will there be one in ten years time that will provide an
`all day smoke from a Cigarette size device. The energy requirement has tio be
`reduced for a pleasing subjective in order to realize the ultimate goal.
