  • Caseless battery
    Patent number: 5270133
    Abstract: A battery is prepared by dipping battery elements (which may be surrounded by a thin, lightweight material, such as a plastic bag) into a liquid encapsulating, acid-resistant liquid material such as a rubber or resin. Individual elements can be connected either before or after hardening of the liquid to create a battery of the desired voltage. Heavy thermoplastic resin containers need not be used, and the weight of the resultant battery is thereby substantially reduced.
