NOVELTY - The storage (13) has energy storage housing that comprises soil which is protected from a substance passage from an operating room (2), and is thermostated by geothermal energy, partially below a ground line (1). An isolation or insulation (14) which releases an extinguishing agent (11) in the event of an incident or add particles, is comprised. A heat guidance amplifier (17) is thermostatically controlled. The energy storage housing is released and removed repeatedly as a simple module or battery under all-pole disconnection of a battery receptacle (12).    USE - High-performance or high energy storage e.g. degassing free high performance or high energy storage (claimed) for degassing free batteries e.g. lithium-ion batteries of electrical installations mounted in modern electric and hybrid vehicles. Can also be used in nickel?metal hydride (Ni-MH) batteries.    ADVANTAGE - The quality of care directly in consumption is ensured. The loss or impairment of the consumer is prevented. The protection against power failures or fluctuations in the power quality is enhanced. The energy density is suffered by optimizing for maximum power densities. The optimization with respect to the different technical characteristics leads to an undesirable increase in cost is achieved. The high current carrying capacity is required, to release high performance relative to the amount of energy stored and the memory in a short time to recharge. Therefore, a secure handling and operation which specify durable, safer and more efficient represent solutions in the operating room are carried out. The serviceability is increased. The heat of the battery is reduced or effectively curb and the environmental pollution is reduced by gases and particles into the environment. The effects of an arc are reduced further by increasing the size and duration of the short-circuit current limited by appropriate unit.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method of providing an external energy storage; and    (2) a method for thermostating a degassing free high performance or high energy storage in the operation space.
