PATENTED RECHARGEABLE ALKALINE MANGANESE CELLS
PROJECT
OVERVIEW OF THE RAM™
TECHNOLOGY
COLLABORATOR’s RAM™ Technology was developed under the guidance of Dr. Karl Kordesch, an internationally recognized electrochemist who is Professor Emeritus at the Technical University of Graz, Austria and a founding shareholder of the Company.
The RAM™ Technology has been developed by COLLABORATOR to maximize commercial viability while minimizing environmental impact. Compared with other battery systems, RAM™ batteries provide users with a low cost, environmentally responsible product, completely interchangeable with today’s household batteries.
RAM™ batteries contain essentially no hazardous toxic substances. In 1992, COLLABORATOR, supported by grant initiatives of the Canadian Ministry of the Environment, successfully eliminated mercury from RAM™ batteries, making it one of the first mercury free alkaline battery systems in the world. RAM™ batteries also do not include other toxins such as cadmium, which represents a significant environmental hazard. This, combined with the rechargeable nature of the RAM™ batteries, which results in less total waste than with disposable batteries, makes the RAM™ Technology one of the most environmentally responsible battery systems in the world.
RAM™ batteries also offer the advantages of rechargeability, long shelf life, high initial capacity and stability in high temperature conditions.
RAM™ batteries benefit from very low self-discharge rates, to a degree unmatched by any other rechargeable battery on the market. All other rechargeable technologies exhibit high self-discharge rates, particularly at higher temperatures. Only RAM™ batteries are capable of keeping their charge, even at elevated temperatures of up to 65°C. Also, RAM™ batteries do not exhibit any problems with “memory effect” and will perform better in the case of shallow discharge and frequent recharge.
In addition, RAM™ batteries are uniquely suitable for solar charging applications, particularly in developing countries where sunlight is abundant and connection to electrical power a scarce commodity. All competitive rechargeable technologies exhibit self-discharge characteristics at an accelerated rate in high temperatures, thereby reducing their solar charging performance.
COLLABORATOR uses an industry proven process to manufacture RAM™ batteries which is more efficient than the process used to manufacture other rechargeable batteries. For that reason, RAM™ batteries can be produced at a lower per unit cost than NiCad, NiMH or Li-Ion batteries. The raw materials required for RAM™ batteries are readily available from a variety of sources internationally.
A summary of the performance characteristics and typical data for the RAM™ Technology as compared to other disposable and rechargeable battery chemistries is as follows.
Compared with disposable batteries, RAM™ batteries offer the following advantages:
|
Rechargeability |
Depending on
the application and the frequency of recharging, a RAM™ battery can be
discharged and recharged between 25 and over 500 times. |
|
Longer
Operating Time |
A RAM™
battery, in its first cycle, can provide up to four times the service
hours of a zinc carbon battery and up to 90% of the service hours of a
disposable alkaline battery. Over its useful life, a RAM™ battery can
replace between 100 and 200 zinc carbon batteries and between 20 and 50
disposable alkaline batteries. |
|
Environmental
Superiority |
The
rechargeable nature of RAM™ batteries leads to a reduction of solid
wastes. |
|
Cost
Effectiveness |
Although RAM™
batteries cost approximately 15% more to produce than, and sell at retail
for a premium over, disposable alkaline batteries, they are also more
economical due to their rechargeability. |
|
Shelf
Life |
Similar to
disposable alkaline batteries, RAM™ batteries retain 80% of their energy
for at least five years. However,
RAM™ batteries (unlike disposables) may then be recharged for use. |
|
Convenience |
RAM™
batteries are commercially available as loose consumer batteries and are
fully interchangeable with disposable batteries. |
Compared with other rechargeable battery chemistries such as NiCad, NiMH or Li-Ion, RAM™ batteries offer the following advantages:
|
Longer Operating Time |
A RAM™
battery can, on first discharge, provide up to three times the service
hours of a NiCad battery or one and a half times the service hours of a
NiMH battery, and better or equal service hours than a NiCad battery over
the first 25 cycles, depending on discharge conditions. |
|
Self Discharge |
At room
temperature (25°C),
RAM™ batteries retain 80% of their energy for at least five years
compared with NiCad, NiMH and Li-Ion batteries, which would lose almost
all of their capacity in less than one year.
Even at elevated temperatures, RAM™ batteries have better
capacity retention. In contrast, NiCad, NiMH and Li-Ion batteries would
lose almost all of their capacity in approximately one month at elevated
temperatures (that is, 45-65°C). |
|
Environmental Superiority |
NiCad batteries
contain approximately 18% cadmium by weight. Cadmium, a heavy metal, is
classified as hazardous waste by the U.S. Environmental Protection Agency
and is subject to legislation in many states in the United States and in
other countries worldwide. Legislation affecting the sale and collection
of products which include heavy metals has been proposed in the European
Union and which, if enacted, may lead to a complete ban on the use of
cadmium in batteries. RAM™
batteries contain essentially no hazardous toxic substances and may
generally be disposed of in land fill sites without the requirement for
special handling. |
|
Safety |
RAM™
batteries have demonstrated consumer safety in actual use since 1993, with
no accidents reported. Li-Ion
batteries, on the other hand, have a very reactive chemistry due to the
flammable nature of the electrolyte and rely on built in (expensive)
safety devices to ensure consumer safety.
|
|
Lower Cost |
The wholesale
cost of RAM™ batteries is approximately 50% that of NiCad, 33% that of
NiMH and 16% that of Li-Ion batteries. |
|
Ready For Use |
NiCad, NiMH and
Li-Ion batteries are manufactured in the discharged state and must be
recharged prior to use and, due to their rapid self-discharge properties,
after periods of storage. RAM™
batteries have the convenience of being fully charged and ready for use
after purchase. |
RAM™
batteries are ideally suited for use in any battery operated device that uses
disposable alkaline or zinc carbon batteries and any low drain device that
currently uses other rechargeable batteries.
The batteries can be used in all of the following devices: flashlights,
radios, television, stereo and other remote controls, cassette players, portable
compact disk players, personal digital assistants (“PDAs”), wireless
communications devices, electronic and video games, portable phones, notebooks,
portable LCD televisions, portable stereos, hand-held electronic games,
camcorders, cameras and many other devices.
In 1997 (the most recent year for which reliable figures are available), worldwide sales of small format batteries (both disposable and rechargeable segments) were approximately U.S.$23.8 billion. The Company estimates that sales could grow to approximately U.S.$35.9 billion by 2002. The disposable market includes all alkaline and zinc carbon batteries, while the rechargeable market includes all NiCad, NiMH, Li-Ion and RAM™ batteries.
The table below illustrates, on a segmented basis, sales of small batteries in 1997 together with the Company’s estimate of potential growth in the size of the market.

It
is obvious that India has the potential to develop a huge market for alkaline
technology as its low per capita battery consumption and low penetration of
alkaline improves. The developed countries, because of higher personal incomes,
have switched substantially to the more expensive, but longer lasting, alkaline
cells. Developing countries are bound to follow suit.
If
alkaline cells could be made to last longer through recharging so that, for the
same price, more energy would be available from the same cell, this would
immediately strike a chord with the economy-conscious population of developing
countries. This is the business opportunity that this proposal
attempts to exploit.
The
present Indian market is confined largely to ZnC cells as these were the only
ones made here so far. More modern cells have been coming in through imports.
Only recently have alkaline single-use cells started being made in India. In
1996 the quantity of ZnC produced was 1800 million and growing at about 10% per
year.
New Technology
UNIQUE PATENTED TECHNOLOGY OF RECHARGEABLE ALKALINE MANGANESE (RAM) CELLS BRING THE BEST OF BOTH WORLDS TOGETHER to attack the market on both sides. Being Alkaline, they perform far better in shelf-life and operating life compared to Zn-C. In addition, they can be recharged many times thus giving long life advantage over the present Discardable Alkaline Cells. For same performance, RAM cells' operating life-time cost turns out to be much less than of DAC and even farther less than Zn-C. In several practical tests with medium drain portable equipments, one RAM cell with 50 recharges gave the same operating life as replacing as many as 17 DAC or 50 ZnC cells in the same application; and there was still more life left in the RAM cell.
RAM cells also throw a challenge to NiCd at medium current drains. Due to its 1.2 volts, NiCd needs 5 costly cells for every 4 low-cost RAM cells. While RAM shelf life is 5 years, NiCad self-discharges at 1% per day at 30 Centigrade and 3% per day at 45 Centigrade. On each operation discharge, RAM provides 3 times the hours of NiCad. RAM yields more energy per size and weight than NiCad making it more valuable for portable and pocketable equipments.
· Penetrate the market of fast obsoleting Zn-C cells
· Capture market of single use Alkaline cells
· Replace rechargeable NiCd cells in many applications
This new technology results in a very cost-effective product which can be sold at a small premium over DAC. The technology is already licensed in Korea, Canada, USA. Products are being designed-in by dozens of well known OEM in these countries.
MANUFACTURING
EQUIPMENT
While COLLABORATOR sells high quality, state of the art turnkey manufacturing equipment for the production of RAM™, it is worth noting that since the construction of RAM™ cells is similar to that of primary alkaline cells (PAM), it is possible that existing equipment designed for producing PAM product could be converted to enable the manufacture of RAM™. An complete review and assessment would have to be completed to determine the feasibility of converting PAM equipment.
|
|
The highly automated Chemical Processing Systems of the turnkey line are made up of the Cathode, Anode and Electrolyte Processing Systems. These systems have the capacity to support up to five cell assembly lines (excluding “D” size) and need not be duplicated for the addition of future lines. |
|
|
These systems comprise the operations of graphite coating of purchased cans, pellet pressing of cathode rings, and press fitting of pellets into the console. |
|
This system comprises the operations of welding of negative cap to nail and insertion of welded part to the moulded top seal. |
|
|
The Final Cell Assembly line includes all processes required to complete the assembly of cells. |
|
|
Test and Label Systems include electrical test function and heat-shrinking of battery labels onto finished cells. |
