What are the properties of anode materials (lithium, carbon, aluminum, lithium titanate, etc.)?

(1) Layered structure or tunnel structure, which is conducive to excavation;

(2) Stable structure, good charge and discharge reversibility, and good cycle performance;

(3) Insert and remove as many lithium batteries as possible;

(4) Low redox potential;

(5) The first irreversible discharge capacity is low;

(6) Good compatibility with electrolytes and solvents;

(7) Low price and convenient materials;

(8) Good security;

(9) Environmental protection.

What is the general way to increase the energy density of the battery?

(1) Newly added the ratio of positive and negative active substances;

(2) New positive and negative material specific volume (gram capacity);

(3) Lose weight.
