Problems solved by technology
Existing technology At home and abroad, underwater batteries are mainly packaged through pressure-resistant shells. With the increase of the operating depth of deep-sea underwater scientific research equipment, the pressure to be withstood is also increasing. The pressure-resistant shells for encapsulating lithium batteries Generally, stainless steel, aluminum alloy or titanium alloy materials are used, but this will lead to a very large volume and weight of the underwater battery device, seriously reducing the energy density of the underwater battery, and will also seriously affect the effectiveness of the deep sea underwater scientific research equipment. load
