Battery manufacturers have been looking for chemical reactions using cheap, lightweight materials that can be produced in bulk into reliable products.
The chemical process should run in both directions so that the battery can be recharged and discharged repeatedly without causing the material to break.
It should run at a daily temperature.
These requirements help explain why batteries are weak in so many products, from mobile phones to electric cars.
While no one knows which chemical process will succeed, some companies and industrial consortia are betting on lithium --
Polymer batteries. James A.
Elsner, President and CEO of Hope Technologies, said his company is developing a "credit card --
Can run the size of the Palm batterytop computer;
Larger cars that are layered or rolled will run electric cars. Lithium-
Polymer batteries have obvious advantages.
Lithium is the lightest metal on the atomic map.
Lead, used in familiar lead
Acid battery is one of the heaviest batteries.
And other components--
Plastics and hydrocarbons-are also light.
The battery is assembled with thin lithium.
Polymer sandwiches, sometimes less than an inch thick.
Russell Moy said: "The goal of advertising is to" dispose of these things in a way that makes photographic films or tapes, paint or spray a layer on another layer. ", A senior researcher at Ford Motor. Mr.
Moy represents Ford's American advanced battery alliance in Detroit.
The group consists of three major automakers, partly funded by the federal government.
Edward O.
Riddell is the director of transportation projects at the utilities consortium Power Research Institute in Palo Alto, California.
He said: "The problem with most of the new batteries we are playing with is that they all contain rare materials.
Some work well, like nickel metal.
Some laptops are using hydrogen batteries. But Mr.
If they become more popular, Riddell says, their prices may rise because they are made of relatively scarce materials. Lithium-
There is an advantage of polymer batteries.
Solid polymer forming electrolyte--
That is, the material through which charged particles migrate to generate current.
It cannot leak, corrupt parts or release dangerous gases.
Familiar electrolyte in lead
Acid batteries have all these problems. Lithium-
Polymer batteries have powered small devices such as hearing aids.
"Let's say we can make a bigger product work, but no one has succeeded in doing so, and we have the potential to reduce it. cost, high-power, high-
"Energy batteries . "
It is also a member of the senior battery alliance management team in the United States.
Two separate teams are working on lithium.
Polymer Research by the consortium. Hydro-
The first team was formed in Quebec, 3 m and Algon national laboratories. Hydro-
Quebec, the province-owned utility, has been working on the technology for 15 years.
3 m has rich experience in manufacturing film-
From transparent glue to more foreign substances.
The Energy Department Laboratory Argonne will test the battery.
In last December, the battery consortium announced $32.
Signed 8 million research contracts with 3 m team.
The consortium signed a $27 contract.
4 million contracts with the second team, consisting of W. R.
Grace and Johnson control.
The former is a chemical company, and the latter specializes in polymers.

And price Technology in San Jose, California--
Negotiations were held with the consortium, but negotiations were interrupted at the end of the summer.
Delco says advocates of electric vehicles
The varance team may think it is about to make a big breakthrough. A. C.
Delco, a GM department, said it couldn't reach an agreement in time, so it went ahead on its own.
The two companies announced last month that they had reached an agreement with Eveready battery to combine their technology.
All teams are using polymer films of approximately plastic food packaging thickness, sandwiched between lithium alloy anode attracting positive ions and oxide cathode attracting negative ions.
Hope Technologies, which is about to be renamed Lithion Technologies Corporation, plans to build a pilot project
Expand the size of the manufacturing plant and connect individual components.
AdvertisementHope, now in Willow Grove, Pa.
It is planned to move to the new lab and company office at the Pa Plymouth meeting next month.
Its manufacturing plant there will be completed by the end of 1995.
The Valence Technology establishes a manufacturing process, but there is a problem with the product.
According to David M. , it has returned to research and development and hopes to have a product available by 1996.
Butz, vice president of marketing.
The man who designed the battery
Power-supply equipment can sometimes joke that there are lies, damn lies and promises from battery makers in this life.
In fact, battery manufacturing began.
Ups will always be in conflict with financial regulators, who say they are too optimistic.
The Securities and Exchange Commission is looking into hope technology to understand the decisions made by previous managementElsner said.
That said, sir.
Elsna's prediction is optimistic.
He believes he can build a 825-
About 6 lbs battery.
4 cubic feet allows a small car to travel 375 miles.
Calculate the assumed energy efficiency of 200 watts-
One mile an hour, less electricity than G. M. 's two-seat Impact.
The company says it has 110,000 miles of battery life.
Others are skeptical. Dr.
Deputy Secretary of Commerce leading the Clinton administration, Mary Goodallmile-per-
The gallon supercar project says advanced batteries are often more difficult to produce on a large scale than in laboratory manufacturing.
But this approach is promising.
In this country, the consortium's two largest research contracts are lithium-

S. experts say another sign of the most potential in this field is research elsewhere.
The Japanese are actively pursuing this area, they said.
