The working principle of a battery rolling machine revolves around the application of controlled pressure to the electrode sheets. The machine typically consists of two rollers, one stationary and the other driven by a motor. The electrode sheet is fed between these rollers, where it undergoes a rolling process. Steps in the Rolling Process
Rolling of lithium metal to form the desired lithium strips or sheets has been attempted but when lithium is rolled against a metal roller, it sticks to the metal of the roller. Thus rolling has not been used to commercially produce strip lithium by conventional rolling methods.
DESCRIPTION OF THE INVENTION Lithium metal can be cold rolled into sheets of even thickness by cornpressively rolling the lithium between substantially smooth surfaces of a solid polymeric composition which is nonreactive with lithium and has a critical surface tension of not over 46 dynes per centimeter at 20 C.
Specifically speaking, the operating temperature range of the lithium battery needs to be limited to 25–40 °C, and the maximum temperature difference of battery module inside the battery pack does not exceed 5 °C to ensure the battery performance and minimize thermal runaway , .
In this paper, a roll bond liquid cooling plate (RBLCP) is designed and fabricated for thermal management of energy storage batteries. The following conclusions can be drawn: Compared with other studied, roll bond liquid cooling plate has obvious advantages.
Lithium batteries are made on similar lines to jelly roll technology, although the ingredients are different. There are four main parts rolled up in a cylinder. First, there are the cathode and the anode containing potential for the spark of life. Then there are the electrolyte – still usually liquid – and the separator that acts as gate keeper.
