A battery comprise: a housing made by a metal or a metal alloy; a battery core in the housing comprising a positive plate, a separator and a negative plate; an electrolyte in the housing; a cover assembly having a positive terminal electrically connected with the positive plate and a negative terminal electrically connected with the negative plate; and a protection component to prevent the housing from being corroded by the electrolyte.

Lithium-ion battery

An electrochemical storage cell having a coiled core is disclosed. The coiled core includes a cathode sheet, an anode sheet, and a separator sheet. An anode connector is connected with the anode sheet at a first end of the coiled core and a cathode connector is connected with the cathode sheet at a second, opposite end of the coiled core. The coiled core has a length Land a width Wand each connector has a width W. The length of the coiled core L, width of the coiled core W, and width of each connector Whave the relationship 0&#x3c;(W&#x2212;W)/L&#x3c;0.37.
