a powertrain

technical field

The utility model relates to the technical field of batteries, in particular to a power assembly.

Background technique

Climate change, energy and environmental issues are long-term problems faced by human society. Lithium-ion batteries are one of the ways to solve the energy crisis. Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries.

The current lithium-ion battery powertrain has low structural strength, poor heat dissipation, complicated installation, and troublesome maintenance.
